Organization Consolidation And Presentation Of Financial Statements [Abstract]
Description of Business	1. Description of Business AAC Holdings, Inc. (collectively with its subsidiaries, the “Company” or “Holdings”), was incorporated on February 12, 2014 for the purpose of acquiring all the common stock of American Addiction Centers, Inc. (“AAC”) and to engage in certain reorganization transactions as more fully described in Note 3. The Company is headquartered in Brentwood, Tennessee and provides inpatient and outpatient substance abuse treatment services for individuals with drug and alcohol addiction. In addition to the Company’s inpatient and outpatient substance abuse treatment services, the Company performs drug testing and diagnostic laboratory services and provides physician services to clients. At December 31, 2016, the Company, through its subsidiaries, operated 12 residential substance abuse treatment facilities located throughout the United States, and 18 standalone outpatient centers, and 202 sober living beds across three locations. The Company is in the process of expanding Oxford Treatment Center, where it opened an additional 24 residential beds in September 2016 and currently anticipates completing an additional 24 residential beds and 48 sober living beds in the second quarter of 2017. In addition, the Company has leased one floor from New Orleans East Hospital in New Orleans, Louisiana, where it intends to operate 36 in-network beds to provide detoxification and residential treatment services. The beds are expected to be operational in the second quarter of 2017, subject to receiving licensure, and will be operated by Townsend’s clinical staff. The Company is also an internet marketer in the addiction treatment industry operating a broad portfolio of internet assets that service millions of website visits each month. Through the acquisition (the “RSG Acquisition”) of Referral Solutions Group, LLC (“RSG”) in July 2015, and its wholly owned subsidiary Recovery Brands, LLC (“Recovery Brands”), a leading publisher of addiction related websites such as Rehabs.com and Recovery.org, the Company serves families and individuals struggling with addiction and seeking treatment options through comprehensive online directories of treatment providers, treatment provider reviews, forums and professional communities. Recovery Brands also provides online marketing solutions to other treatment providers such as enhanced facility profiles, audience targeting, lead generation and tools for digital reputation management.

Accounting Policies [Abstract]
Basis of Presentation	2. Basis of Presentation Principles of Consolidation The Company conducts its business through limited liability companies and C-corporations, each of which is a direct or indirect wholly owned subsidiary of the Company. The accompanying consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, and the accounts of variable interest entities (“VIEs”) in which the Company is the primary beneficiary, which include certain professional groups through rights granted to the Company by contract to manage and control the business of such professional groups. All intercompany transactions and balances have been eliminated in consolidation. The Private Share Exchange (defined below) between the Company and AAC’s stockholders (as discussed in Note 3) was accounted for similar to a common control transaction resulting in the assets, liabilities, and equity of AAC being carried over at their historical bases. At the time of the Private Share Exchange, Holdings was a shell company that had not conducted any business and had no material assets or liabilities. As such, the historical financial statements presented for periods prior to the Private Share Exchange represent the historical results of operations of AAC. During the year ended December 31, 2014, the Company consolidated one real estate VIE, Behavioral Healthcare Realty, LLC (“BHR”) through April 15, 2014, at which point BHR was acquired by the Company and became a wholly owned subsidiary of the Company (see Note 3 for further discussion). At the time of the BHR Acquisition, BHR leased two treatment facilities to the Company under long-term triple net leases and was renovating and constructing additional treatment facilities that it planned to lease to the Company. The Company was the primary beneficiary as a result of its guarantee of BHR’s debt prior to the BHR Acquisition. The Company also consolidated six professional groups (“Professional Groups”) that constituted VIEs as of December 31, 2015 and seven Professional Groups that constituted VIEs as of December 31, 2016. The Professional Groups are responsible for the supervision and delivery of medical services to the Company’s clients. The Company provides management services to the Professional Groups. Based on the Company’s ability to direct the activities that most significantly impact the economic performance of the Professional Groups, provide necessary funding to the Professional Groups and the obligation and likelihood of absorbing all expected gains and losses of the Professional Groups, the Company has determined that it is the primary beneficiary of these Professional Groups. The accompanying consolidated balance sheets include assets of $1.4 million as of both December 31, 2016 and 2015, respectively, and liabilities of $0.7 million and $0.6 million, respectively, related to the VIEs. The accompanying consolidated income statements include net loss attributable to noncontrolling interest of $5.2 million, $2.8 million and $1.2 million related to the VIEs for the years ended December 31, 2016, 2015 and 2014, respectively. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Business Combinations [Abstract]
Reorganization Transactions	3. Reorganization Transactions On April 15, 2014, the Company completed the following transactions which were all completed substantially concurrently (collectively, the “Reorganization Transactions”): • A voluntary private share exchange with certain stockholders of AAC, whereby holders representing over 93.6% of the outstanding shares of common stock of AAC exchanged their shares on a one-for-one basis for shares of the Company’s common stock (the “Private Share Exchange”); • The acquisition of all of the outstanding common membership interests of BHR, an entity controlled by related parties, which through its subsidiaries owns properties located in Florida, Nevada and Texas, in exchange for $3.0 million in cash, the assumption of a $1.8 million term loan and 820,124 shares of the Company’s common stock (the “BHR Acquisition”); and • The acquisition of all of the outstanding membership interests of Clinical Revenue Management Services, LLC (“CRMS”), an entity controlled by related parties, which provides client billing and collection services for the Company, in exchange for $0.5 million in cash and 234,324 shares of the Company’s common stock. As a result of the foregoing transactions, the Company owned (i) over 93.6% of the outstanding common stock of AAC, (ii) 100% of the outstanding common membership interests in BHR, and (iii) 100% of the outstanding membership interests in CRMS. To help fund or facilitate these transactions, the following additional financing transactions were undertaken in 2014 prior to or in connection with the aforementioned transactions: (i) AAC sold 741,322 shares of its common stock in a private placement to certain accredited investors from February 2014 through April 2014, with net proceeds of $6.0 million, (ii) BHR sold 8.5 Series A Preferred Units in a private placement to certain accredited investors in January and February 2014 with net proceeds of $0.4 million (See Note 10), (iii) BHR redeemed 36.5 Series A Preferred Units from certain accredited investors in April 2014 (See Note 10) and (iv) BHR sold 160 new Series A Preferred Units in a private placement to an accredited investor in April 2014 with net proceeds of $7.8 million (see Note 10). Initial Public Offering and Short-Form Merger On October 7, 2014, the Company completed an initial public offering (“IPO”) of 5,750,000 shares of its common stock at a public offering price of $15.00 per share, which included the exercise in full of the underwriters’ option to purchase an additional 250,000 shares from the Company and 500,000 shares from certain stockholders. Net proceeds to the Company from the IPO were approximately $68.8 million, after deducting underwriting discounts and offering costs. On November 10, 2014, the Company completed a subsidiary short-form merger with AAC and a wholly-owned merger subsidiary whereby the legacy holders of AAC common stock who did not participate in the Private Share Exchange received 1.571119 shares of Holdings common stock for each share of AAC common stock owned at the effective time of the merger (for an aggregate of approximately 293,040 shares of Holdings common stock). Upon completion of the short-form merger, Holdings owned 100% of the outstanding shares AAC. The Private Share Exchange was accounted for similar to a common control transaction resulting in the assets, liabilities and equity of AAC being carried over at their historical bases. Shares of AAC common stock that were not exchanged remained in mezzanine equity or stockholders’ equity until the completion of the short-form merger in November 2014. The short-form merger was accounted for as an equity transaction in accordance with ASC 810, Consolidation

