Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Overview	Business Overview Civitas Solutions, Inc. (“Civitas”), through its wholly-owned subsidiaries (collectively, the “Company”), is the leading provider of home- and community-based health and human services to adults and children with intellectual and/or developmental disabilities, acquired brain injury and other catastrophic injuries and illnesses; and to youth with emotional, behavioral and/or medically complex challenges. Since the Company’s founding in 1980, the Company has evolved into a diversified national network providing an array of high-quality services and care in large, growing and highly-fragmented markets. The Company currently provides services to individuals with intellectual and/or developmental disabilities (“I/DD”), individuals with catastrophic injuries and illnesses, particularly acquired brain injury (“ABI”), youth with emotional, behavioral and/or medically complex challenges, and elders in need of day health services to support their independence. As of September 30, 2018 , the Company operated in 36 states, serving approximately 12,700 individuals in residential settings and approximately 19,000 individuals in non-residential settings. The Company designs customized service plans to meet the individual needs of those served by the Company, which it delivers in home- and community-based settings. Most of the Company’s service plans involve residential support, typically in small group homes, host home settings, or specialized community facilities, designed to improve the quality of life of the individuals served by the Company and to promote their independence and participation in community life. Other services offered include supported living, day and transitional programs, vocational services, case management, family-based and outpatient therapeutic services, post-acute treatment and neurorehabilitation, neurobehavioral rehabilitation and physical, occupational and speech therapies, among others. The Company’s customized service plans offer individuals as well as the payors of these services, an attractive, cost-effective alternative to health and human services provided in large, institutional settings. Civitas is the parent of a consolidated group of subsidiaries that market their services under The MENTOR Network tradename. NMH Holdings, LLC (“NMHH”) is a wholly owned subsidiary of Civitas and National Mentor Holdings, Inc. (“NMHI”) is a wholly owned subsidiary of NMHH. The financial results of Civitas are primarily composed of the financial results of NMHI and its subsidiaries on a consolidated basis. We have four operating divisions, Community Support Services ("CSS"), Specialty Rehabilitation Services (“SRS”), Children & Family Services ("CFS") and Adult Day Health ("ADH"). Each operating division represents a reportable segment except ADH which is included within Corporate and Other. As of October 1, 2018, Community Support Services and Children & Family Services are new names for the operating divisions formerly referred to as Intellectual and Developmental Disabilities ("I/DD") and At-Risk Youth ("ARY") respectively. There were no changes to the composition of the operating divisions as a result of these name changes.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions between the Company and its subsidiaries have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. On an on-going basis, we evaluate our estimates and judgments and methodologies. Adoption of New Accounting Pronouncements Stock Compensation The Company adopted the guidance in Accounting Standards Update ("ASU") No. 2016-09 Compensation - Stock Compensation - Improvements to Employee Share-Based Payments Accounting (ASU No. 2016-09), on October 1, 2017. Under this standard, entities are permitted to make an accounting policy election to either estimate forfeitures on share-based payment awards, as previously required, or to recognize forfeitures as they occur. The Company has elected to recognize forfeitures as they occur and the impact of that change in accounting policy has been recorded as a $0.2 million cumulative effect adjustment to increase accumulated deficit as of October 1, 2017. ASU No. 2016-09 requires that all income tax effects related to settlements of share-based payment awards be reported in earnings as an increase (or decrease) to income tax expense (benefit). Previously, income tax benefits at settlement of an award were reported as an increase (or decrease) to additional paid-in capital to the extent that those benefits were greater than (or less than) the income tax benefits reported in earnings during the award’s vesting period. The requirement to report those income tax effects in earnings has been applied on a prospective basis to settlements occurring on or after October 1, 2017, and the impact of applying the guidance was not material to the consolidated financial statements for the year ended September 30, 2018. Application of the guidance may result in fluctuations in the Company’s effective tax rate depending on how many options are exercised, how many restricted stock units vest and the volatility of the Company’s stock price. ASU No. 2016-09 also requires that all income tax-related cash flows resulting from share-based payments be reported as operating activities in the statement of cash flows. Previously, income tax benefits at settlement of an award were reported as a reduction to operating cash flows and an increase to financing cash flows to the extent that those benefits exceeded the income tax benefits reported in earnings during the award’s vesting period. The change in classification of cash flows has no impact to prior periods, and the Company has elected to apply the changes in cash flow classification on a prospective basis. Income Taxes In March 2018, the FASB issued ASU No. 2018-05 Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (ASU 2018-05). The update provides guidance associated with the accounting and disclosures around the enactment of the Tax Cuts and Jobs Act and the Securities and Exchange Commission’s Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”). This guidance was effective upon issuance and has been applied to the consolidated financial statements and related disclosures beginning in the second quarter of fiscal 2018, see Note 18 for the disclosures related to this amended guidance. Fair Value Measurements The accounting standard for fair value measurements defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and requires detailed disclosures about fair value measurements. Under this standard, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The valuation techniques are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect certain market assumptions. This standard classifies these inputs into the following hierarchy: Level 1 Inputs - Quoted prices for identical instruments in active markets. Level 2 Inputs - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 Inputs - Instruments with primarily unobservable value drivers. The fair value hierarchy level is determined by asset class based on the lowest level of significant input. In periods of market inactivity, the observability of prices and inputs may be reduced for certain instruments. This condition could cause an instrument to be reclassified between levels. During the years ended September 30, 2018 and 2017 , there were no transfers between levels. Cash Equivalents The Company considers short-term investments with maturity dates of 90 days or less at the date of purchase to be cash equivalents. As of September 30, 2018 and 2017 , the Company did not have any cash equivalents. Restricted Cash Restricted cash consists of a cash collateral account set up to support the issuance of letters of credit under the Company’s institutional letter of credit facility and funds provided from government payors restricted for use by individuals served by the Company. Concentrations of Credit and Other Risks Financial instruments that potentially subject the Company to credit risk primarily consist of cash and cash equivalents, self-insurance receivables and accounts receivable. Cash and cash equivalents are deposited with federally insured commercial banks in the United States, which, at times may exceed federally insured limits of $250 thousand . The Company has not experienced any losses in such accounts. As of September 30, 2018 , our accounts exceeded federally insured limits by $58.1 million . The Company derives approximately 89% of its revenue from state and local government payors. These entities fund a significant portion of their payments to the Company through federal matching funds, which pass through various state and local government agencies. Of the 36 states the Company operates in, Minnesota is our largest state and generates revenue from our contracts with state and local governmental payors which accounted for approximately 16% , 15% , and 15% of our net revenue in fiscal 2018 , 2017 and 2016, respectively. Contracts with state and local governmental payors in California, our second largest state, accounted for 10% of our net revenue in fiscal 2018 and 2017. No other states accounted for 10% or more of our net revenue during fiscal years 2018, 2017, or 2016. Revenue Recognition Revenue is reported net of allowances for unauthorized sales and estimated sales adjustments. Revenue is also reported net of any state provider taxes or gross receipts taxes levied on services the Company provides. Sales adjustments are estimated based on an analysis of historical sales adjustments and recent developments in payment trends. Revenue is recognized when evidence of an arrangement exists, the service has been provided, the price is fixed or determinable and collectability is reasonably assured. The Company recognizes revenue for services performed pursuant to contracts with various state and local government agencies and private health care agencies. The payment terms and rates of our contracts vary by jurisdiction and service type. The Company has four types of contractual arrangements with payors which include negotiated contracts, fixed fee contracts, retrospective reimbursement contracts and prospective payments contracts. Under the Company's units-of-service contracts, which include negotiated contracts and fixed fee contacts, revenue is recognized at the time the service is performed. Under the Company's cost reimbursement contracts, which include retrospective reimbursement contracts and prospective payment contracts, revenue is recognized at the time the service costs are incurred. For the Company’s cost-reimbursement contracts, the rate provided by the payor is based on a certain level of service and types of costs incurred in delivering the service. From time to time, the Company receives payments under cost-reimbursement contracts in excess of the allowable costs required to support those payments. In such instances, the Company estimates and records a liability for such excess payments. At the end of the contract period, any balance of excess payments is maintained as a liability until it is reimbursed to the payor or until the Company has exhausted efforts to make the reimbursement. Revenue in the future may be affected by changes in rate-setting structures, methodologies or interpretations that may be enacted in states where the Company operates or by the federal government. Cost of Revenue The Company classifies expenses directly related to providing services as cost of revenue, except for depreciation and amortization related to cost of revenue, which are shown separately in the consolidated statements of income. Direct costs and expenses principally include salaries and benefits for service provider employees, per diem payments to independently contracted host-home caregivers (“Mentors”), residential occupancy expenses, which are primarily composed of rent and utilities related to facilities providing direct care, certain expenses, such as food and medicine and transportation costs for individuals requiring services, professional and general liability expense, employment practices liability expense and workers’ compensation expense. Property and Equipment Property and equipment are recorded at cost and are depreciated using a straight-line method when placed into service, based on their estimated useful lives as follows: Asset Description Estimated Useful Life (in years) Land Indefinite Building 30 Building improvements 10 Leasehold improvements Not to exceed 7 years or length of lease Vehicles 5 Computer hardware and software 3 Furniture, fixtures and equipment 3-5 Capital lease assets are depreciated over the lesser of the lease term or the useful life of the asset. Expenditures for maintenance and repairs are charged to operating expenses as incurred. When assets are sold or retired, the corresponding cost and accumulated depreciation are removed from the related accounts and any gain or loss is recorded in the period of the sale or retirement. Accounts Receivable Accounts receivable primarily consist of amounts due from government agencies, not-for-profit providers and commercial insurance companies. An estimated allowance for doubtful accounts is recorded to the extent it is probable that a portion or all of a particular account will not be collected. In evaluating the collectability of accounts receivable, the Company considers a number of factors, including payment trends in individual states, age of the accounts and the status of ongoing disputes with third party payors. Complex rules and regulations regarding billing and timely filing requirements in various states are also a factor in our assessment of the collectability of accounts receivable. Actual collections of accounts receivable in subsequent periods may require changes in the estimated allowance for doubtful accounts. Changes in these estimates are charged or credited to revenue as a contractual allowance in the consolidated statements of income in the period of the change in estimate. Goodwill and Indefinite-lived Intangible Assets The Company reviews costs of purchased businesses in excess of the fair value of net assets acquired (goodwill), and indefinite-lived intangible assets for impairment at least annually, unless significant changes in circumstances indicate a potential impairment may have occurred sooner. The Company conducts its annual impairment test for both goodwill and indefinite-lived intangible assets on July 1 st of each year. In fiscal 2016, the Company conducted the goodwill impairment test on a reporting unit basis using the two step process in accordance with the guidance in ASC 350. The Company had the option to first assess qualitative factors to determine whether further impairment testing is necessary. The Company elected to bypass the qualitative assessments and proceeded directly to the two-step impairment test. The first step is to compare the fair value of the reporting unit with its carrying value. The fair value of the reporting unit is determined by using the income approach, specifically the discounted cash flow method. If the carrying amount of the reporting unit exceeds its fair value then the second step of the goodwill impairment test is performed. The second step of the goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill in order to determine the amount of impairment to be recognized. The excess of the carrying value of goodwill above the implied goodwill, if any, would be recognized as an impairment charge. Fair values are estimated using the discounted cash flow method. Beginning in fiscal 2017, the Company no longer performs Step 2 of the goodwill impairment test. The annual impairment tests in fiscal 2017 and fiscal 2018 were performed by comparing the fair value of a reporting unit with its carrying value. The fair value of the reporting unit is determined by using the income approach, specifically the discounted cash flow method, and corroborated by the market approach. