Accounting Policies [Abstract]
Description of Business and Basis of Presentation	1. Description of Business and Basis of Presentation Description of Business Acadia Healthcare Company, Inc. (the “Company”) develops and operates inpatient psychiatric facilities, residential treatment centers, group homes, substance abuse facilities and facilities providing outpatient behavioral healthcare services to serve the behavioral health and recovery needs of communities throughout the United States (“U.S.”), the United Kingdom (“U.K.”) and Puerto Rico. At June 30, 2019, the Company operated 595 behavioral healthcare facilities with approximately 18,200 beds in 40 states, the U.K. and Puerto Rico. During the six months ended June 30, 2019, the Company commenced a review of strategic alternatives including those related to its U.K. operations and a potential sale of such operations. The likelihood and form of strategic alternative that the Company may pursue for its U.K. operations remains uncertain. Basis of Presentation The business of the Company is conducted through limited liability companies, partnerships and C-corporations. The Company’s consolidated financial statements include the accounts of the Company and all subsidiaries controlled by the Company through its direct or indirect ownership of majority interests and exclusive rights granted to the Company as the controlling member of an entity. All intercompany accounts and transactions have been eliminated in consolidation. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation of our financial position and results of operations have been included. The Company’s fiscal year ends on December 31 and interim results are not necessarily indicative of results for a full year or any other interim period. The condensed consolidated balance sheet at December 31, 2018 has been derived from the audited financial statements as of that date. The information contained in these condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto for the fiscal year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 1, 2019. 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. Certain reclassifications have been made to prior years to conform to the current year presentation.

Revenue From Contract With Customer [Abstract]
Revenue	3. Revenue Revenue is primarily derived from services rendered to patients for inpatient psychiatric and substance abuse care, outpatient psychiatric care and residential treatment. The services provided by the Company have no fixed duration and can be terminated by the patient or the facility at any time, and therefore, each treatment is its own stand-alone contract. As our performance obligations relate to contracts with a duration of one year or less, the Company elected the optional exemption in Accounting Standards Codification (“ASC”) ASC 606-10-50-14(a). Therefore, the Company is not required to disclose the transaction price for the remaining performance obligations at the end of the reporting period or when the Company expects to recognize the revenue. The Company has minimal unsatisfied performance obligations at the end of the reporting period as our patients typically are under no obligation to remain admitted in our facilities. The Company disaggregates revenue from contracts with customers by service type and by payor within each of the Company’s segments. U.S. Facilities The Company’s facilities in the United States (the “U.S. Facilities”) and services provided by the U.S. Facilities can generally be classified into the following categories: acute inpatient psychiatric facilities; specialty treatment facilities; residential treatment centers; and outpatient community-based facilities. Acute inpatient psychiatric facilities. Acute inpatient psychiatric facilities provide a high level of care in order to stabilize patients that are either a threat to themselves or to others. The acute setting provides 24-hour observation, daily intervention and monitoring by psychiatrists. Specialty treatment facilities . Specialty treatment facilities include residential recovery facilities, eating disorder facilities and comprehensive treatment centers. The Company provides a comprehensive continuum of care for adults with addictive disorders and co-occurring mental disorders. Inpatient, including detoxification and rehabilitation, partial hospitalization and outpatient treatment programs give patients access to the least restrictive level of care. Residential treatment centers . Residential treatment centers treat patients with behavioral disorders in a non-hospital setting, including outdoor programs. The facilities balance therapy activities with social, academic and other activities. Outpatient community-based facilities . Outpatient community-based programs are designed to provide therapeutic treatment to children and adolescents who have a clinically-defined emotional, psychiatric or chemical dependency disorder while enabling the youth to remain at home and within their community. The table below presents total U.S. revenue attributed to each category (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Acute inpatient psychiatric facilities $ 229,128 $ 203,535 $ 445,725 $ 399,426 Specialty treatment facilities 201,269 192,894 394,304 377,429 Residential treatment centers 74,084 74,133 147,308 145,690 Outpatient community-based facilities 5,332 10,908 10,436 21,330 Revenue $ 509,813 $ 481,470 $ 997,773 $ 943,875 The Company receives payments from the following sources for services rendered in our U.S. Facilities: (i) state governments under their respective Medicaid and other programs; (ii) commercial insurers; (iii) the federal government under the Medicare program administered by the Centers for Medicare and Medicaid Services (“CMS”); and (iv) individual patients and clients. The Company determines the transaction price based on established billing rates reduced by contractual adjustments provided to third-party payors, discounts provided to uninsured patients and implicit price concessions. Contractual adjustments and discounts are based on contractual agreements, discount policies and historical experience. Implicit price concessions are based on historical collection experience. Most of our U.S. Facilities have contracts containing variable consideration. However, it is unlikely a significant reversal of revenue will occur when the uncertainty is resolved, and therefore, the Company has included the variable consideration in the estimated transaction price.