Summary of Significant Accounting Policies	4. Summary of Significant Accounting Policies Use of Estimates The preparation of consolidated 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, liabilities, revenues and expenses at the date and for the periods that the consolidated financial statements are prepared. On an ongoing basis, the Company evaluates its estimates, including those related to insurance adjustments, provisions for doubtful accounts, goodwill and intangible assets, long-lived assets, deferred revenues and income taxes. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could materially differ from those estimates. General and Administrative Costs The majority of the Company’s expenses are “cost of revenue” items. Costs that could be classified as general and administrative expenses include the Company’s corporate overhead costs, which were $74.8 million, $48.2 million, and $25.3 million for the years ended December 31, 2016, 2015, and 2014, respectively. Client Related Revenues The Company provides services to its clients in both inpatient and outpatient treatment settings. Client related revenues are recognized when services are performed at estimated net realizable value from clients, third-party payors and others for services provided. The Company receives the majority of payments from commercial payors at out-of-network rates. Client related revenues are recorded at established billing rates less adjustments to estimate net realizable value. Adjustments are recorded to state client service revenues at the amount expected to be collected for the service provided based on historic adjustments for out-of-network services not under contract. Prior to admission, each client’s insurance is verified and the client self-pay amount is determined. The client self-pay portion is generally collected upon admission. In some instances, clients will pay out-of-pocket as services are provided or will make a deposit and negotiate the remaining payments as part of the services. These out-of-pocket payments are included in accrued liabilities in the accompanying consolidated balance sheets and revenues related to these payments are deferred and recognized over the period services are provided. From time to time, scholarships may be provided to a limited number of clients. The Company does not recognize revenues for care provided via scholarships. For the year ended December 31, 2016, approximately 10.5% of the Company’s revenue reimbursements came from Blue Cross Blue Shield of Florida, 10.4% came from Blue Cross Blue Shield of Texas, and 10.4% came from Aetna. No other payor accounted for more than 10% of the Company’s revenue reimbursements for the year ended December 31, 2016. For the year ended December 31, 2015, approximately 15.1% of the Company’s revenues were reimbursed by Anthem Blue Cross Blue Shield of Colorado; 12.5% by Blue Cross Blue Shield of Texas; 11.5% by Aetna, and 11.1% were reimbursed by Blue Cross Blue Shield of California. No other payor accounted for more than 10% of revenue reimbursements for the year ended December 31, 2015. For the year ended December 31, 2014, approximately 18.1% of the Company’s revenue reimbursements came from Anthem Blue Cross Blue Shield of Colorado, 13.3% came from Blue Cross Blue Shield of Texas, 12.9% came from Aetna, 10.5% Other Revenue The Company’s other revenue consists of service charges from the delivery of quality targeted leads to behavioral and mental health service businesses through the Company’s operating subsidiary Referral Solutions Group, LLC, which was acquired on July 2, 2015, and diagnostic laboratory services provided to clients of third-party addiction treatment providers Allowance for Contractual and Other Discounts The Company derives the majority of its revenues from commercial payors at out-of-network rates. Management estimates the allowance for contractual and other discounts based on its historical collection experience. The services authorized and provided and related reimbursement are often subject to interpretation and negotiation that could result in payments that differ from the Company’s estimates. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable primarily consists of amounts due from third-party payors (non-governmental) and is recorded net of contractual discounts. The Company’s ability to collect outstanding receivables is critical to its results of operations and cash flows. Accounts receivable is reported net of an allowance for doubtful accounts, which is management’s best estimate of accounts receivable that could become uncollectible in the future. Accordingly, accounts receivable reported in the Company’s consolidated financial statements is recorded at the net amount expected to be received. The Company’s primary collection risks are (i) the risk of overestimating net revenues at the time of billing that may result in the Company receiving less than the recorded receivable, (ii) the risk of non-payment as a result of commercial insurance companies denying claims, (iii) the risk that clients will fail to remit insurance payments to the Company when the commercial insurance company pays out-of-network claims directly to the client and (iv) resource and capacity constraints that may prevent the Company from handling the volume of billing and collection issues in a timely manner, (v) the risk that clients do not pay the Company for their self-pay balance (including co-pays, deductibles and any portion of the claim not covered by insurance) and (vi) the risk of non-payment from uninsured clients. The Company’s allowance for doubtful accounts is based on historical experience, but management also takes into consideration the age of accounts, creditworthiness and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. Approximately $10.4 million of the accounts receivable, net the of the allowance for doubtful accounts, at December 31, 2016 includes accounts where the Company has received a partial payment from a commercial insurance company and the Company is continuing to pursue additional collections for the balance that the Company estimates remains outstanding. At December 31, 2016, 11.6% of accounts receivable was from Anthem Blue Cross Blue Shield of Colorado and 10.3% was from Anthem Blue Cross Blue Shield of California. At December 31, 2015, 22.4% of accounts receivable was from Anthem Blue Cross Blue Shield of Colorado and 15.0% was from Blue Cross Blue Shield of California. No other payor accounted for more than 10% of accounts receivable at December 31, 2016 or 2015. A summary of activity in the Company’s allowance for doubtful accounts is as follows (in thousands): Balance at December 31, 2013 $ 13,320 Additions charged to provision for doubtful accounts 11,391 Accounts written off, net of recoveries (16,243 ) Balance at December 31, 2014 $ 8,468 Additions charged to provision for doubtful accounts 18,113 Accounts written off, net of recoveries (9,704 ) Balance at December 31, 2015 $ 16,877 Additions charged to provision for doubtful accounts 21,485 Accounts written off, net of recoveries (10,234 ) Balance at December 31, 2016 $ 28,128 Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. Property and Equipment Property and equipment are stated at cost or at acquisition date fair value for assets obtained in business combinations, net of accumulated depreciation and amortization. Expenditures for maintenance and repairs are charged to expense as incurred. The Company capitalizes interest on construction projects and such interest is included in the cost of the related asset. Assets held for development are classified as construction in progress and the Company does not depreciate these assets until they are placed in service. Leasehold improvements are amortized over their estimated useful lives or the remaining lease period, whichever is less. Assets under capital leases are amortized over the lease term or in the event of transfer of ownership at the end of the lease over the economic life of the leased asset. Amortization expense related to assets under capital lease is included with depreciation and amortization expense in the consolidated statements of operations. Depreciation is calculated using the straight-line method over the estimated economic useful lives of the assets, as follows: Range of Lives Computer software and equipment 3 years Buildings 36 years Furniture, fixtures and equipment 5 years Vehicles 5 years Equipment under capital lease 3-5 years Leasehold improvements Life of the asset or lease, whichever is less Goodwill and Intangible Assets The Company has only one operating segment, substance abuse/behavioral healthcare treatment services, for segment reporting purposes. The substance abuse/behavioral healthcare treatment services operating segment represents one reporting unit for purposes of the Company’s goodwill impairment test. Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired. Goodwill and intangible assets with indefinite lives are not amortized, but instead are tested for impairment at least annually or whenever events or changes in circumstances indicate the carrying value may not be recoverable. If the carrying value of goodwill exceeds its implied fair value, an impairment loss is recorded. The Company’s annual impairment tests of goodwill and other indefinite-lived intangibles in 2016 and 2015 resulted in no impairment charges. The Company’s other intangible assets principally relate to trademarks, marketing intangibles, non-compete agreements, and leasehold interests acquired during business combinations. Trademarks and marketing intangibles are amortized over a period of ten years, non-compete agreements are amortized over the term of the agreements, and leasehold interests are amortized over the remaining life of the leases. Long-Lived Asset Impairment Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net undiscounted cash flows expected to be generated by the asset. Impairment is measured by the amount by which the carrying value of the assets exceeds the fair value of the assets. The Company did not identify any indicators of impairment during the years ended December 31, 2016 and 2015. Accrued Liabilities The Company’s accrued liabilities, reflected as a current liability in the accompanying consolidated balance sheets, consist of the following (in thousands): Year Ended December 31, 2016 2015 Accrued payroll liabilities 13,501 $ 10,090 Accrued litigation settlement 962 800 Accrued legal fees 915 479 Income taxes payable 244 2,527 Accrued property, plant, and equipment 2,650 1,487 Other 8,470 6,270 Total accrued liabilities $ 26,742 $ 21,653 Segments The focus of all Company operations is centered on a single service, substance abuse/behavioral healthcare treatment. As such, the Company has one operating segment. The Company is organized and operates as one reportable segment, consisting of various treatment facilities located in the United States. The treatment facilities operate in the same industry and have similar economic characteristics, services and clients. Management has the ability to direct and serve clients in any of these facilities, which allows management to operate the Company’s business and analyze its revenues on a system-wide basis rather than focusing on any individual