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value, an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. For its indefinite-lived intangible assets, the Company has elected to bypass the qualitative assessments and proceed directly to the quantitative impairment test. The impairment test for indefinite-lived intangible assets requires the determination of the fair value of the intangible asset. If the fair value of the indefinite-lived intangible asset is less than its carrying value, an impairment loss is recognized in an amount equal to the difference. Fair values are estimated using the relief from royalty method. As described above, the fair value of a reporting unit and intangible asset is based on discounted estimated future cash flows. The assumptions used to estimate fair value include management’s best estimates of future operating cash flows, including revenue growth, tax rates, capital expenditures, discount rates and working capital changes. As such, actual results may differ from these estimates and lead to a revaluation of the Company’s goodwill and indefinite-lived intangible assets. Impairment of Long-Lived Tangible and Intangible Assets The Company reviews long-lived tangible and intangible assets for impairment when events or circumstances have occurred that indicate the estimated useful life of these assets may warrant revision or that the carrying amount of these assets may be impaired. To compute whether assets have been impaired, the estimated undiscounted future cash flows for the estimated remaining useful life of the assets are compared to the carrying value. To the extent that the future cash flows are less than the carrying value, the assets are written down to the estimated fair value of the asset. Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are determined by multiplying the differences between the financial reporting and tax reporting bases for assets and liabilities by the enacted tax rates expected to be in effect when such differences are recovered or settled. Valuation allowances on deferred tax assets are estimated based on the Company’s assessment of the realizability of such amounts. The Company recognizes the benefits of tax positions when certain criteria are satisfied. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense. Derivative Financial Instruments The Company reports derivative financial instruments on the balance sheet at fair value and establishes criteria for designation and effectiveness of hedging relationships. Changes in the fair value of derivatives are recorded each period in current operations or in the consolidated statements of comprehensive income (loss) depending upon whether the derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. The Company, from time to time, enters into interest rate swap agreements to hedge against variability in cash flows resulting from fluctuations in the benchmark interest rate, which is LIBOR, on the Company’s debt. These agreements involve the exchange of variable interest rates for fixed interest rates over the life of the swap agreement without an exchange of the notional amount upon which the payments are based. On a quarterly basis, the differential to be received or paid as interest rates change is accrued and recognized as an adjustment to interest expense in the accompanying consolidated statements of income. In addition, on a quarterly basis, the mark to market valuation is recorded as an adjustment to gain (loss) on derivative within the consolidated statements of comprehensive income with any ineffective portion recorded to Interest expense within the consolidated statement of income. The related amount receivable from or payable to counterparties is included as an asset or liability, respectively, in the Company’s consolidated balance sheets. Stock-Based Compensation Prior to the Company's initial public offering ("IPO"), NMH Investment maintained an equity-based compensation plan, and from time to time it issued units of limited liability company interests pursuant to such plan. The units were available for issuance to the Company’s employees and members of the Board of Directors. The Company recognized the fair value of these awards as compensation expense over the requisite services period or when the satisfaction of the vesting conditions were determined to be probable. In October 2015, NMH Investment distributed all of the 25,250,000 shares of our common stock it held to its existing members in accordance with their respective membership interests and pursuant to the terms of the NMH Investment's Limited Liability Company Agreement and the management unitholders agreements (the “Distribution”). The Distribution triggered the vesting conditions for all unvested awards. As a result, the Company recorded compensation expense of $10.5 million that is included in General and administrative expense on the consolidated statement of income during the year ended September 30, 2016. In fiscal 2014, Civitas adopted an equity-based compensation plan and began issuing stock-based awards including non-qualified stock options ("NSOs"), restricted stock units ("RSUs"), and performance based restricted stock units ("PRSUs"). The Company recognizes the fair value of stock-based compensation expense over the requisite service period of the individual grantee, which equals the vesting period. The fair value of each NSO granted was estimated on the grant date using the Black-Scholes valuation model. The fair value of each RSU was determined based on the Company's closing stock price on the date of grant. The fair value of each PRSU was determined based on either the Company's closing stock price on the date of grant or through a Monte Carlo simulation methodology for those awards that included a market condition. The number of performance based restricted stock units earned is determined based on the Company's attainment of predefined performance targets set by the Compensation Committee. At each reporting period, the Company assesses the number of performance based restricted stock units expected to vest based on the expected attainment of the performance targets. The Company recognizes forfeitures as they occur. The actual expense recognized over the vesting period will only be for those awards that vest. Self-Insurance The Company maintains insurance for professional and general liability, workers’ compensation, automobile liability and health insurance with policies that include self-insured retentions. Employment practices liability is fully self-insured. The Company records expenses related to claims on an incurred basis, which includes estimates of fully developed losses for both reported and unreported claims. The accruals for the health, workers’ compensation, automobile, employment practices liability and professional and general liability programs are based on analyses performed internally by management and for certain balances, take into account reports by independent third party actuaries. Self-insurance accruals are periodically re-evaluated and increased or decreased based on new information. The Company reports its insurance liabilities on a gross basis without giving effect to insurance recoveries. Insurance recovery receivables are presented in Prepaid expenses and other current assets and Other assets on the consolidated balance sheets. Self-insured liabilities are presented in Accrued payroll and related costs, Other accrued liabilities and Other long-term liabilities on the Company’s consolidated balance sheets. Legal Contingencies The Company reserves for costs related to contingencies when a loss is probable and the amount is reasonably estimable or a range of loss can be determined. These accruals represent management’s best estimate of probable loss. Disclosure is also provided when it is reasonably possible that a loss will be incurred or when it is reasonably possible that the amount of loss will exceed the recorded provision. Significant judgment is required in both the determination of probability and the determination as to whether an exposure is reasonably estimable. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, the Company reassesses the potential liability related to pending claims and litigation and may revise its estimates. These revisions in the estimates of the potential liabilities could have a material impact on our consolidated results of operations and financial position. Leases The Company accounts for leases in accordance with ASC Topic 840 Leases . For lease agreements that provide for escalating rent payments and rent holidays, the Company recognizes rent expense on a straight-line basis over the non-cancellable lease term and option renewal periods where failure to exercise such options would result in an economic penalty such that the renewal appears, at the inception of the lease, to be reasonably assured. The lease term commences when the Company becomes obligated under the terms of the lease agreement. Subsequent Events The Company considers events or transactions that have occurred after the balance sheet date of September 30, 2018 , but prior to the filing of the financial statements with the Securities and Exchange Commission, or SEC, to provide additional evidence relative to certain estimates or to identify matters that require additional recognition or disclosure. Subsequent events have been evaluated through the filing of the financial statements accompanying this Annual Report on Form 10-K.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Revenue from Contracts with Customers— In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers Topic 606 (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The FASB has subsequently issued amendments to ASU No. 2014-09 that have the same effective date and transition date. ASU 2014-09, as amended, is effective for the Company's fiscal year beginning October 1, 2018, and the Company will adopt the new standard under the modified retrospective approach for contracts with customers. Under the modified retrospective approach, the guidance will be applied to the most current period presented, recognizing the cumulative effect of the adoption change as an adjustment to beginning retained earnings. In fiscal 2017, the Company established a formal program and cross-functional implementation team to identify design and implement changes to its accounting systems and policies and internal controls to support recognition and disclosure under the new standard. This process included a review of the requirements under the new standard compared to the current accounting policies for each of the Company’s revenue streams. As of the end of the fourth quarter, the Company completed its review and there is not expected to be a material impact on the consolidated financial statements upon implementation on October 1, 2018. The Company has implemented changes to accounting policies and controls to support the new revenue recognition and disclosure requirements. Leases— In February 2016, the FASB issued ASU No. 2016-02—Leases (Topic 842). The new standard requires that all lessees recognize the assets and liabilities that arise from leases on the balance sheet and disclose qualitative and quantitative information about its leasing arrangements. The standard will be effective for the Company on October 1, 2019. In July 2018, the FASB issued ASU No. 2018-11— Leases (Topic 842): Targeted Improvements (ASU 2018-11). Prior to ASU 2018-11, a modified retrospective transition was required for financing or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements. ASU 2018-11 allows entities an additional transition method to the existing requirements whereby an entity could adopt the provisions of ASU 2016-02 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without adjustment to the financial statements for periods prior to adoption. The Company will elect this new transition method when it adopts ASU 2016-02 on October 1, 2019. The adoption of this standard is expected to have a material impact on the Company's financial position. As of September 30, 2018 and September 30, 2017 , the Company had gross operating lease commitments of approximately $374 million and $317 million , respectively. Upon adoption, a substantial portion of these lease commitments will be recorded at their net present value as a right of use asset and a lease obligation. Statement of Cash Flows — In November 2016, the FASB issued ASU No. 2016-18— Statement of Cash Flows (Topic 230): Restricted Cash . The update requires that a statement of cash flows present the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new standard is effective for the Company on October 1, 2018 and will be applied using a retrospective transition method by adjusting the prior periods presented to conform to the new presentation. As of September 30, 2018 and 2017, the Company had restricted cash amounts of $50.3 million . Business Combinations — In January 2017, the FASB issued ASU No. 2017-01— Business Combinations (Topic 805): Clarifying the Definition of a Business . The update provides guidance to determine when an integrated set of assets and activities is not a business. When substantially all of the fair value of the gross assets acquired, or disposed of, is concentrated in a single identifiable asset or a group of similar identifiable assets, then the acquisition, or disposition, is not a business. The amendments in this update should be applied prospectively on or after the effective date. No disclosures are required at transition. The new standard is effective for the Company on October 1, 2018. This standard could reduce the number of acquisitions that are treated as business combinations in the future. Fair Value Measurements — In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement , which is designed to improve the effectiveness of disclosures by removing, modifying and adding disclosures related to fair value measurements. The update is effective for the Company on October 1, 2020, with early adoption permitted. The Company is currently assessing the impact this update will have on its consolidated financial statements. Cloud Computing Arrangements — In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract . The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this update. The amendments in this update are effective for the Company on October 1, 2020, with early adoption permitted. The amendments in this update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is in the process of assessing the impact of the amendments in this update but does not expect it to have a material impact on the Company's consolidated financial statements.