Healthcare facilities . Healthcare facilities provide psychiatric treatment and nursing for sufferers of mental disorders, including for patients whose risk of harm to others and risk of escape from hospitals cannot be managed safely within other mental health settings. In order to manage the risks involved with treating patients, the facility is managed through the application of a range of security measures depending on the level of dependency and risk exhibited by the patient. Education and children’s services. Education and children’s services provide specialist education for children and young people with special educational needs, including autism, Asperger’s Syndrome, social, emotional and mental health, and specific learning difficulties, such as dyslexia. The division also offers standalone children’s homes for children that require 52-week residential care to support complex and challenging behavior and fostering services. Adult care facilities . Adult care focuses on care of individuals with a variety of learning difficulties, mental health illnesses and adult autism spectrum disorders. It also includes long-term, short-term and respite nursing care to high-dependency elderly individuals who are physically frail or suffering from dementia. Care is provided in a number of settings, including in residential care homes and through supported living.

Leases

Leases [Abstract]
Leases	8 . The Company’s lease portfolio primarily consists of finance and operating real estate leases integral for facility operations. The original terms of the leases typically range from five to 30 years with optional renewal periods. A minimal portion of the Company’s lease portfolio consists of non-real estate leases, including copiers and equipment, which generally have lease terms of one to three years and have insignificant lease obligations. In March 2016, the FASB issued ASU 2016-02. ASU 2016-02’s core principle is to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information. The Company adopted ASU 2016-02 retrospectively at the beginning of the period of adoption. Prior periods have not been adjusted. The Company has elected the package of practical expedients offered in the transition guidance which allows management not to reassess lease identification, lease classification and initial direct costs. The Company also elected the accounting policy practical expedients by class of underlying asset to: (i) combine associated lease and non-lease components into a single lease component; and (ii) exclude recording short-term leases as right-of-use assets and liabilities on the condensed consolidated balance sheets. Non-lease components, which are not significant overall, are combined with lease components. On January 1, 2019, the Company recorded right-of-use assets and lease liabilities on the condensed consolidated balance sheet of $500.3 million and $526.6 million, respectively, for non-cancelable real estate operating leases with original lease terms in excess of one year. Finance leases remained on the condensed consolidating balance sheets as required by previous accounting guidance. The Company reviews service agreements for embedded leases and records right-of-use assets and liabilities as necessary. Operating lease liabilities were recorded as the present value of remaining lease payments not yet paid for the lease term discounted using the incremental borrowing rate associated with each lease. Operating lease right-of-use assets represent operating lease liabilities adjusted for prepayments, accrued lease payments, lease incentives and initial direct costs. Certain of the Company’s leases include renewal or termination options. Calculation of operating lease right-of-use assets and liabilities include the initial lease term unless it is reasonably certain a renewal or termination option will be exercised. Variable components of lease payments fluctuating with a future index or rate, as well as those related to common area maintenance costs, are not included in determining lease payments and are expensed as incurred. Most of the Company’s leases do not contain implicit borrowing rates, and therefore, incremental borrowing rates were calculated based on information available at the later of the lease commencement date or January 1, 2019. Incremental borrowing rates reflect the Company’s estimated interest rates for collateralized borrowings over similar lease terms. Lease Position At June 30, 2019, the Company recorded the following on the condensed consolidated balance sheet (in thousands): Right-of-Use Assets Balance Sheet Classification June 30, 2019 Finance lease right-of-use assets Property and equipment, net $ 44,981 Operating lease right-of-use assets Operating lease right-of-use assets 491,551 Total $ 536,532 Lease Liabilities Balance Sheet Classification June 30, 2019 Current: Finance lease liabilities Other accrued liabilities $ 7,095 Operating lease liabilities Current portion of operating lease liabilities 27,578 Noncurrent: Finance lease liabilities Other liabilities 44,088 Operating lease liabilities Operating lease liabilities 490,903 Total $ 569,664 Weighted-average remaining lease terms and discount rates at June 30, 2019 were as follows: Weighted-average remaining lease term (in years): Finance 7.2 Operating 19.7 Weighted-average discount rate: Finance 6.4 % Operating 6.4 % Lease Costs The Company recorded the following lease costs for the three and six months ended June 30, 2019 (in thousands): Three Months Ended June 30, 2019 Six Months Ended June 30, 2019 Finance lease costs: Depreciation of leased assets 1,136 2,259 Interest of lease liabilities 999 1,996 Total finance lease costs $ 2,135 $ 4,255 Operating lease costs 16,237 32,766 Variable lease costs 1,044 1,930 Short term lease costs 1,483 2,930 Other lease costs 1,655 3,100 Total rents and leases $ 20,419 $ 40,726 Total lease costs $ 22,554 $ 44,981 Other Undiscounted cash flows for finance and operating leases recorded on the condensed consolidated balance sheet were as follows at June 30, 2019 (in thousands): Finance Leases Operating Leases For the six months ending December 31, 2019 $ 4,137 $ 30,201 2020 6,938 58,325 2021 35,101 54,702 2022 2,193 50,007 2023 1,063 46,511 Thereafter 26,094 708,139 Total minimum lease payments 75,526 947,885 Less: amount of lease payments representing interest 24,343 429,404 Present value of future minimum lease payments 51,183 518,481 Less: Current portion of lease liabilities 7,095 27,578 Noncurrent lease liabilities $ 44,088 $ 490,903 Supplemental data for the six months ended June 30, 2019 was as follows (in thousands): Six Months Ended June 30, Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows for operating leases $ 31,212 Operating cash flows for finance leases $ 1,996 Financing cash flows for finance leases $ 1,684 Right-of-use assets obtained in exchange for lease obligations: Operating leases $ 10,674 Finance leases $ 1,774