facility. The Company’s chief operating decision maker evaluates performance and manages resources based on the results of the consolidated operations as a whole. Advertising Expenses Advertising costs are expensed as the related activity occurs. Stock-Based Compensation The Company accounts for stock-based compensation to employees using a fair-value based method for costs related to all share-based payments. Prior to the Company’s stock being traded in an active market, the Company estimated the fair value of employee restricted stock awards on the date of grant based on the appraised fair value. The fair value of the portion of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the requisite service periods in the Company’s consolidated statements of operations. Earnings Per Share Basic and diluted earnings per common share are calculated based on the weighted-average number of common shares outstanding in each period and dilutive stock options, non-vested shares, convertible debt securities, and warrants, to the extent such securities have a dilutive effect on earnings per share using the treasury stock method. Income Taxes The Company accounts for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on the deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for significant deferred tax assets when it is more likely than not that such assets will not be recovered. The Company’s practice is to recognize interest and/or penalties related to uncertain income tax positions in income tax expense. For the years ended December 31, 2016, 2015 and 2014, the Company had no accrued interest or penalties related to income tax matters. VIEs included in the accompanying consolidated financial statements consist of various corporations and a partnership. As discussed in Note 3, the Company acquired BHR on April 15, 2014, prior to that date, BHR was a partnership for income tax purposes. Partnerships are characterized as flow through entities for federal and certain state income tax purposes, taxes for the VIEs that are considered partnerships are not recorded in the accompanying consolidated financial statements, except for certain state taxes imposed at the entity level. Taxes that are imposed on the owners of these partnerships are not included in the accompanying consolidated financial statements. Taxes attributable to BHR after the acquisition date are included in these consolidated financial statements. Fair Value Measurements Fair value, for financial reporting purposes, is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Disclosure is required about how fair value was determined for assets and liabilities and following a hierarchy for which these assets and liabilities must be grouped, based on significant levels of inputs as follows: Level 1—quoted prices in active markets for identical assets or liabilities; Level 2—quoted prices in active markets for similar assets and liabilities and inputs that are observable for the asset or liability; or Level 3—unobservable inputs for the asset or liability, such as discounted cash flow models or valuations. The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Comprehensive Income As of December 31, 2016, 2015, and 2014, the Company did not have any components of other comprehensive income. As such, comprehensive income equaled net income for each of the periods presented in the accompanying consolidated statements of operations. Recent Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). The new guidance eliminates the requirement to calculate the implied fair value of goodwill (i.e., Step 2 of the current goodwill impairment test) to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on the current Step 1). ASU 2017-04 is effective for annual and any interim impairment tests for periods beginning after December 15, 2019. The Company is currently evaluating the provisions of ASU 2017-04 to determine the impact on the Company’s financial statements. In August 2016, the FASB issued (“ASU”) No. 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). Among other clarifications, ASU 2016-15 clarifies certain items, including the classification of payments for debt prepayment or debt extinguishment costs, including third-party costs, premiums paid, and other fees paid to lenders that are directly related to the debt prepayment or debt extinguishment, excluding accrued interest, which will now be included in the Financing Activities section in the Statements of Cash Flows. The new standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-15 is not expected to have a material impact on the Company’s results of operations. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses: Measurement of Credit Losses In March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 requires that all excess tax benefits and tax deficiencies resulting from share-based payments be recognized as income tax expense or benefit in the income statement, which eliminates the accounting for additional paid-in capital pools. ASU 2016-09 also allows companies to make an entity-wide policy election to either estimate the number of stock-based awards that are expected to vest or account for forfeitures as they occur. With regards to the Statement of Cash Flows, both inflows and outflows of cash related to excess tax benefits will be classified as operating activities, whereas prior to this update, excess tax benefits as cash inflows were to be classified as financing activities. Also, cash paid by an employer when directly withholding shares for tax-withholding purposes (“net share settlement”) will now be classified as a financing activity. The new standard is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is in the early stages of evaluating the impact that adoption of this new standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases”. The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company anticipates that the adoption of ASU 2016-2 will result in an increase in both total assets and total liabilities. In November 2015, the FASB issued ASU 2015-17, “Income Taxes: Balance Sheet Classification of Deferred Taxes” (“ASU 2015-17”). ASU 2015-17 requires deferred tax assets and liabilities to be netted and presented as a single non-current amount in the balance sheet, rather than separating them into current and non-current amounts. The Company prospectively adopted the provisions of ASU 2015-17 during the fourth quarter of 2015. Prior periods were not retrospectively adjusted. The adoption of ASU 2015-17 had no impact on the Company’s results of operations or cash flows. In September 2015, the FASB issued ASU 2015-16, “Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments” (“ASU 2015-16”). ASU 2015-16 eliminates the requirement for an acquirer to retrospectively adjust its financial statements for changes to provisional amounts that are identified during the measurement-period following the consummation of a business combination. Instead, ASU 2015-16 requires these types of adjustments to be made during the reporting period in which they are identified and would require additional disclosure or separate presentation of the portion of the adjustment that would have been recorded in the previously reported periods as if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective prospectively for fiscal years beginning after December 15, 2015, including interim periods within those years, . The adoption of ASU 2015-16 did not have a material impact on the Company’s results of operations. In April 2015, the FASB issued ASU No. 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software.” The update was effective for financial statements issued for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years, with early adoption permitted. ASU 2015-05 provides guidance for customer’s accounting for fees paid in a cloud computing arrangement. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. An entity can elect to adopt the amendments either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. The adoption of ASU 2015-05 on January 1, 2016 did not have a material impact on the Company’s consolidated financial statements. In March 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs”. The update is effective for financial statements issued for fiscal years beginning after December 15, 2015, and those interim periods within those fiscal years, with early adoption permitted. The update requires debt issuance costs related to a note to be reported in the balance sheet as a direct deduction from the face amount of that note on a retrospective basis upon adoption. The Company elected to early adopt the revised guidance and presented $1.9 million of deferred debt issuance costs associated with the Company’s 2015 Credit Facility (as later defined) net of the debt balance at December 31, 2015 (see Note 9). In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers”, which outlines a single comprehensive model for recognizing revenue and supersedes most existing revenue recognition guidance, including guidance specific to the healthcare industry. Updates to this standard have been issued subsequent to the initial ASU 2014-09. Companies across all industries will use a new five-step model to recognize revenue from customer contracts. The new standard, which replaces nearly all existing GAAP revenue recognition guidance, will require significant management judgment in addition to changing the way many companies recognize revenue in their financial statements. The standard is effective for public entities for annual and interim periods beginning after December 15, 2017, with early adoption permitted for annual periods beginning after December 15, 2016. As the Company progresses with its implementation efforts to adopt ASU 2014-09, management continues to evaluate and refine its estimates of the anticipated impact the new standard will have on its revenue recognition policies, procedures, financial position, results of operations, cash flows and financial disclosures. Specifically, the Company is continuing to evaluate the impact the adoption will have on the presentation of the provision for doubtful accounts in the consolidated statements of operations and whether some or all of the provision for doubtful accounts will continue to be presented as a separate line item or will be recorded as a direct reduction to revenues.