Discontinued Operations and Disposal Groups [Abstract]
Dispositions	Dispositions In connection with a review of under-performing and/or non-strategic programs that began during the second quarter of fiscal 2018, the Company decided to close and/or consolidate a number of programs primarily within the SRS and CSS segments. During the year ended September 30, 2018 , the Company incurred exit costs associated with these completed and planned divestitures of $10.7 million , including $10.0 million in lease termination costs, and $0.7 million in severance. In addition, the Company recorded $6.1 million of accelerated amortization related to definite-lived intangible assets and a $1.2 million loss on the disposition of fixed assets associated with these programs. As part of a strategic review of CFS operations, the Company decided to discontinue CFS services in the states of Florida, Louisiana, Indiana, North Carolina and Texas in fiscal 2015. These operations were included in the CFS segment. On December 1, 2015, the Company completed the sale of its CFS operations in the state of North Carolina. As consideration, the buyer assumed the lease and service delivery obligations in exchange for the assets of the business, excluding working capital items, and a cash payment of $1.3 million to the buyer. Upon the completion of the sale, the Company recorded a loss of $1.3 million . The closures of the CFS operations in Florida and Louisiana were complete as of December 31, 2015 and the closures of CFS operations in Indiana and Texas were completed in January 2016. During fiscal 2016, the Company recorded cash charges of approximately $2.0 million , consisting of severance costs of $0.5 million and lease termination costs of $1.5 million . For the CFS services that were discontinued in fiscal 2015, the Company assessed the disposal group under the guidance of ASU 2014-08, Discontinued Operations and Disclosures of Disposals of Components of an Entity and concluded that the closure of the disposal group does not represent a "strategic shift" and therefore has not been classified as discontinued operations for any of the periods presented. However, the Company has concluded that the disposal group was an individually significant disposal group. There were no operating results for the disposal group during the years ended September 30, 2018 and September 30, 2017. Pretax losses for this disposal group were $5.6 million for the fiscal year ended September 30, 2016. Pretax losses for the year ended September 30, 2016 included exit costs of $2.0 million disclosed above.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill The Company has three reportable business segments: the CSS segment, the SRS segment and the CFS segment. The ADH operating segment is included in Corporate and Other. For more information refer to Note 19, "Segment Information." The changes in goodwill for the fiscal years ended September 30, 2018 and 2017 are as follows (in thousands): CSS SRS CFS Corporate/Other Total Balance as of September 30, 2016 $ 104,155 $ 81,909 $ 73,464 $ 14,132 $ 273,660 Impact of segment change 44,980 — (44,980 ) — — Acquisition adjustments (17 ) — — 10 (7 ) Goodwill acquired through acquisitions 10,198 3,616 — 13,827 27,641 Impairment — — — (27,969 ) (27,969 ) Balance as of September 30, 2017 159,316 85,525 28,484 — 273,325 Goodwill acquired through acquisitions 508 31,920 — 4,105 36,533 Adjustments to prior acquisitions (1) 1,894 — — — 1,894 Balance as of September 30, 2018 $ 161,718 $ 117,445 $ 28,484 $ 4,105 $ 311,752 (1) Includes amounts paid in fiscal 2018 associated with the net working capital settlement for the HSI acquisition in fiscal 2017. As a result of segment and reporting unit changes that were effective as of October 1, 2016, the Company allocated goodwill between the new CSS and CFS reporting units based on the relative fair values, resulting in an allocation of $45.0 million . The Company estimated the fair value of the new reporting units using the income approach. The income approach is based on a discounted cash flow analysis and calculates the fair value of a reporting unit by estimating the after–tax cash flows attributable to a reporting unit and then discounting them to a present value using a risk-adjusted discount rate. In the discounted cash flow analysis, cash flows for the new reporting units were forecasted for each of the next ten years and a long term growth rate was applied to the final year of the forecasted cash flows to estimate terminal value. The cash flows were then discounted to a present value using a risk-adjusted discount rate. The discount rates, which are intended to reflect the risks inherent in future cash flow projections used in the discounted cash flow analysis, are based on estimates of the weighted average costs of capital of market participants relative to each respective reporting unit. This change in the Company's CSS and CFS reporting units was considered a triggering event that indicated a test for goodwill impairment was necessary as of October 1, 2016. The Company completed impairment tests for these reporting units as of October 1, 2016 and it was determined that the carrying value of goodwill was not impaired as the fair value of the reporting units significantly exceeded the carrying value. Annual Goodwill Impairment Testing The Company completes the annual testing of impairment for goodwill on July 1st of each fiscal year. In addition to its annual test, the Company regularly evaluates whether events or circumstances have occurred that may indicate a potential impairment of these assets. The Company utilizes the income approach, specifically the discounted cash flow method, to estimate the fair value of its reporting units when testing for impairment of goodwill. A number of significant assumptions and estimates are involved in the application of the income approach to forecast operating cash flows, including revenue growth, capital spending, discount rate and working capital changes. These inputs are not observable in the market and represent Level 3 inputs within the fair value hierarchy. Cash flow forecasts are based on business unit operating plans and historical experiences. The income approach is sensitive to changes in long-term terminal growth rates and the discount rate. The discount rate was selected based on the estimated rate of return as well as the time value of money. The Company conducted Step 1of the annual goodwill impairment test as of July 1, 2018, which indicated that the fair value of each reporting unit exceeded its carrying value. For the annual goodwill impairment test as of July 1, 2017, Step 1 indicated that the fair value of the ADH reporting unit, that is included within Corporate and Other, was less than its carrying value. Based on the guidance in ASU 2017-04, the Company recognized an impairment charge for the amount by which the carrying amount exceeded the reporting unit’s fair value. The $28.0 million impairment charge is included in Goodwill and intangible asset impairment in the consolidated statement of income for the year ended September 30, 2017. The goodwill impairment was attributable to a reduction in the profit projections of the core ADH business and a decrease in the forecasted contributions from future new start programs as compared to the prior year's projections. Prior to adoption of ASU 2017-04, our annual impairment analysis as of July 1, 2016 indicated that the Step 2 analysis was necessary for the ADH reporting unit, that is included within Corporate/Other, as the carrying value exceeded the fair value of the reporting unit. Step 2 of the goodwill test is performed to measure the impairment loss. Step 2 required that the implied fair value of the reporting unit goodwill be compared to the carrying amount of that goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. After performing Step 2, it was determined that the implied value of goodwill was less than the carrying amount, resulting in an impairment charge of $10.3 million that is included in Goodwill and intangible asset impairment in the consolidated statement of income for the year ended September 30, 2016. The impairment was driven by higher than anticipated operating costs in recently acquired businesses that have negatively affected the reporting unit's projected operating margins. The Company completed Step 1 for its other reporting units as of July 1, 2017 and 2016 and concluded that there was no goodwill impairment. Intangible Assets Intangible assets consist of the following as of September 30, 2018 (in thousands): Description Weighted Average Remaining Life Gross Carrying Value Accumulated Amortization Intangible Assets, Net Agency contracts 6 years $ 581,222 $ 326,925 $ 254,297 Non-compete/non-solicit 1 year 7,453 5,974 $ 1,479 Trade names 1 year 8,161 6,771 $ 1,390 Trade names (indefinite life) — 42,400 — $ 42,400 Licenses and permits 3 years 62,279 44,673 $ 17,606 $ 701,515 $ 384,343 $ 317,172 Intangible assets consist of the following as of September 30, 2017 (in thousands): Description Weighted Average Remaining Life Gross Carrying Value Accumulated Amortization Intangible Assets, Net Agency contracts 7 years $ 540,826 $ 290,687 $ 250,139 Non-compete/non-solicit 1 year 7,196 5,228 1,968 Trade names 2 years 7,138 4,779 2,359 Trade names (indefinite life) — 42,400 — 42,400 Licenses and permits 3 years 58,443 42,234 16,209 $ 656,003 $ 342,928 $ 313,075 For fiscal years ended 2018 , 2017 and 2016 , the amortization expense for continuing operations was $50.7 million , $37.0 million and $38.1 million , respectively. Amortization expense for the year ended September 30, 2018 includes $6.1 million of accelerated amortization related to definite-lived intangible assets associated with the divestitures described in Note 6. Indefinite Life Impairment Testing The Company tests indefinite-lived intangible assets at least annually for possible impairment. Accordingly, the Company completes the annual testing of impairment for indefinite-lived intangible assets on July 1 of each fiscal year. In addition to its annual test, the Company regularly evaluates whether events or circumstances have occurred that may indicate a potential impairment of these assets. The impairment test consists of a comparison of the fair value of the indefinite-lived intangible asset with its carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss in an amount equal to that excess is recognized. The Company has consistently employed the relief from royalty model to estimate the current fair value when testing for impairment of indefinite-lived intangible assets. In addition, the Company evaluates the remaining useful life of its indefinite-lived intangible assets at least each reporting period to determine whether events or circumstances continue to support an indefinite useful life. If events or circumstances indicate that the useful lives of indefinite-lived intangible assets are no longer indefinite, the assets will be tested for impairment. The Company performed its annual impairment testing as of July 1, 2018 , 2017 and 2016 and concluded that there is no impairment to its indefinite lived trade names. During the fourth quarter of fiscal 2017, the Company concluded that the useful lives of the indefinite-lived ADH trade names are no longer indefinite as a result of the Company's decision to phase in one national brand name for this business. The Company performed an impairment test using the relief from royalty model over the remaining useful life of one year. The impairment test indicated that the $3.4 million carrying value of the indefinite-lived ADH trade names exceeded its fair value, resulting in an impairment charge of $3.0 million which is included in Goodwill and intangible asset impairment in the consolidated statement of income for the year ended September 30, 2017. The remaining net book value of $0.4 million was amortized over the remaining useful life of one year, and the ADH trade names are fully amortized as of September 30, 2018. Long-Lived Asset Impairment Testing The Company reviews long-lived tangible and intangible assets for impairment when events or circumstances have occurred that indicate the estimated useful life of these assets may warrant revision or that the carrying amount of these assets may be impaired. During the fiscal year ended September 30, 2018, the Company concluded that there were no triggering events associated with long-lived assets, except for the divestitures described in Note 6. The Company performed a test of recoverability, which indicated that the carrying value of the associated assets was no longer recoverable. As a result, the Company recorded $6.1 million of accelerated amortization related to definite-lived intangible assets and a $1.2 million loss on the disposition of fixed assets associated with these programs. During the fiscal years ended September 30, 2017 and 2016, the Company concluded it had a triggering event requiring assessment of impairment for certain long-lived assets held by ADH due to the impairment of goodwill. The Company estimated the future net undiscounted cash flows and compared them to the carrying amount of the assets. Based on this assessment the Company concluded that the assets are recoverable as the undiscounted cash flows exceeded the carrying amount, therefore; an impairment did not exist at September 30, 2017 and 2016. The estimated remaining amortization expense related to intangible assets with finite lives for each of the five succeeding years and thereafter is as follows: Year Ending September 30, (In thousands) 2019 $ 44,022 2020 42,580 2021 39,165 2022 37,360 2023 33,019 Thereafter 78,626 $ 274,772

Senior Secured Credit Facilities As of September 30, 2018, NMHI's senior credit agreement (the “senior credit agreement”), as amended, governs a $730.0 million Tranche B term loan facility (the “term loan facility”), of which $50.0 million was deposited in a cash collateral account in support of the issuance of letters of credit under an institutional letter of credit facility (the “institutional letter of credit facility”), and a $160.0 million senior secured revolving credit facility (the “senior revolver”). The term loan facility matures on January 31, 2021 a portion of the commitments under the senior revolver matures on January 31, 2019 and a portion of the commitments under the senior revolver matures on January 31, 2021, as described below. All of the obligations under the senior secured credit facilities are guaranteed by NMHH and the subsidiary guarantors named therein. The senior credit agreement provides that NMHI may make one or more offers to the lenders, and consummate transactions with individual lenders that accept the terms contained in such offers, to extend the maturity date of the lender’s term loans and/or revolving commitments, subject to certain conditions, and any extended term loans or revolving commitments will constitute a separate class of term loans or revolving commitments. On October 24, 2017, NMHI entered into Amendment No. 6 to its senior credit agreement which provided for an incremental $75.0 million term loan. The net proceeds of the incremental term loan were used by the Company for the acquisition of Mentis, with any excess proceeds used for general corporate purposes. On November 21, 2017, NMHI entered into Amendment No. 7 to its senior credit agreement which increased the aggregate revolving commitments from $120.0 million to $160.0 million and extended the maturity date for $90.0 million of the revolving commitments (the “Extended Revolving Commitments") to January 31, 2021. The terms of the remaining $70.0 million of the revolving commitments (the "Initial Revolving Commitments"), which mature on January 31, 2019, remain unchanged. All of the other terms of the Extended Revolving Commitments are identical to the Initial Revolving Commitments, except that the applicable margin for the Extended Revolving Commitments will decrease by 0.25% per annum when the Initial Revolving Commitments are terminated or expire. The senior revolver includes borrowing capacity available for letters of credit and for borrowings on same-day notice, referred to as the “swingline loans.” Any issuance of letters of credit or borrowing on a swingline loan will reduce the amount available under the senior revolver. As of September 30, 2018 , NMHI had no borrowings under the senior revolver, $48.5 million of letters of credit issued under the institutional letter of credit facility and $2.9 million of standby letters of credit under the senior revolver. On May 25, 2017, NMHI entered into Amendment No. 5 to its senior credit agreement (the "repricing amendment"). Under the terms of the repricing amendment, the applicable interest margin for the term loan facility under the senior credit agreement decreased by 25 basis points for both alternate base rate ("ABR") borrowings and Eurodollar borrowings, and reduced the Eurodollar floor by 25 basis points. The repricing amendment also reset the period during which a 1.0% prepayment premium may be required for a repricing transaction (as defined in the senior credit agreement) until May 25, 2018. As a result of the repricing amendment, borrowings under the term loan facility bear interest, at our option, at: (i) an alternate base rate ("ABR") equal to the greater of (a) the prime rate of Barclays Bank PLC, (b) the federal funds rate plus 1/2 of 1.0% , and (c) the Eurodollar rate for an interest period of one-month plus 100 basis points (provided that the ABR applicable to the term loan facility will not be less than 2.00% per annum), plus 2.00% ; or (ii) the Eurodollar rate (provided that the Eurodollar rate applicable to the term loan facility will not be less than 0.75% per annum), plus 3.00% . Borrowings under the revolving and swingline loans bear interest at our option at (i) an alternate base rate equal to the greater of (a) the prime rate of Barclays Bank PLC, (b) the federal funds rate plus 1/2 of 1.0% , and (c) the Eurodollar rate for an interest period of one-month plus 100 basis points (provided that the ABR applicable to the term loan facility will not be less than 2.00% per annum), plus 2.25% ; or (ii) the Eurodollar rate (provided that the Eurodollar rate applicable to the term loan facility will not be less than 0.75% per annum), plus 3.25% . NMHI is also required to pay a commitment fee to the lenders under the senior revolver at an initial rate of 0.50% of the average daily unutilized commitments thereunder. NMHI must also pay customary letter of credit fees. The senior credit agreement requires NMHI to make mandatory prepayments, subject to certain exceptions, on a percentage of NMHI's annual Excess Cash Flow, as defined in the senior credit agreement. NMHI determines whether or not a mandatory prepayment is required at the end of each fiscal year. NMHI was not required to make a prepayment for the fiscal year ended September 30, 2018 . Covenants The senior credit agreement contains negative covenants, including, among other things, limitations on the Company’s ability to incur additional debt, create liens on assets, transfer or sell assets, pay dividends, redeem stock or make other distributions or investments, and engage in certain transactions with affiliates. The senior credit agreement contains a springing financial covenant. If, at the end of any fiscal quarter, the Company’s outstanding borrowings under the senior revolver exceeds 30% of the commitments thereunder, it is required to maintain at the end of each such fiscal quarter a consolidated first lien leverage ratio of not more than 5.00 to 1.00. The springing financial covenant was not in effect as of September 30, 2018 as our usage of the senior revolver did not exceed the threshold for that quarter. Derivatives On January 20, 2015, NMHI entered into two interest rate swap agreements in an aggregate notional amount of $375.0 million in order to reduce the variability of cash flows of our variable rate debt. NMHI entered into these interest rate swaps to hedge the risk of changes in the floating rate of interest on borrowings under the term loan. Under the terms of the swaps, NMHI will receive from the counterparty a quarterly payment based on a rate equal to the greater of 3-month LIBOR or 1.00% per annum, and NMHI will make payments to the counterparty based on a fixed rate of 1.795% per annum, in each case on the notional amount of $375.0 million , settled on a net payment basis. The swap agreements expire on March 31, 2020. The fair value of the swap agreements, representing the price that would be received to transfer the liability in an orderly transaction between market participants, was an asset of $5.8 million at September 30, 2018 and a liability of $0.2 million at September 30, 2017 . Based on the timing of the associated cash flows, the fair value was split between current and long-term classification on the Company’s consolidated balance sheet in Prepaid expenses and other current assets and Other assets as of September 30, 2018 and in Other accrued liabilities as of September 30, 2017 . The fair value was determined based on pricing models and independent formulas using current assumptions. Hedge ineffectiveness, if any, associated with the swap is recorded as interest expense in the period incurred. During the year ended September 30, 2018, the ineffective portion of gains resulting from changes in fair value was $0.3 million which was recorded in Interest expense in the consolidated statement of income. The Company did not record any interest expense for ineffectiveness during the years ended September 30, 2017 and 2016. No amounts were excluded from ineffectiveness testing for the years ended September 30, 2018, 2017, and 2016. Annual maturities Annual maturities of the Company’s debt for the fiscal year ended September 30 are as follows: (In thousands) 2019 $ 7,331 2020 7,331 2021 685,483 Total $ 700,145 Amounts due at any year end may increase as a result of the provision in the senior credit agreement that requires a prepayment of a portion of the outstanding term loan amount if NMHI generates certain levels of cash flow.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company measures and reports its financial assets and liabilities on the basis of fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques for assets and liabilities measured using Level 3 inputs may include methodologies such as the market approach, the income approach or the cost approach, and may use unobservable inputs such as projections, estimates and management’s interpretation of current market data. These unobservable inputs are only utilized to the extent that observable inputs are not available or cost-effective to obtain. A description of the valuation methodologies used for instruments measured at fair value as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. The following table set forth the Company’s assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2018 . (in thousands) Total Quoted Market Prices (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Interest rate swap agreements (current) $ 3,447 $ — $ 3,447 $ — Interest rate swap agreements (long-term) 2,320 — 2,320 — Total $ 5,767 $ — $ 5,767 $ — Liabilities Contingent consideration $ 1,805 $ — $ — $ 1,805 The following table set forth the Company’s assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2017 . (in thousands) Total Quoted Market Prices (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Liabilities Interest rate swap agreements $ (153 ) $ — $ (153 ) $ — Interest rate-swap agreements. The Company’s interest rate swap agreements are classified within level 2 of the fair value hierarchy. Based on the timing of the associated cash flows, the fair value of the swap agreements was recorded in Prepaid expenses and other current assets, Other assets, or Other accrued liabilities in the Company’s consolidated balance sheets. The fair value of these agreements was determined based on pricing models and independent formulas using current assumptions that included swap terms, interest rates and forward LIBOR curves and the Company’s credit risk. Contingent Consideration. In connection with the acquisitions of Powell, Jac-Lin, and CCI in fiscal 2018, the Company recorded contingent consideration pertaining to the amounts potentially payable to the former owners upon the businesses achieving certain performance targets. The fair values of the Company's contingent consideration obligations were based on a probability-weighted approach derived from the overall likelihood of achieving certain performance targets. The fair value measurement was based on significant inputs not observable in the market, which represent Level 3 inputs within the fair value hierarchy. The following table presents a summary of changes in fair value of the Company’s Level 3 liabilities measured on a recurring basis for fiscal years 2018 and 2017 . (in thousands) Level 3 Inputs Liabilities Balance at September 30, 2016 $ 5,915 Fair value adjustments 194 Payments (1) (6,109 ) Balance at September 30, 2017 — Acquisition date fair value of contingent consideration obligations recorded 1,805 Balance at September 30, 2018 $ 1,805 (1) The Company settled the remaining Adult Day Health and Cassell contingent consideration obligations during the year ended September 30, 2017 for $6.1 million . As of September 30, 2018 , the Company had $1.8 million of contingent consideration liabilities, which was reflected in Other accrued liabilities or Other long-term liabilities. As of September 30, 2017 , the Company had no contingent consideration liability. Items Measured at Fair Value on a Nonrecurring Basis. The Company’s intangible assets are measured at fair value on a nonrecurring basis using Level 3 inputs. During the year ended September 30, 2017, the Company recorded a $3.0 million impairment charge associated with the indefinite-lived ADH trade names due to the Company's decision to phase in one national brand name for its ADH business unit. See Note 7 for further information about the impairment charge which was recorded in Goodwill and intangible asset impairment in the consolidated statement of income. The impairment charge was determined by comparing the fair value based on the relief from royalty model over the remaining useful life of one year to the assets' carrying value of $3.4 million . There were no other items measured at fair value on a nonrecurring basis during the years ended September 30, 2018, 2017 or 2016. At September 30, 2018 and 2017, the carrying values of cash, accounts receivable, accounts payable and variable rate debt approximated fair value.