Earnings Per Share [Abstract]
Earnings Per Share	5. Earnings Per Share Basic EPS is computed by dividing net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Common shares outstanding include both the common shares classified as mezzanine equity and those classified as equity. For the calculation of diluted EPS, net income attributable to common stockholders for basic EPS is adjusted by the effect of dilutive securities, including awards under stock-based payment arrangements, and outstanding convertible debt securities. Diluted EPS attributable to common stockholders is computed by dividing net income attributable to common stockholders by the weighted-average number of fully diluted common shares outstanding during the period. The following tables reconcile the numerator and denominator used in the calculation of basic and diluted EPS for years ended December 31, 2016, 2015 and 2014 (in thousands except share and per share amounts): Year Ended December 31, 2016 2015 2014 Numerator Net (loss) income attributable to AAC Holdings, Inc. $ (589 ) $ 11,174 $ 7,548 Less: Series A Preferred Unit dividends — (147 ) (693 ) Less: Redemption of BHR Series A Preferred Units — (534 ) — Net (loss) income available to common shares $ (589 ) $ 10,493 $ 6,855 Denominator Weighted-average shares outstanding – basic 22,718,117 21,605,037 16,557,655 Dilutive securities — 56,222 61,525 Weighted-average shares outstanding – diluted 22,718,117 21,661,259 16,619,180 Basic earnings per share $ (0.03 ) $ 0.49 $ 0.41 Diluted earnings per share $ (0.03 ) $ 0.48 $ 0.41 The Company has included common stock that is classified as mezzanine equity in the denominator for basic and diluted EPS calculations. The Company had 25,181 dilutive shares for the year ended December 31, 2016 that are not included in the earnings per share calculation above, because to do so would be anti-dilutive for the period presented.

Acquisitions

Business Combinations [Abstract]
Acquisitions	6 . 2016 Acquisitions On April 1, 2016, the Company acquired certain assets of Wetsman Forensic Medicine, L.L.C. (d/b/a Townsend) and its affiliates (“Townsend”), a substance abuse treatment provider in Louisiana that operated seven in-network outpatient centers delivering intensive outpatient treatment as well as a 32-bed in-network facility located in Scott, Louisiana, of which 20 beds are licensed for detoxification and inpatient treatment, and an in-network lab that services these facilities (the “Townsend Acquisition”), for total consideration of $13.5 million in cash and 447,369 in restricted shares of AAC Holdings’ common stock. The purchase agreement includes provisions for contingent consideration of up to $2.0 million, consisting of cash and shares of AAC Holdings’ common stock currently held in escrow, if certain financial targets for the year ending December 31, 2016 are met. The Company determined the fair value of the contingent consideration at the acquisition date to be $1.4 million, which was included in the purchase price and allocated to the net assets acquired and liabilities assumed accordingly. The $0.6 million difference between the contingent consideration and fair value was recorded as a contingent consideration asset on the acquisition date. The purchase price was based upon arms-length negotiations between the Company and Townsend, an unrelated third party, that resulted in a premium to the fair value of the net assets acquired and, correspondingly, the recognition of goodwill. The amount recorded for goodwill is consistent with the Company’s intentions for the acquisition and is deductible for income tax purposes. As of December 31, 2016, the Company measured the contingent consideration requirements in accordance with the purchase agreement noting that the required financial targets for the year ended December 31, 2016 were not met. As such, the Company recorded a gain during the period for the $1.4 million of contingent consideration. On May 3, 2016, the Company acquired certain assets of Solutions Recovery, Inc., its affiliates and associated real estate assets (collectively, “Solutions”) for total consideration of $6.8 million in cash and 309,871 of restricted shares of AAC Holdings’ common stock (the “Solutions Acquisition”). Solutions provides detoxification, residential and intensive outpatient treatment as well as sober living services in the greater Las Vegas, Nevada area. The purchase price was based upon arms-length negotiations between the Company and Solutions, an unrelated third party, that resulted in a premium to the fair value of the net assets acquired and, correspondingly, the recognition of goodwill. The amount recorded for goodwill is consistent with the Company’s intentions for the acquisition and is deductible for income tax purposes. Both the acquisitions of Townsend and Solutions (collectively “2016 Acquisitions”) were accounted for as business combinations in accordance with FASB ASC 805, Business Combinations The fair values of assets acquired and liabilities assumed, at the corresponding acquisition dates, were as follows (in thousands): Townsend Solutions Total Acquisition date April 1, 2016 May 3, 2016 Accounts receivable 1,149 898 2,047 Property and equipment 282 5,220 5,502 Goodwill 19,695 5,912 25,607 Intangible assets 1,200 1,228 2,428 Total assets acquired 22,326 13,258 35,584 Accrued liabilities 364 190 554 Net assets acquired $ 21,962 $ 13,068 $ 35,030 Total purchase price of acquisition $ 21,962 $ 13,068 $ 35,030 2015 Acquisitions During 2015, the Company acquired certain assets of the following entities, collectively referred to as the “2015 Acquisitions”.

The 2015 Credit Facility initially consisted of a $50.0 million revolving credit facility and a $75.0 million term loan. The Company incurred approximately $2.0 million in debt issuance costs related to underwriting and other professional fees, of which approximately $1.1 million related to the revolving credit loan and approximately $0.9 million related to the term loan. The Company deferred these costs over the term of the 2015 Credit Facility. On July 13, 2016, the Company increased its 2015 Credit Facility to $171.3 million, consisting of a $50.0 million revolving credit facility and a $121.3 million term loan. The facility is scheduled to mature in March 2020 and bears interest at LIBOR plus a margin between 2.25% to 3.75% or a base rate plus a margin between 1.25% and 2.75%, in each case depending on the Company’s leverage ratio. The facility has an accordion feature that provides for an additional $75.0 million of borrowing capacity under the credit facility, subject to certain consents and conditions, including obtaining additional commitments from lenders. As of December 31, 2016, the balance on the term loan was $118.8 million, and the balance on the revolving credit facility was $21.0 million. On February 27, 2017, the Company amended its 2015 Credit Facility, to, among other things, provide for certain modifications to the terms of the 2015 Credit Agreement, dated as of March 19, 2015, as amended from time to time (the “2015 Credit Agreement”), including the following: (i) extend the maximum Consolidated Total Leverage Ratio (as defined in the 2015 Credit Agreement) of 4:25:1.00 through the measurement period ending September 30, 2017; and (ii) amend the definition of Applicable Margin (as defined in the 2015 Credit Agreement) to add an additional pricing level of 3.75% for Eurodollar Rate Loans and Letter of Credit Fee, 2.75% for Base Rate Loans and 0.60% for Commitment Fee (as all such terms are defined in the 2015 Credit Agreement), which will be applicable when the Consolidated Total Leverage Ratio is equal to or exceeds 4.00:1.00 at the end of the applicable measuring period (the “New Pricing Level”) and to provide that the Applicable Rate (as defined in the 2015 Credit Agreement) be set at the New Pricing Level from the date of such amendment until the first business day following the date the Company delivers its next Compliance Certificate (as defined in the 2015 Credit Agreement). The amendment also provided for additional Adjusted EBITDA (as defined in the 2015 Credit Agreement) add backs under its covenant calculation to account for its February 2017 reduction in workforce. The 2015 Credit Facility requires quarterly