Commitments and Contingencies Disclosure [Abstract]
Accruals for Self-Insurance	Accruals for Self-Insurance The Company maintains insurance for professional and general liability, workers’ compensation liability, automobile liability and health insurance liabilities that includes self-insured retentions. The Company intends to maintain such coverage in the future and is of the opinion that its insurance coverage is adequate to cover potential losses on asserted claims. Employment practices liability is fully self-insured. The Company records expenses related to claims on an incurred basis, which includes estimates of fully developed losses for both reported and unreported claims. The accruals for the health, workers’ compensation, automobile, and professional and general liability programs are based on analyses performed by management and take into account reports by independent third parties. Accruals are periodically reevaluated and increased or decreased based on new information. The expense related to professional and general liability for the fiscal years ended September 30, 2018 , 2017 and 2016 was $13.5 million , $7.2 million and $12.9 million , respectively. The expense related to employment practices liability for the fiscal years ended September 30, 2018 , 2017 and 2016 was $2.2 million , $5.5 million , and $0.2 million , respectively. For professional and general liability, the Company is self-insured for $3.0 million per claim and $28.0 million in the aggregate. For workers’ compensation, the Company has a $350 thousand per claim retention with statutory limits. Automobile liability has a $100 thousand per claim retention, with additional insurance coverage above the retention.

Commitments and Contingencies Disclosure [Abstract]
Other Commitments and Contingencies	Other Commitments and Contingencies The Company is in the health and human services business and, therefore, has been and continues to be subject to numerous claims alleging that the Company, its employees or its independently contracted host-home caregivers (“Mentors”) failed to provide proper care for an individual served by the Company. The Company is also subject to claims by these individuals, its employees, its Mentors or community members against the Company for negligence, intentional misconduct or violation of applicable laws. Included in the Company’s recent claims are claims alleging personal injury, assault, abuse, wrongful death, violations of wage and hour laws and other charges. Regulatory agencies may initiate administrative proceedings alleging that the Company’s programs, employees or agents violate statutes and regulations and seek to impose monetary penalties on the Company. The Company could be required to incur significant costs to respond to regulatory investigations or defend against civil lawsuits and, if the Company does not prevail, the Company could be required to pay substantial amounts of money in damages, settlement amounts or penalties arising from these legal proceedings. The Company is also subject to potential lawsuits under the False Claims Act and other federal and state whistleblower statutes designed to combat fraud and abuse in the health care industry. These lawsuits can involve significant monetary awards that may incentivize private plaintiffs to bring these suits. If the Company is found to have violated the False Claims Act, it could be excluded from participation in Medicaid and other federal healthcare programs which would have a material adverse effect on our business. The Patient Protection and Affordable Care Act provides a mandate for more vigorous and widespread enforcement activity to combat fraud and abuse in the health care industry. The Company is also subject to employee-related claims under state and federal law, including claims for wage and hour violations under the Fair Labor Standards Act or state wage and hour laws, and claims for discrimination, wrongful discharge or retaliation. The Company currently has two pending complaints in California state court that allege certain wage and hour violations of California labor laws and seek to be designated as class-actions. Two additional wage and hour complaints have been settled and approved by the court. The Company's policy is to accrue for all probable and estimable claims using information available at the time the financial statements are issued. Actual claims could settle in the future at materially different amounts due to the nature of litigation.

Income Taxes	Income Taxes The provision (benefit) for income taxes consists of the following as of September 30 (in thousands): 2018 2017 2016 Current: Federal $ 7,572 $ 18,701 $ 5,382 State 3,788 5,708 3,549 Total current tax provision 11,360 24,409 8,931 Deferred: Federal (10,128 ) (17,894 ) 4,701 State (1,836 ) (4,651 ) (342 ) Net deferred tax provision (benefit) (11,964 ) (22,545 ) 4,359 Income tax provision (benefit) $ (604 ) $ 1,864 $ 13,290 On December 22, 2017, the Tax Cuts and Jobs Act (the "Tax Act") was enacted into law in the United States. The Tax Act significantly revises corporate income tax law by, among other things, lowering the corporate income tax rates from 35% to 21%. Under GAAP, deferred taxes must be adjusted for enacted changes in tax laws or rates during the period in which new tax legislation is enacted. During the year ended September 30, 2018, a tax benefit of approximately $4.9 million was recorded, representing the revaluation of deferred tax assets and liabilities as a result of the lower corporate tax rate established by the Tax Act. As of September 30, 2018, the Company has completed the accounting for the tax effects of the enactment of the Tax Act. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of the assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities consist of the following as of September 30 (in thousands): 2018 2017 Gross deferred tax assets: Deferred compensation $ 869 $ 1,300 Interest rate swap agreements — 62 Accrued workers’ compensation 7,414 11,147 Net operating loss carryforwards 10,188 6,215 Allowance for bad debts 6,317 6,398 Stock compensation 3,225 3,353 Other accrued liabilities 10,040 9,634 38,053 38,109 Valuation allowance (7,859 ) (6,215 ) Deferred tax assets 30,194 31,894 Deferred tax liabilities: Interest rate swap agreements (1,501 ) — Depreciation (4,610 ) (1,596 ) Amortization of goodwill and intangible assets (32,205 ) (52,647 ) Net deferred tax liabilities $ (8,122 ) $ (22,349 ) The Company is required to record a valuation allowance to reduce the deferred tax assets if, based on the weight of the evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. After consideration of all the evidence, both positive and negative, management determined that valuation allowances at September 30, 2018 and 2017 of $7.9 million and $6.2 million , respectively, were necessary to reduce the deferred tax assets to the amount that will more likely than not be realized. The valuation allowances primarily related to certain state net operating loss carryforwards. For federal purposes, the Company had $11.1 million net operating loss carryforwards as of September 30, 2018 . For state purposes, the Company had $145.6 million of net operating loss carryforwards for fiscal 2018 , which expire from 2018 through 2038. The following is reconciliation between the statutory and effective income tax rates at September 30 (in thousands): 2018 2017 2016 Federal income tax at statutory rate 24.5 % 35.0 % 35.0 % State income taxes, net of federal tax benefit 10.3 % 8.5 % 9.3 % Nondeductible compensation (1) 4.1 % 7.9 % 18.8 % Other nondeductible expenses 1.4 % (0.4 )% 1.5 % Credits (16.9 )% (22.5 )% (6.6 )% Impacts of the Tax Act (2) (34.4 )% 0.0 % 0.0 % Other 6.8 % (5.8 )% 0.4 % Effective tax rate (4.2 )% 22.7 % 58.4 % (1) The higher impact on the effective rate for fiscal 2016 was due to a stock compensation charge of $10.5 million recorded in the first quarter of fiscal 2016 related to certain awards under our former equity compensation plan that vested in October 2015. Refer to Note 21 - Stock-Based Compensation for further information. (2) The revaluation of the Company's deferred tax assets and liabilities due to the lower corporate tax rate established by the Tax Act resulted in a $4.9 million tax benefit during the year ended September 30, 2018 . Companies may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. There was no unrecognized tax benefit for the years ended September 30, 2018 , 2017 and 2016 . The Company does not expect any significant changes to unrecognized tax benefits within the next twelve months. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense which is consistent with the recognition of these items in prior reporting periods. No interest and penalties were accrued as of September 30, 2018 , 2017 and 2016 . The Company files a federal consolidated return and files various state income tax returns and, generally, the Company is no longer subject to income tax examinations by the taxing authorities for years prior to September 30, 2015. The Company believes that it has appropriate support for the income tax positions taken and to be taken on the Company’s income tax returns. In addition, the Company believes its accruals for income tax liabilities are adequate for all open years based on an assessment of many factors including past experience and interpretations of the tax laws as applied to the facts of each matter.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company has three reportable business segments: the CSS segment, the SRS segment, and the CFS segment. Through the CSS segment, the Company provides home- and community-based human services to adults and children with intellectual and developmental disabilities. Through the SRS segment, the Company delivers services to individuals who have suffered acquired brain injury, spinal injuries and other catastrophic injuries and illnesses. The operations of the SRS segment were previously organized by management into two operating segments, NeuroRestorative and CareMeridian, based upon service type. The NeuroRestorative operating group provides behavioral therapies to individuals with brain injuries in post-acute community settings and the CareMeridian operating group provides a higher level of medical support to individuals with traumatic injuries . Effective as of October 1, 2017, NeuroRestorative and CareMeridian are operated under one management team and no longer represent individual components of the SRS segment. Through the CFS segment, the Company provides home- and community-based human services to youth with emotional, behavioral and/or medically complex challenges. Each operating group is aligned with the Company’s reporting structure and has a segment manager that is directly accountable for its operations and regularly reports results to the chief operating decision maker, which is the Company's Chief Operating Officer, for the purpose of evaluating these results and making decisions regarding resource allocations. The Company evaluates performance based on EBITDA. EBITDA for each segment is defined as income (loss) from continuing operations for the segment before income taxes, before depreciation and amortization, and interest income (expense). Activities classified as “Corporate and Other” in the table below relate to the results of the ADH operating segment and unallocated home office expenses and stock-based compensation expense. Total assets included in the Corporate and Other segment include assets associated with the ADH operating segment and assets maintained by the corporate entity including cash, restricted cash, and other current and non-current assets.