term loan principal repayments for the outstanding term loan of $2.3 million for March 31, 2017 to December 31, 2017, $3.9 million from March 31, 2018 to December 31, 2018, and $4.7 million from March 31, 2019 to December 31, 2019, with the remaining principal balance of the term loan due on the maturity date of March 9, 2020. Repayment of the revolving loan is due on the maturity date of March 9, 2020. The 2015 Credit Facility generally requires quarterly interest payments, and limits our ability to pay dividends. Borrowings under the 2015 Credit Facility are guaranteed by the Company and each of its subsidiaries and are secured by a lien on substantially all of the Company’s and its subsidiaries’ assets. Borrowings under the 2015 Credit Facility bear interest at a rate tied to the Company’s Consolidated Total Leverage Ratio (defined as Consolidated Funded Indebtedness to Consolidated EBITDA, in each case as defined in the 2015 Credit Facility, as amended). Eurodollar Rate Loans with respect to the 2015 Credit Facility bear interest at the Applicable Rate plus the Eurodollar Rate (each as defined in the 2015 Credit Facility, as amended) (based upon the LIBOR Rate (as defined in the 2015 Credit Facility, as amended) prior to commencement of the interest rate period). Base Rate Loans with respect to the 2015 Credit Facility bear interest at the Applicable Rate plus the highest of (i) the federal funds rate plus 0.50%, (ii) the prime rate and (iii) the Eurodollar Rate plus 1.0% (the interest rate at December 31, 2016 was 4.25%). In addition, the Company is required to pay a commitment fee on undrawn amounts under the revolving loan of the 2015 Credit Facility of 0.35% to 0.60% depending on the Company’s Consolidated Total Leverage Ratio (the commitment fee rate at December 31, 2016 was 0.50%). The Applicable Rates and the unused commitment fees of the 2015 Credit Facility, after the February 27, 2017 amendment, are based upon the following tiers: Pricing Tier Consolidated Total Leverage Ratio Eurodollar Rate Loans Base Rate Loans Commitment Fee 1 > 3.75 % 2.75 % 0.60 % 2 > 3.25 % 2.25 % 0.50 % 3 > 3.00 % 2.00 % 0.45 % 4 > 2.75 % 1.75 % 0.40 % 5 > 2.50 % 1.50 % 0.35 % 6 < 2.00:1.00 2.25 % 1.25 % 0.35 % The 2015 Credit Facility requires the Company to comply with customary affirmative, negative and financial covenants, including a Consolidated Fixed Charge Coverage Ratio, Consolidated Total Leverage Ratio and a Consolidated Senior Secured Leverage Ratio (each as defined in the 2015 Credit Facility, as amended). The Company may be required to pay all of its indebtedness immediately if the Company defaults on any of the financial or other restrictive covenants contained in the 2015 Credit Facility. The financial covenants, after the February 27, 2017 amendment, include maintenance of the following: • Fixed Charge Coverage Ratio may not be less than 1.50:1.00 as of the end of any fiscal quarter. • Consolidated Total Leverage Ratio: may not be greater than the following levels as of the end of each fiscal quarter: Measurement Period Ending Maximum Consolidated Total Leverage Ratio December 31, 2016 4.25:1.00 March 31, 2017 4.25:1.00 June 30, 2017 4.25:1.00 September 30, 2017 4.25:1.00 December 31, 2017 and each fiscal quarter thereafter 4.00:1.00 • Consolidated Senior Secured Leverage Ratio may not be greater than the following levels as of the end of each fiscal quarter: Measurement Period Ending Maximum Consolidated Senior Secured Leverage Ratio December 31, 2016 3.75:1.00 March 31, 2017 and each fiscal quarter thereafter 3.50:1.00 At December 31, 2016, the Company was in compliance with all applicable covenants under the 2015 Credit Facility. In 2015, the Company incurred approximately $1.4 million in debt issuance costs related to underwriting and other professional fees, and deferred these costs over the term of the 2015 Credit Facility. As of December 31, 2016, total borrowings under the $50.0 million revolver portion of the 2015 Credit Facility were $21.0 million and $2.5 million in standby letters of credit issued for various corporate purposes resulting in $26.5 million available to the Company. 2015 Subordinated Debt On October 2, 2015, the Company entered into two financing facilities with affiliates of Deerfield Management Company, L.P. (“Deerfield”). The financing facilities consist of $25.0 million of subordinated convertible debt and up to $25.0 million of unsecured subordinated debt, together with an incremental facility of up to an additional $50.0 million of subordinated convertible debt (subject to certain conditions) (the “Deerfield Facility”). The Company issued $25.0 million of subordinated convertible debt at closing and used the proceeds to fund acquisitions, its de novo projects and for general corporate purposes. The $25.0 million of subordinated convertible debt bears interest at an annual rate of 2.50% and matures on September 30, 2021. The $25.0 million of subordinated convertible debt funded at closing is convertible into shares of the Company’s common stock at $30.00 per share. In the second quarter of 2016, the Company issued $25.0 million of the unsecured subordinated debt and used the proceeds to fund the acquisitions of Townsend, the hotel in Arlington, Texas and Solutions. The unsecured subordinated debt bears interest at an annual rate of 12.0% and matures on October 2, 2020. The Company incurred approximately $1.4 million in debt issuance costs related to underwriting and other professional fees and deferred these costs over the term of the debt. As of December 31, 2016, both the $25.0 million of subordinated convertible debt, bearing interest at 2.5%, and the $25.0 million of unsecured subordinated debt, bearing interest at 12.0%, were outstanding. Acquisition Related Debt At December 31, 2015, the Company had outstanding notes payables of $1.2 million resulting from the seller financing of the acquisition of certain assets of AJG Solutions and its subsidiaries and the equity of B&B Holdings INTL LLC (collectively, the “TSN Acquisition”). On February 29, 2016, the Company paid in full the outstanding balance, including principal of $1.2 million and accrued interest of $0.2 million. Interest Rate Swap Agreements In July 2014, the Company entered into two interest rate swap agreements to mitigate its exposure to fluctuations in interest rates. The interest rate swap agreements have notional amounts of $7.3 million and $10.8 million which fix the interest rates over the life of the respective swap agreement at 4.21% and 4.73%, and mature in May 2018 and August 2019, respectively. The notional amounts of the swap agreements represent amounts used to calculate the exchange of cash flows and are not the Company’s assets or liabilities. The interest payments under these agreements are settled on a net basis. The Company has not designated the interest rate swaps as cash flow hedges and therefore the changes in the fair value of the interest rate swaps are included within interest expense in the consolidated statements of operations. The fair value of the interest rate swaps at December 31, 2016 and 2015 represented a liability of $284,000 and $464,000, respectively, and is reflected in other long-term liabilities on the consolidated balance sheets. Refer to Note 15 for further discussion of fair value of the interest rate swap agreements. The Company’s credit risk related to these agreements is considered low because the swap agreements are with a creditworthy financial institution. A summary of future maturities of long-term debt, as of December 31, 2016, is as follows (in thousands): Years ending December 31, Non-Related Party Capital Lease Obligations Total 2017 $ 9,375 $ 774 $ 10,149 2018 15,625 716 16,341 2019 18,750 252 19,002 2020 96,000 — 96,000 2021 25,000 — 25,000 Thereafter 25,000 — 25,000 Total $ 189,750 $ 1,742 $ 191,492 Interest on outstanding amounts 33,921 103 34,024 Total, including interest $ 223,671 $ 1,845 $ 225,516

In connection with the 2013 exempt offering of AAC common stock, a Company employee subscribed for 19,090 shares of common stock at $5.24 per share, which the Company’s management estimated to be fair value. As consideration for the shares, the employee issued to the Company a subscription note receivable in the amount of $0.1 million.

During the year ended December 31, 2014, the Company recorded $58,000, respectively, in compensation expense related to this forgiveness. Stock Split On September 18, 2014, a 1.571119-for-1 stock split in the form of a stock dividend was effected.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	15. Fair Value of Financial Instruments The carrying amounts reported at December 31, 2016 and 2015 for cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued liabilities approximate fair value because of the short-term maturity of these instruments and are categorized as Level 1 within the GAAP fair value hierarchy. The fair value of the Company’s revolving line of credit is categorized as Level 2. The carrying amount of the Company’s debt approximates fair value because interest rates approximate the current rates available to the Company. The Company has debt with variable and fixed interest rates. The fair value of debt with fixed interest rates was determined using the quoted market prices of debt instruments with similar terms and maturities, which are considered Level 2 inputs. The fair value of debt with variable interest rates was also measured using other Level 2 inputs, including good faith estimates of the market value for the particular debt instrument, which represent the amount an independent market participant would provide, based upon market observations and other factors relevant under the circumstances. The carrying value of such debt approximated its estimated fair value at December 31, 2016 and 2015. The Company has entered into interest rate swap agreements to manage exposure to fluctuations in interest rates. Fair value of the interest rate swaps is determined using a pricing model based on published interest rates and other observable market data. The fair value was determined after considering the potential impact of collateralization, adjusted to reflect both the Company’s own nonperformance risk and the respective counterparty’s nonperformance risk. The fair value measurement of interest rate swaps utilizes Level 2 inputs. At each of December 31, 2016 and 2015, the fair value of the interest rate swaps represented a liability of $0.3 million and $0.5 million, respectively. Refer to Note 9 for further discussion of the interest rate swap agreements. Intangible assets are measured at fair value on a non-recurring basis. These assets are classified in Level 3 of the fair value hierarchy. Goodwill and other indefinite-lived intangibles are tested for impairment at least annually, or more frequently if circumstances indicate that the carrying amount exceeds fair value. The Company estimates the fair values of goodwill and other indefinite-lived intangibles utilizing multiple measurement techniques. The estimation is primarily determined based on an estimate of future cash flows (income approach) discounted at a market derived weighted-average cost of capital. The income approach has been determined to be the most representative of fair value because the Company’s equity does not have an active trading market. Other unobservable inputs used in these valuations include management’s cash flow projections and estimated terminal growth rates. The valuation of indefinite-lived intangible assets also includes an unobservable input for royalty rate, which is based on rates used by comparable industries. The useful lives of definite-lived intangible assets (customer relationships) are evaluated whenever events or circumstances warrant a revision to the remaining amortization period. The fair value of definite-lived intangible assets is based on estimated cash flows from the future use of the asset, discounted at a market derived weighted-average cost of capital. No impairment charges were recorded related to goodwill or other intangible assets for the years ended December 31, 2016, 2015, and 2014. Long-lived assets are measured at fair value on a non-recurring basis and are classified in Level 3 of the fair value hierarchy. The fair value is estimated utilizing unobservable inputs, including appraisals on real estate as well as evaluations of the marketability and potential relocation of other assets in similar condition and similar market areas. The Company analyzes long-lived assets on an annual basis for any triggering events that would necessitate an impairment test. No impairment charges were recorded for the years ended December 31, 2016, 2015, and 2014.

(formerly known as Forterus, Inc.), Forterus Health Care Services, Inc., and ABTTC, Inc. (collectively, the “Defendants,” each of which is a direct or indirect subsidiary of AAC Holdings) agreed to the entry of a Permanent Injunction and Final Judgment (the “PIFJ”) with the Bureau of Medi-Cal Fraud and Elder Abuse of the Office of the Attorney General of the State of California (“BMFEA”) relating to the criminal charges filed against the Defendants in connection with the death of a client in 2010 at one of the Company’s former locations. The PIFJ generally provides, among other things and subject to certain limitations, that the State of California (i) dismiss all criminal charges against the Defendants in connection with the case entitled People v. McCausland, et al. Pursuant to the terms of the PIFJ, among other things and subject to certain limitations, Defendants shall (i) institute a three-year compliance program (the “Compliance Program”) with respect its California facilities that includes, to the extent not already established, that certain policies and procedures are maintained or developed and implemented to promote each covered facility’s compliance with applicable statutes, regulations and the PIFJ, under the responsibility of AAC Holdings’ Chief Compliance Officer; (ii) establish a Compliance Committee composed of the Compliance Officer and senior personnel responsible for overseeing clinical operations to address issues raised by the Compliance Officer in connection with the Compliance Program and (iii) establish an oversight committee of its board of directors (the “Board”), or a committee of the Board, to review the adequacy and responsiveness of the Compliance Program. In addition, for a period of 30 months following the effective date of the PIFJ, the Defendants shall retain a qualified independent monitor, appointed by BMFEA after consultation with the Defendants, to assess the effectiveness of the Defendants’ quality control systems and patient care. The PIFJ also provides that the Defendants will pay $549,986 toward the costs of the investigation and $200,000 as a civil monetary penalty, the total of which was accrued for and paid in full in 2016 and is included in litigation settlement on the statement of operations.

All felony charges were also dismissed against Jerrod Menz and James Fent, and their criminal cases were resolved pursuant to their agreements not to contest misdemeanor charges, which will ultimately be eligible for dismissal upon their satisfying certain conditions required by the court. Shareholder Litigation On August 24, 2015, a shareholder filed a purported class action in the United States District Court for the Middle District of Tennessee against the Company and certain of its current and former officers ( Kasper v. AAC Holdings, Inc. et al. and Tenzyk c. AAC Holdings, Inc. et al.) Bushansky v. Jerrod N. Menz et al.)

Based on these discussions, the Company has recorded an aggregate $350,000 reserve related to this matter and included in litigation settlement on the statement of operations. Horizon Blue Cross Blue Shield of New Jersey v. Avee Laboratories et al. On September 4, 2013, Horizon Blue Cross Blue Shield of New Jersey (“Horizon”) filed an amended complaint in the Superior Court of New Jersey against several defendants, including Leading Edge Recovery Center, LLC, one of the Company’s subsidiaries. Leading Edge Recovery Center, LLC formerly operated a drug and alcohol treatment facility in New Jersey. Horizon alleges the defendants submitted and caused others to submit unnecessary drug tests in violation of New Jersey law and is seeking recovery for monetary and treble damages. The parties have reached a confidential settlement in this matter and consider it closed. The Company recognized $2.2 million of expense in litigation settlement related to this matter during 2015. Upon execution of the settlement, the Company made a payment of $1.2 million and agreed to pay $0.1 million per month until the full settlement amount has been paid in full. The settlement was paid in full during 2016, resulting in no remaining balance outstanding as of December 31, 2016, compared to $0.8 million as of December 31, 2015. Bevell Settlement On February 3, 2014, AAC filed an action against James D. Bevell in the U.S. District Court in the Middle District of Tennessee, alleging breach of contract and tortious interference with business practices arising out of Mr. Bevell’s breach of his non-compete agreements. Mr. Bevell is the former Chief Innovation Officer of AAC. On July 16, 2014, Mr. Bevell filed an action, for which an amended complaint was filed on August 15, 2014, in the Chancery Court for the State of Tennessee in Williamson County which alleged the defendants breached fiduciary duties owed to Mr. Bevell and breached the Agreement Among Stockholders entered into in connection with the TSN Acquisition. On August 15, 2014, AAC, entered into settlement agreements to resolve all outstanding disputes among the parties (the “Bevell Settlement”). Pursuant to the terms of the Bevell Settlement, the Company agreed to pay Mr. Bevell the sum of approximately $7.6 million. In addition, pursuant to the terms of the Bevell Settlement, the Company eliminated the debt payable to Mr. Bevell of $1.9 million and Mr. Bevell surrendered 698,259 shares ($5.7 million) of AAC common stock that were subsequently cancelled. There was no impact to the Company’s consolidated statement of operations as a result of the Bevell Settlement. Other The Company is aware of various other legal matters arising in the ordinary course of business. To cover these types of claims, the Company maintains insurance it believes to be sufficient for its operations, although some claims may potentially exceed the scope of coverage in effect. Plaintiffs in these matters may request punitive or other damages that may not be covered by insurance. After taking into consideration the evaluation of such matters by the Company’s legal counsel, the Company’s management believes the outcome of these matters will not have a material impact on the Company’s consolidated financial position, results of operations and cash flows. Other Commitments and Contingencies Effective February 3, 2017, Candance Henderson-Grice, resigned from her then current positions as Chief Operating Officer of Holdings and as Chief Operating Officer of AAC.

Summary of Significant Accoun26

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of consolidated 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, liabilities, revenues and expenses at the date and for the periods that the consolidated financial statements are prepared. On an ongoing basis, the Company evaluates its estimates, including those related to insurance adjustments, provisions for doubtful accounts, goodwill and intangible assets, long-lived assets, deferred revenues and income taxes. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could materially differ from those estimates.