Earnings Per Share [Abstract]
Net Income Per Share	Net Income Per Share Basic net income per common share is computed by dividing net income by the basic weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the diluted weighted average number of common shares and common equivalent shares outstanding during the period. The weighted average number of common equivalent shares outstanding has been determined in accordance with the treasury-stock method. Common equivalent shares consist of common stock issuable on the exercise of outstanding options and vesting of restricted stock units when dilutive. The following table sets forth the computation of basic and diluted earnings per share (“EPS”): Year Ended September 30, 2018 2017 2016 Numerator Net income $ 14,886 $ 6,331 $ 9,187 Denominator Weighted average shares outstanding, basic 36,811,208 37,302,941 37,112,794 Weighted average common equivalent shares 134,200 163,384 150,121 Weighted average shares outstanding, diluted 36,945,408 37,466,325 37,262,915 Net income per share, basic and diluted $ 0.40 $ 0.17 $ 0.25 Equity instruments excluded from diluted net income per share calculation as the effect would have been anti-dilutive: Stock options 849,550 789,702 534,312 Performance and restricted stock units 282,744 92,435 83,793

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation Summary of Stock-Based Compensation Plans 2014 Plan Civitas maintains a 2014 Omnibus Incentive Plan (“2014 Plan”). As of September 30, 2018 , the 2014 Plan authorized the issuance of up to 7,786,478 shares of common stock as stock-based awards, including incentive stock options (“ISOs”), non-qualified stock options (“NSOs”), restricted stock units (“RSUs”) and performance based restricted stock units ("PRSUs"). Stock Options For the years ended September 30, 2018 , 2017 and 2016 , Civitas issued 155,041 , 319,604 and 230,739 NSOs, respectively, which vest over three years (one-third each year). The fair value of each option granted was estimated on the grant date using the Black-Scholes valuation model with the following assumptions: 2018 2017 2016 Risk-free interest rate 2.22% - 2.74% 1.83% - 2.08% 1.32% - 1.92% Expected term 6 years 6 years 6 years Expected volatility 33.56% - 35.81% 34.32% - 36.21% 34.65% - 36.20% Expected dividend yield — % — % — % Risk-free interest rate - The risk-free interest rate is equal to the U.S. federal Treasury bond rate consistent with the expected term assumption. Expected term - Expected term represents the period that Civitas’ option grants are expected to be outstanding. As Civitas had been operating as a private company, there is not sufficient historical data to calculate the expected term of the options. Therefore, management elected to utilize the “simplified method” to determine the expected term assumption. Under this approach, the weighted average expected life is presumed to be the average of the vesting term and the contractual term of the option. Expected volatility - Management has estimated volatility for the units granted based on the daily historical volatility of the Company's common stock and the daily historical volatility for a representative peer group over the expected term. The representative peer group is a group of companies selected based on industry and market capitalization, due to lack of sufficient historical publicly traded prices of the Company's common stock. Expected dividend yield - The expected dividend yield is zero as dividends are not expected to be paid in the foreseeable future. The fair value of the stock options on the date of grant is recognized as expense in the Company’s consolidated financial statements on a straight-line basis over the requisite service periods (vesting term) of the awards. Forfeitures are recognized as they occur. The actual expense recognized over the vesting period will only be for those awards that vest. The table below summarizes our stock option activity during fiscal year 2018 : Number of Shares Weighted- Average Exercise Price per Share Weighted- Average Remaining Life (Years) Aggregate Intrinsic Value Outstanding at September 30, 2017 877,781 $ 18.65 Granted 155,041 18.80 Forfeited 41,514 18.68 Exercised 17,608 17.00 Expired 34,487 19.54 Outstanding at September 30, 2018 939,213 $ 18.67 7.4 $ 2 Vested or expected to vest as of September 30, 2018 939,213 $ 18.67 7.4 $ 2 Exercisable at September 30, 2018 560,002 $ 18.54 6.6 $ — The total intrinsic values of options exercised was less than $0.1 million for each of the years ended September 30, 2018 , 2017 and 2016 . As of September 30, 2018 , there was $1.6 million of unrecognized compensation cost related to unvested stock options. This cost is expected to be recognized over a weighted-average period of 1.7 years. Restricted Stock Unit Awards (RSUs) For the years ended September 30, 2018 , 2017 and 2016 , Civitas granted 450,893 , 566,668 and 283,865 RSUs, respectively, to employees and members of the Board of Directors. The fair value of all RSUs is based on the closing market value of the Company's stock on the date of grant. The weighted average per share grant date fair value of the RSUs granted during the years ended September 30, 2018 , 2017 and 2016 was $17.87 , $17.79 , and $23.99 , respectively. These awards will vest over three years (one-third each year) for employee grants and one year ( 100% on the first anniversary of the grant date) for grants to members of the Board of Directors. The fair value of the restricted stock unit awards on the date of grant will be recognized as expense in the Company’s consolidated financial statements on a straight-line basis over the requisite service periods (vesting term) of the awards. Forfeitures are recognized as they occur. The actual expense recognized over the vesting period will only be for those awards that vest. A summary of our issued restricted stock unit awards is as follows: Number of Restricted Stock Units Weighted Average Grant-Date Fair Value Non-vested units at September 30, 2017 677,406 $ 19.20 Granted 450,893 17.87 Forfeited 86,140 18.77 Vested 206,260 19.88 Non-vested units at September 30, 2018 835,899 $ 18.35 The total fair values of RSUs that vested during the years ended September 30, 2018 , 2017 and 2016 , was $3.7 million , $4.5 million and $3.1 million , respectively. As of September 30, 2018 , there was $9.4 million of unrecognized compensation expense related to unvested restricted stock unit awards. This cost is expected to be recognized over a weighted-average period of 1.8 years . Performance Based Restricted Stock Units (PRSUs) During the year ended September 30, 2017, the Company awarded 45,624 PRSUs under the 2014 Plan. The PRSUs vest based upon the achievement of established performance targets in the third year of the three year performance period, or fiscal 2019. The number of PRSUs that may vest varies between 0% - 200% based on the achievement of such goals. The PRSUs were valued at $19.85 per share based on the closing price of the Company's common stock on the date of grant. During the year ended September 30, 2018, the Company awarded 50,834 PRSUs under the 2014 Plan. The PRSUs vest based upon the achievement of established performance targets in the third year of the three year performance period, or fiscal 2020. The number of PRSUs that may vest varies between 0% - 200% based on the achievement of such goals. The PRSUs were valued at a weighted average of $18.76 per share based on the closing price of the Company's common stock on the date of grant. To calculate compensation expense, the Company forecasts the likelihood of achieving the predefined performance targets and calculates the number of PRSUs expected to be earned. As of September 30, 2018 , the Company expects to recognize $0.7 million of stock-based compensation expense related to outstanding PRSUs based on the expected attainment levels. This cost is expected to be recognized over a weighted-average period of 2.0 years . A summary of PRSU activity for the year ended September 30, 2018 is as follows: Number of Performance Based Restricted Stock Units Weighted Average Grant-Date Fair Value Non-vested units at September 30, 2017 84,505 $ 19.85 Granted 50,834 18.76 Forfeited — — Vested — — Non-vested units at September 30, 2018 135,339 $ 19.44 Units expected to vest as of September 30, 2018 50,834 $ 18.76 For NSOs, RSUs and PRSUs under the 2014 Plan, the Company recorded $7.6 million , $8.4 million and $17.1 million of stock-based compensation expense during fiscal years 2018 , 2017 and 2016 , respectively. Stock-based compensation expense is included in general and administrative expense in the consolidated statements of income. Unit Plan Prior to October 1, 2015, NMH Investment maintained the Amended and Restated 2006 Unit Plan (the “Unit Plan”). Under the Unit Plan, NMH Investment issued units of limited liability company interests pursuant to such plan, consisting of Class B Common Units, Class C Common Units, Class D Common Units, Class E Common Units, Class F Common Units, Class G Common Units and Class H Common Units. These units derived their value from the value of the Company. On October 1, 2015, in connection with a secondary offering, NMH Investment distributed all of the 25,250,000 shares of our common stock it held to its existing members in accordance with their respective membership interests and pursuant to the terms of the NMH Investment's Limited Liability Company Agreement and the management unitholders agreements (the “Distribution”). The Distribution triggered the vesting condition for the Class H Common Units and the acceleration of unvested Class F Common Units. As a result, the Company recorded compensation expense of $10.5 million related to these awards during the quarter ended December 31, 2015. This expense is not deductible for tax purposes. The expense is included in general and administrative expense in the consolidated statements of income. As a result of the Distribution, the Unit Plan has concluded and there will be no future issuances under this plan.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions between the Company and its subsidiaries have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. On an on-going basis, we evaluate our estimates and judgments and methodologies.