General and Administrative Costs	General and Administrative Costs The majority of the Company’s expenses are “cost of revenue” items. Costs that could be classified as general and administrative expenses include the Company’s corporate overhead costs, which were $74.8 million, $48.2 million, and $25.3 million for the years ended December 31, 2016, 2015, and 2014, respectively.
Client Related Revenues	Client Related Revenues The Company provides services to its clients in both inpatient and outpatient treatment settings. Client related revenues are recognized when services are performed at estimated net realizable value from clients, third-party payors and others for services provided. The Company receives the majority of payments from commercial payors at out-of-network rates. Client related revenues are recorded at established billing rates less adjustments to estimate net realizable value. Adjustments are recorded to state client service revenues at the amount expected to be collected for the service provided based on historic adjustments for out-of-network services not under contract. Prior to admission, each client’s insurance is verified and the client self-pay amount is determined. The client self-pay portion is generally collected upon admission. In some instances, clients will pay out-of-pocket as services are provided or will make a deposit and negotiate the remaining payments as part of the services. These out-of-pocket payments are included in accrued liabilities in the accompanying consolidated balance sheets and revenues related to these payments are deferred and recognized over the period services are provided. From time to time, scholarships may be provided to a limited number of clients. The Company does not recognize revenues for care provided via scholarships. For the year ended December 31, 2016, approximately 10.5% of the Company’s revenue reimbursements came from Blue Cross Blue Shield of Florida, 10.4% came from Blue Cross Blue Shield of Texas, and 10.4% came from Aetna. No other payor accounted for more than 10% of the Company’s revenue reimbursements for the year ended December 31, 2016. For the year ended December 31, 2015, approximately 15.1% of the Company’s revenues were reimbursed by Anthem Blue Cross Blue Shield of Colorado; 12.5% by Blue Cross Blue Shield of Texas; 11.5% by Aetna, and 11.1% were reimbursed by Blue Cross Blue Shield of California. No other payor accounted for more than 10% of revenue reimbursements for the year ended December 31, 2015. For the year ended December 31, 2014, approximately 18.1% of the Company’s revenue reimbursements came from Anthem Blue Cross Blue Shield of Colorado, 13.3% came from Blue Cross Blue Shield of Texas, 12.9% came from Aetna, 10.5%
Other Revenues	Other Revenue The Company’s other revenue consists of service charges from the delivery of quality targeted leads to behavioral and mental health service businesses through the Company’s operating subsidiary Referral Solutions Group, LLC, which was acquired on July 2, 2015, and diagnostic laboratory services provided to clients of third-party addiction treatment providers
Allowance for Contractual and Other Discounts	Allowance for Contractual and Other Discounts The Company derives the majority of its revenues from commercial payors at out-of-network rates. Management estimates the allowance for contractual and other discounts based on its historical collection experience. The services authorized and provided and related reimbursement are often subject to interpretation and negotiation that could result in payments that differ from the Company’s estimates.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable primarily consists of amounts due from third-party payors (non-governmental) and is recorded net of contractual discounts. The Company’s ability to collect outstanding receivables is critical to its results of operations and cash flows. Accounts receivable is reported net of an allowance for doubtful accounts, which is management’s best estimate of accounts receivable that could become uncollectible in the future. Accordingly, accounts receivable reported in the Company’s consolidated financial statements is recorded at the net amount expected to be received. The Company’s primary collection risks are (i) the risk of overestimating net revenues at the time of billing that may result in the Company receiving less than the recorded receivable, (ii) the risk of non-payment as a result of commercial insurance companies denying claims, (iii) the risk that clients will fail to remit insurance payments to the Company when the commercial insurance company pays out-of-network claims directly to the client and (iv) resource and capacity constraints that may prevent the Company from handling the volume of billing and collection issues in a timely manner, (v) the risk that clients do not pay the Company for their self-pay balance (including co-pays, deductibles and any portion of the claim not covered by insurance) and (vi) the risk of non-payment from uninsured clients. The Company’s allowance for doubtful accounts is based on historical experience, but management also takes into consideration the age of accounts, creditworthiness and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. Approximately $10.4 million of the accounts receivable, net the of the allowance for doubtful accounts, at December 31, 2016 includes accounts where the Company has received a partial payment from a commercial insurance company and the Company is continuing to pursue additional collections for the balance that the Company estimates remains outstanding. At December 31, 2016, 11.6% of accounts receivable was from Anthem Blue Cross Blue Shield of Colorado and 10.3% was from Anthem Blue Cross Blue Shield of California. At December 31, 2015, 22.4% of accounts receivable was from Anthem Blue Cross Blue Shield of Colorado and 15.0% was from Blue Cross Blue Shield of California. No other payor accounted for more than 10% of accounts receivable at December 31, 2016 or 2015. A summary of activity in the Company’s allowance for doubtful accounts is as follows (in thousands): Balance at December 31, 2013 $ 13,320 Additions charged to provision for doubtful accounts 11,391 Accounts written off, net of recoveries (16,243 ) Balance at December 31, 2014 $ 8,468 Additions charged to provision for doubtful accounts 18,113 Accounts written off, net of recoveries (9,704 ) Balance at December 31, 2015 $ 16,877 Additions charged to provision for doubtful accounts 21,485 Accounts written off, net of recoveries (10,234 ) Balance at December 31, 2016 $ 28,128
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents.
Property, Plant and Equipment	Property and Equipment Property and equipment are stated at cost or at acquisition date fair value for assets obtained in business combinations, net of accumulated depreciation and amortization. Expenditures for maintenance and repairs are charged to expense as incurred. The Company capitalizes interest on construction projects and such interest is included in the cost of the related asset. Assets held for development are classified as construction in progress and the Company does not depreciate these assets until they are placed in service. Leasehold improvements are amortized over their estimated useful lives or the remaining lease period, whichever is less. Assets under capital leases are amortized over the lease term or in the event of transfer of ownership at the end of the lease over the economic life of the leased asset. Amortization expense related to assets under capital lease is included with depreciation and amortization expense in the consolidated statements of operations. Depreciation is calculated using the straight-line method over the estimated economic useful lives of the assets, as follows: Range of Lives Computer software and equipment 3 years Buildings 36 years Furniture, fixtures and equipment 5 years Vehicles 5 years Equipment under capital lease 3-5 years Leasehold improvements Life of the asset or lease, whichever is less
Goodwill and Intangible Assets	Goodwill and Intangible Assets The Company has only one operating segment, substance abuse/behavioral healthcare treatment services, for segment reporting purposes. The substance abuse/behavioral healthcare treatment services operating segment represents one reporting unit for purposes of the Company’s goodwill impairment test. Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired. Goodwill and intangible assets with indefinite lives are not amortized, but instead are tested for impairment at least annually or whenever events or changes in circumstances indicate the carrying value may not be recoverable. If the carrying value of goodwill exceeds its implied fair value, an impairment loss is recorded. The Company’s annual impairment tests of goodwill and other indefinite-lived intangibles in 2016 and 2015 resulted in no impairment charges. The Company’s other intangible assets principally relate to trademarks, marketing intangibles, non-compete agreements, and leasehold interests acquired during business combinations. Trademarks and marketing intangibles are amortized over a period of ten years, non-compete agreements are amortized over the term of the agreements, and leasehold interests are amortized over the remaining life of the leases.
Long-Lived Asset Impairment	Long-Lived Asset Impairment Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net undiscounted cash flows expected to be generated by the asset. Impairment is measured by the amount by which the carrying value of the assets exceeds the fair value of the assets. The Company did not identify any indicators of impairment during the years ended December 31, 2016 and 2015.
Accrued Liabilities	Accrued Liabilities The Company’s accrued liabilities, reflected as a current liability in the accompanying consolidated balance sheets, consist of the following (in thousands): Year Ended December 31, 2016 2015 Accrued payroll liabilities 13,501 $ 10,090 Accrued litigation settlement 962 800 Accrued legal fees 915 479 Income taxes payable 244 2,527 Accrued property, plant, and equipment 2,650 1,487 Other 8,470 6,270 Total accrued liabilities $ 26,742 $ 21,653
Segments	Segments The focus of all Company operations is centered on a single service, substance abuse/behavioral healthcare treatment. As such, the Company has one operating segment. The Company is organized and operates as one reportable segment, consisting of various treatment facilities located in the United States. The treatment facilities operate in the same industry and have similar economic characteristics, services and clients. Management has the ability to direct and serve clients in any of these facilities, which allows management to operate the Company’s business and analyze its revenues on a system-wide basis rather than focusing on any individual facility. The Company’s chief operating decision maker evaluates performance and manages resources based on the results of the consolidated operations as a whole.
Advertising Expenses	Advertising Expenses Advertising costs are expensed as the related activity occurs.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation to employees using a fair-value based method for costs related to all share-based payments. Prior to the Company’s stock being traded in an active market, the Company estimated the fair value of employee restricted stock awards on the date of grant based on the appraised fair value. The fair value of the portion of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the requisite service periods in the Company’s consolidated statements of operations.
Earnings Per Share	Earnings Per Share Basic and diluted earnings per common share are calculated based on the weighted-average number of common shares outstanding in each period and dilutive stock options, non-vested shares, convertible debt securities, and warrants, to the extent such securities have a dilutive effect on earnings per share using the treasury stock method.
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on the deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for significant deferred tax assets when it is more likely than not that such assets will not be recovered. The Company’s practice is to recognize interest and/or penalties related to uncertain income tax positions in income tax expense. For the years ended December 31, 2016, 2015 and 2014, the Company had no accrued interest or penalties related to income tax matters. VIEs included in the accompanying consolidated financial statements consist of various corporations and a partnership. As discussed in Note 3, the Company acquired BHR on April 15, 2014, prior to that date, BHR was a partnership for income tax purposes. Partnerships are characterized as flow through entities for federal and certain state income tax purposes, taxes for the VIEs that are considered partnerships are not recorded in the accompanying consolidated financial statements, except for certain state taxes imposed at the entity level. Taxes that are imposed on the owners of these partnerships are not included in the accompanying consolidated financial statements. Taxes attributable to BHR after the acquisition date are included in these consolidated financial statements.
Fair Value Measurements	Fair Value Measurements Fair value, for financial reporting purposes, is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Disclosure is required about how fair value was determined for assets and liabilities and following a hierarchy for which these assets and liabilities must be grouped, based on significant levels of inputs as follows: Level 1—quoted prices in active markets for identical assets or liabilities; Level 2—quoted prices in active markets for similar assets and liabilities and inputs that are observable for the asset or liability; or Level 3—unobservable inputs for the asset or liability, such as discounted cash flow models or valuations. The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
Comprehensive Income	Comprehensive Income As of December 31, 2016, 2015, and 2014, the Company did not have any components of other comprehensive income. As such, comprehensive income equaled net income for each of the periods presented in the accompanying consolidated statements of operations.
Recent Pronouncements	Recent Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). The new guidance eliminates the requirement to calculate the implied fair value of goodwill (i.e., Step 2 of the current goodwill impairment test) to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (i.e., measure the charge based on the current Step 1). ASU 2017-04 is effective for annual and any interim impairment tests for periods beginning after December 15, 2019. The Company is currently evaluating the provisions of ASU 2017-04 to determine the impact on the Company’s financial statements. In August 2016, the FASB issued (“ASU”) No. 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). Among other clarifications, ASU 2016-15 clarifies certain items, including the classification of payments for debt prepayment or debt extinguishment costs, including third-party costs, premiums paid, and other fees paid to lenders that are directly related to the debt prepayment or debt extinguishment, excluding accrued interest, which will now be included in the Financing Activities section in the Statements of Cash Flows. The new standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-15 is not expected to have a material impact on the Company’s results of operations. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses: Measurement of Credit Losses In March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 requires that all excess tax benefits and tax deficiencies resulting from share-based payments be recognized as income tax expense or benefit in the income statement, which eliminates the accounting for additional paid-in capital pools. ASU 2016-09 also allows companies to make an entity-wide policy election to either estimate the number of stock-based awards that are expected to vest or account for forfeitures as they occur. With regards to the Statement of Cash Flows, both inflows and outflows of cash related to excess tax benefits will be classified as operating activities, whereas prior to this update, excess tax benefits as cash inflows were to be classified as financing activities. Also, cash paid by an employer when directly withholding shares for tax-withholding purposes (“net share settlement”) will now be classified as a financing activity. The new standard is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is in the early stages of evaluating the impact that adoption of this new standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases”. The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company anticipates that the adoption of ASU 2016-2 will result in an increase in both total assets and total liabilities. In November 2015, the FASB issued ASU 2015-17, “Income Taxes: Balance Sheet Classification of Deferred Taxes” (“ASU 2015-17”). ASU 2015-17 requires deferred tax assets and liabilities to be netted and presented as a single non-current amount in the balance sheet, rather than separating them into current and non-current amounts. The Company prospectively adopted the provisions of ASU 2015-17 during the fourth quarter of 2015. Prior periods were not retrospectively adjusted. The adoption of ASU 2015-17 had no impact on the Company’s results of operations or cash flows. In September 2015, the FASB issued ASU 2015-16, “Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments” (“ASU 2015-16”). ASU 2015-16 eliminates the requirement for an acquirer to retrospectively adjust its financial statements for changes to provisional amounts that are identified during the measurement-period following the consummation of a business combination. Instead, ASU 2015-16 requires these types of adjustments to be made during the reporting period in which they are identified and would require additional disclosure or separate presentation of the portion of the adjustment that would have been recorded in the previously reported periods as if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective prospectively for fiscal years beginning after December 15, 2015, including interim periods within those years, . The adoption of ASU 2015-16 did not have a material impact on the Company’s results of operations. In April 2015, the FASB issued ASU No. 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software.” The update was effective for financial statements issued for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years, with early adoption permitted. ASU 2015-05 provides guidance for customer’s accounting for fees paid in a cloud computing arrangement. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. An entity can elect to adopt the amendments either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. The adoption of ASU 2015-05 on January 1, 2016 did not have a material impact on the Company’s consolidated financial statements. In March 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs”. The update is effective for financial statements issued for fiscal years beginning after December 15, 2015, and those interim periods within those fiscal years, with early adoption permitted. The update requires debt issuance costs related to a note to be reported in the balance sheet as a direct deduction from the face amount of that note on a retrospective basis upon adoption. The Company elected to early adopt the revised guidance and presented $1.9 million of deferred debt issuance costs associated with the Company’s 2015 Credit Facility (as later defined) net of the debt balance at December 31, 2015 (see Note 9). In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers”, which outlines a single comprehensive model for recognizing revenue and supersedes most existing revenue recognition guidance, including guidance specific to the healthcare industry. Updates to this standard have been issued subsequent to the initial ASU 2014-09. Companies across all industries will use a new five-step model to recognize revenue from customer contracts. The new standard, which replaces nearly all existing GAAP revenue recognition guidance, will require significant management judgment in addition to changing the way many companies recognize revenue in their financial statements. The standard is effective for public entities for annual and interim periods beginning after December 15, 2017, with early adoption permitted for annual periods beginning after December 15, 2016. As the Company progresses with its implementation efforts to adopt ASU 2014-09, management continues to evaluate and refine its estimates of the anticipated impact the new standard will have on its revenue recognition policies, procedures, financial position, results of operations, cash flows and financial disclosures. Specifically, the Company is continuing to evaluate the impact the adoption will have on the presentation of the provision for doubtful accounts in the consolidated statements of operations and whether some or all of the provision for doubtful accounts will continue to be presented as a separate line item or will be recorded as a direct reduction to revenues.