New Accounting Pronouncements	Adoption of New Accounting Pronouncements Stock Compensation The Company adopted the guidance in Accounting Standards Update ("ASU") No. 2016-09 Compensation - Stock Compensation - Improvements to Employee Share-Based Payments Accounting (ASU No. 2016-09), on October 1, 2017. Under this standard, entities are permitted to make an accounting policy election to either estimate forfeitures on share-based payment awards, as previously required, or to recognize forfeitures as they occur. The Company has elected to recognize forfeitures as they occur and the impact of that change in accounting policy has been recorded as a $0.2 million cumulative effect adjustment to increase accumulated deficit as of October 1, 2017. ASU No. 2016-09 requires that all income tax effects related to settlements of share-based payment awards be reported in earnings as an increase (or decrease) to income tax expense (benefit). Previously, income tax benefits at settlement of an award were reported as an increase (or decrease) to additional paid-in capital to the extent that those benefits were greater than (or less than) the income tax benefits reported in earnings during the award’s vesting period. The requirement to report those income tax effects in earnings has been applied on a prospective basis to settlements occurring on or after October 1, 2017, and the impact of applying the guidance was not material to the consolidated financial statements for the year ended September 30, 2018. Application of the guidance may result in fluctuations in the Company’s effective tax rate depending on how many options are exercised, how many restricted stock units vest and the volatility of the Company’s stock price. ASU No. 2016-09 also requires that all income tax-related cash flows resulting from share-based payments be reported as operating activities in the statement of cash flows. Previously, income tax benefits at settlement of an award were reported as a reduction to operating cash flows and an increase to financing cash flows to the extent that those benefits exceeded the income tax benefits reported in earnings during the award’s vesting period. The change in classification of cash flows has no impact to prior periods, and the Company has elected to apply the changes in cash flow classification on a prospective basis. Income Taxes In March 2018, the FASB issued ASU No. 2018-05 Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 (ASU 2018-05). The update provides guidance associated with the accounting and disclosures around the enactment of the Tax Cuts and Jobs Act and the Securities and Exchange Commission’s Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”). This guidance was effective upon issuance and has been applied to the consolidated financial statements and related disclosures beginning in the second quarter of fiscal 2018, see Note 18 for the disclosures related to this amended guidance. Recent Accounting Pronouncements Revenue from Contracts with Customers— In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers Topic 606 (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The FASB has subsequently issued amendments to ASU No. 2014-09 that have the same effective date and transition date. ASU 2014-09, as amended, is effective for the Company's fiscal year beginning October 1, 2018, and the Company will adopt the new standard under the modified retrospective approach for contracts with customers. Under the modified retrospective approach, the guidance will be applied to the most current period presented, recognizing the cumulative effect of the adoption change as an adjustment to beginning retained earnings. In fiscal 2017, the Company established a formal program and cross-functional implementation team to identify design and implement changes to its accounting systems and policies and internal controls to support recognition and disclosure under the new standard. This process included a review of the requirements under the new standard compared to the current accounting policies for each of the Company’s revenue streams. As of the end of the fourth quarter, the Company completed its review and there is not expected to be a material impact on the consolidated financial statements upon implementation on October 1, 2018. The Company has implemented changes to accounting policies and controls to support the new revenue recognition and disclosure requirements. Leases— In February 2016, the FASB issued ASU No. 2016-02—Leases (Topic 842). The new standard requires that all lessees recognize the assets and liabilities that arise from leases on the balance sheet and disclose qualitative and quantitative information about its leasing arrangements. The standard will be effective for the Company on October 1, 2019. In July 2018, the FASB issued ASU No. 2018-11— Leases (Topic 842): Targeted Improvements (ASU 2018-11). Prior to ASU 2018-11, a modified retrospective transition was required for financing or operating leases existing at or entered into after the beginning of the earliest comparative period presented in the financial statements. ASU 2018-11 allows entities an additional transition method to the existing requirements whereby an entity could adopt the provisions of ASU 2016-02 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without adjustment to the financial statements for periods prior to adoption. The Company will elect this new transition method when it adopts ASU 2016-02 on October 1, 2019. The adoption of this standard is expected to have a material impact on the Company's financial position. As of September 30, 2018 and September 30, 2017 , the Company had gross operating lease commitments of approximately $374 million and $317 million , respectively. Upon adoption, a substantial portion of these lease commitments will be recorded at their net present value as a right of use asset and a lease obligation. Statement of Cash Flows — In November 2016, the FASB issued ASU No. 2016-18— Statement of Cash Flows (Topic 230): Restricted Cash . The update requires that a statement of cash flows present the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new standard is effective for the Company on October 1, 2018 and will be applied using a retrospective transition method by adjusting the prior periods presented to conform to the new presentation. As of September 30, 2018 and 2017, the Company had restricted cash amounts of $50.3 million . Business Combinations — In January 2017, the FASB issued ASU No. 2017-01— Business Combinations (Topic 805): Clarifying the Definition of a Business . The update provides guidance to determine when an integrated set of assets and activities is not a business. When substantially all of the fair value of the gross assets acquired, or disposed of, is concentrated in a single identifiable asset or a group of similar identifiable assets, then the acquisition, or disposition, is not a business. The amendments in this update should be applied prospectively on or after the effective date. No disclosures are required at transition. The new standard is effective for the Company on October 1, 2018. This standard could reduce the number of acquisitions that are treated as business combinations in the future. Fair Value Measurements — In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement , which is designed to improve the effectiveness of disclosures by removing, modifying and adding disclosures related to fair value measurements. The update is effective for the Company on October 1, 2020, with early adoption permitted. The Company is currently assessing the impact this update will have on its consolidated financial statements. Cloud Computing Arrangements — In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract . The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this update. The amendments in this update are effective for the Company on October 1, 2020, with early adoption permitted. The amendments in this update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is in the process of assessing the impact of the amendments in this update but does not expect it to have a material impact on the Company's consolidated financial statements.
Fair Value Measurements	Fair Value Measurements The accounting standard for fair value measurements defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and requires detailed disclosures about fair value measurements. Under this standard, fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The valuation techniques are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect certain market assumptions. This standard classifies these inputs into the following hierarchy: Level 1 Inputs - Quoted prices for identical instruments in active markets. Level 2 Inputs - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 Inputs - Instruments with primarily unobservable value drivers. The fair value hierarchy level is determined by asset class based on the lowest level of significant input. In periods of market inactivity, the observability of prices and inputs may be reduced for certain instruments. This condition could cause an instrument to be reclassified between levels. During the years ended September 30, 2018 and 2017 , there were no transfers between levels.
Cash Equivalents	Cash Equivalents The Company considers short-term investments with maturity dates of 90 days or less at the date of purchase to be cash equivalents.
Restricted Cash	Restricted Cash Restricted cash consists of a cash collateral account set up to support the issuance of letters of credit under the Company’s institutional letter of credit facility and funds provided from government payors restricted for use by individuals served by the Company.
Concentrations of Credit and Other Risks	Concentrations of Credit and Other Risks Financial instruments that potentially subject the Company to credit risk primarily consist of cash and cash equivalents, self-insurance receivables and accounts receivable. Cash and cash equivalents are deposited with federally insured commercial banks in the United States, which, at times may exceed federally insured limits of $250 thousand . The Company has not experienced any losses in such accounts. As of September 30, 2018 , our accounts exceeded federally insured limits by $58.1 million . The Company derives approximately 89% of its revenue from state and local government payors. These entities fund a significant portion of their payments to the Company through federal matching funds, which pass through various state and local government agencies.
Revenue Recognition	Revenue Recognition Revenue is reported net of allowances for unauthorized sales and estimated sales adjustments. Revenue is also reported net of any state provider taxes or gross receipts taxes levied on services the Company provides. Sales adjustments are estimated based on an analysis of historical sales adjustments and recent developments in payment trends. Revenue is recognized when evidence of an arrangement exists, the service has been provided, the price is fixed or determinable and collectability is reasonably assured. The Company recognizes revenue for services performed pursuant to contracts with various state and local government agencies and private health care agencies. The payment terms and rates of our contracts vary by jurisdiction and service type. The Company has four types of contractual arrangements with payors which include negotiated contracts, fixed fee contracts, retrospective reimbursement contracts and prospective payments contracts. Under the Company's units-of-service contracts, which include negotiated contracts and fixed fee contacts, revenue is recognized at the time the service is performed. Under the Company's cost reimbursement contracts, which include retrospective reimbursement contracts and prospective payment contracts, revenue is recognized at the time the service costs are incurred. For the Company’s cost-reimbursement contracts, the rate provided by the payor is based on a certain level of service and types of costs incurred in delivering the service. From time to time, the Company receives payments under cost-reimbursement contracts in excess of the allowable costs required to support those payments. In such instances, the Company estimates and records a liability for such excess payments. At the end of the contract period, any balance of excess payments is maintained as a liability until it is reimbursed to the payor or until the Company has exhausted efforts to make the reimbursement. Revenue in the future may be affected by changes in rate-setting structures, methodologies or interpretations that may be enacted in states where the Company operates or by the federal government.
Cost of Revenue	Cost of Revenue The Company classifies expenses directly related to providing services as cost of revenue, except for depreciation and amortization related to cost of revenue, which are shown separately in the consolidated statements of income. Direct costs and expenses principally include salaries and benefits for service provider employees, per diem payments to independently contracted host-home caregivers (“Mentors”), residential occupancy expenses, which are primarily composed of rent and utilities related to facilities providing direct care, certain expenses, such as food and medicine and transportation costs for individuals requiring services, professional and general liability expense, employment practices liability expense and workers’ compensation expense.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost and are depreciated using a straight-line method when placed into service, based on their estimated useful lives as follows: Asset Description Estimated Useful Life (in years) Land Indefinite Building 30 Building improvements 10 Leasehold improvements Not to exceed 7 years or length of lease Vehicles 5 Computer hardware and software 3 Furniture, fixtures and equipment 3-5 Capital lease assets are depreciated over the lesser of the lease term or the useful life of the asset. Expenditures for maintenance and repairs are charged to operating expenses as incurred. When assets are sold or retired, the corresponding cost and accumulated depreciation are removed from the related accounts and any gain or loss is recorded in the period of the sale or retirement.
Accounts Receivable	Accounts Receivable Accounts receivable primarily consist of amounts due from government agencies, not-for-profit providers and commercial insurance companies. An estimated allowance for doubtful accounts is recorded to the extent it is probable that a portion or all of a particular account will not be collected. In evaluating the collectability of accounts receivable, the Company considers a number of factors, including payment trends in individual states, age of the accounts and the status of ongoing disputes with third party payors. Complex rules and regulations regarding billing and timely filing requirements in various states are also a factor in our assessment of the collectability of accounts receivable. Actual collections of accounts receivable in subsequent periods may require changes in the estimated allowance for doubtful accounts. Changes in these estimates are charged or credited to revenue as a contractual allowance in the consolidated statements of income in the period of the change in estimate.
Goodwill and Indefinite-lived Intangible Assets	Goodwill and Indefinite-lived Intangible Assets The Company reviews costs of purchased businesses in excess of the fair value of net assets acquired (goodwill), and indefinite-lived intangible assets for impairment at least annually, unless significant changes in circumstances indicate a potential impairment may have occurred sooner. The Company conducts its annual impairment test for both goodwill and indefinite-lived intangible assets on July 1 st of each year. In fiscal 2016, the Company conducted the goodwill impairment test on a reporting unit basis using the two step process in accordance with the guidance in ASC 350. The Company had the option to first assess qualitative factors to determine whether further impairment testing is necessary. The Company elected to bypass the qualitative assessments and proceeded directly to the two-step impairment test. The first step is to compare the fair value of the reporting unit with its carrying value. The fair value of the reporting unit is determined by using the income approach, specifically the discounted cash flow method. If the carrying amount of the reporting unit exceeds its fair value then the second step of the goodwill impairment test is performed. The second step of the goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill in order to determine the amount of impairment to be recognized. The excess of the carrying value of goodwill above the implied goodwill, if any, would be recognized as an impairment charge. Fair values are estimated using the discounted cash flow method. Beginning in fiscal 2017, the Company no longer performs Step 2 of the goodwill impairment test. The annual impairment tests in fiscal 2017 and fiscal 2018 were performed by comparing the fair value of a reporting unit with its carrying value. The fair value of the reporting unit is determined by using the income approach, specifically the discounted cash flow method, and corroborated by the market approach. If the fair value of the reporting unit exceeds its carrying amount, goodwill is not impaired and no further testing is required. If the fair value of the reporting unit is less than the carrying value, an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. For its indefinite-lived intangible assets, the Company has elected to bypass the qualitative assessments and proceed directly to the quantitative impairment test. The impairment test for indefinite-lived intangible assets requires the determination of the fair value of the intangible asset. If the fair value of the indefinite-lived intangible asset is less than its carrying value, an impairment loss is recognized in an amount equal to the difference. Fair values are estimated using the relief from royalty method. As described above, the fair value of a reporting unit and intangible asset is based on discounted estimated future cash flows. The assumptions used to estimate fair value include management’s best estimates of future operating cash flows, including revenue growth, tax rates, capital expenditures, discount rates and working capital changes. As such, actual results may differ from these estimates and lead to a revaluation of the Company’s goodwill and indefinite-lived intangible assets.
Impairment of Long-Lived Tangible and Intangible Assets	Impairment of Long-Lived Tangible and Intangible Assets The Company reviews long-lived tangible and intangible assets for impairment when events or circumstances have occurred that indicate the estimated useful life of these assets may warrant revision or that the carrying amount of these assets may be impaired. To compute whether assets have been impaired, the estimated undiscounted future cash flows for the estimated remaining useful life of the assets are compared to the carrying value. To the extent that the future cash flows are less than the carrying value, the assets are written down to the estimated fair value of the asset.
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are determined by multiplying the differences between the financial reporting and tax reporting bases for assets and liabilities by the enacted tax rates expected to be in effect when such differences are recovered or settled. Valuation allowances on deferred tax assets are estimated based on the Company’s assessment of the realizability of such amounts. The Company recognizes the benefits of tax positions when certain criteria are satisfied. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense.
Derivative Financial Instruments	Derivative Financial Instruments The Company reports derivative financial instruments on the balance sheet at fair value and establishes criteria for designation and effectiveness of hedging relationships. Changes in the fair value of derivatives are recorded each period in current operations or in the consolidated statements of comprehensive income (loss) depending upon whether the derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. The Company, from time to time, enters into interest rate swap agreements to hedge against variability in cash flows resulting from fluctuations in the benchmark interest rate, which is LIBOR, on the Company’s debt. These agreements involve the exchange of variable interest rates for fixed interest rates over the life of the swap agreement without an exchange of the notional amount upon which the payments are based. On a quarterly basis, the differential to be received or paid as interest rates change is accrued and recognized as an adjustment to interest expense in the accompanying consolidated statements of income. In addition, on a quarterly basis, the mark to market valuation is recorded as an adjustment to gain (loss) on derivative within the consolidated statements of comprehensive income with any ineffective portion recorded to Interest expense within the consolidated statement of income. The related amount receivable from or payable to counterparties is included as an asset or liability, respectively, in the Company’s consolidated balance sheets.
Stock-Based Compensation	Stock-Based Compensation Prior to the Company's initial public offering ("IPO"), NMH Investment maintained an equity-based compensation plan, and from time to time it issued units of limited liability company interests pursuant to such plan. The units were available for issuance to the Company’s employees and members of the Board of Directors. The Company recognized the fair value of these awards as compensation expense over the requisite services period or when the satisfaction of the vesting conditions were determined to be probable. In October 2015, NMH Investment distributed all of the 25,250,000 shares of our common stock it held to its existing members in accordance with their respective membership interests and pursuant to the terms of the NMH Investment's Limited Liability Company Agreement and the management unitholders agreements (the “Distribution”). The Distribution triggered the vesting conditions for all unvested awards. As a result, the Company recorded compensation expense of $10.5 million that is included in General and administrative expense on the consolidated statement of income during the year ended September 30, 2016. In fiscal 2014, Civitas adopted an equity-based compensation plan and began issuing stock-based awards including non-qualified stock options ("NSOs"), restricted stock units ("RSUs"), and performance based restricted stock units ("PRSUs"). The Company recognizes the fair value of stock-based compensation expense over the requisite service period of the individual grantee, which equals the vesting period. The fair value of each NSO granted was estimated on the grant date using the Black-Scholes valuation model. The fair value of each RSU was determined based on the Company's closing stock price on the date of grant. The fair value of each PRSU was determined based on either the Company's closing stock price on the date of grant or through a Monte Carlo simulation methodology for those awards that included a market condition. The number of performance based restricted stock units earned is determined based on the Company's attainment of predefined performance targets set by the Compensation Committee. At each reporting period, the Company assesses the number of performance based restricted stock units expected to vest based on the expected attainment of the performance targets. The Company recognizes forfeitures as they occur. The actual expense recognized over the vesting period will only be for those awards that vest.
Self-Insurance	Self-Insurance The Company maintains insurance for professional and general liability, workers’ compensation, automobile liability and health insurance with policies that include self-insured retentions. Employment practices liability is fully self-insured. The Company records expenses related to claims on an incurred basis, which includes estimates of fully developed losses for both reported and unreported claims. The accruals for the health, workers’ compensation, automobile, employment practices liability and professional and general liability programs are based on analyses performed internally by management and for certain balances, take into account reports by independent third party actuaries. Self-insurance accruals are periodically re-evaluated and increased or decreased based on new information. The Company reports its insurance liabilities on a gross basis without giving effect to insurance recoveries. Insurance recovery receivables are presented in Prepaid expenses and other current assets and Other assets on the consolidated balance sheets. Self-insured liabilities are presented in Accrued payroll and related costs, Other accrued liabilities and Other long-term liabilities on the Company’s consolidated balance sheets.
Self-Insurance Gross versus Net Presentation	The Company reports its insurance liabilities on a gross basis without giving effect to insurance recoveries. Insurance recovery receivables are presented in Prepaid expenses and other current assets and Other assets on the consolidated balance sheets. Self-insured liabilities are presented in Accrued payroll and related costs, Other accrued liabilities and Other long-term liabilities on the Company’s consolidated balance sheets.
Legal Contingencies	Legal Contingencies The Company reserves for costs related to contingencies when a loss is probable and the amount is reasonably estimable or a range of loss can be determined. These accruals represent management’s best estimate of probable loss. Disclosure is also provided when it is reasonably possible that a loss will be incurred or when it is reasonably possible that the amount of loss will exceed the recorded provision. Significant judgment is required in both the determination of probability and the determination as to whether an exposure is reasonably estimable. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, the Company reassesses the potential liability related to pending claims and litigation and may revise its estimates. These revisions in the estimates of the potential liabilities could have a material impact on our consolidated results of operations and financial position.
Leases	Leases The Company accounts for leases in accordance with ASC Topic 840 Leases . For lease agreements that provide for escalating rent payments and rent holidays, the Company recognizes rent expense on a straight-line basis over the non-cancellable lease term and option renewal periods where failure to exercise such options would result in an economic penalty such that the renewal appears, at the inception of the lease, to be reasonably assured. The lease term commences when the Company becomes obligated under the terms of the lease agreement.
Subsequent Events	Subsequent Events The Company considers events or transactions that have occurred after the balance sheet date of September 30, 2018 , but prior to the filing of the financial statements with the Securities and Exchange Commission, or SEC, to provide additional evidence relative to certain estimates or to identify matters that require additional recognition or disclosure. Subsequent events have been evaluated through the filing of the financial statements accompanying this Annual Report on Form 10-K.