On December 31, 2012, the Company entered into an Amended and Restated Credit Agreement (the “Amended and Restated Credit Agreement”) which amended and restated the Senior Secured Credit Facility (the “Amended and Restated Senior Credit Facility”). The Company has amended the Amended and Restated Credit Agreement from time to time as described in the Company’s prior filings with the SEC. On March 22, 2018, the Company entered into a Second Repricing Facilities Amendment (the “Second Repricing Facilities Amendment”) to the Amended and Restated Credit Agreement. The Second Repricing Facilities Amendment (i) replaced the Term Loan B Facility Tranche B-1 (the “Tranche B-1 Facility”) and the Term Loan B Facility Tranche B-2 (the “Tranche B-2 Facility”) with a new Term Loan B facility Tranche B-3 (the “Tranche B-3 Facility”) and a new Term Loan B facility Tranche B-4 (the “Tranche B-4 Facility”), respectively, and (ii) reduced the Applicable Rate from 2.75% to 2.50% in the case of Eurodollar Rate loans and reduced the Applicable Rate from 1.75% to 1.50% in the case of Base Rate Loans. On March 29, 2018, the Company entered into a Third Repricing Facilities Amendment to the Amended and Restated Credit Agreement (the “Third Repricing Facilities Amendment”, and together with the Second Repricing Facilities Amendment, the “Repricing Facilities Amendments”). The Third Repricing Facilities Amendment replaced the existing revolving credit facility and Term Loan A facility (“TLA Facility”) with a new revolving credit facility and TLA Facility, respectively. The Company’s line of In connection with the Repricing Facilities Amendments, the Company recorded a debt extinguishment charge of $0.9 million, including the discount and write-off of deferred financing costs, which was recorded in debt extinguishment costs in the condensed consolidated statements of income. On February 6, 2019, the Company entered into the Eleventh Amendment (the “Eleventh Amendment”) to the Amended and Restated Credit Agreement. The Eleventh Amendment, among other things, amended the definition of “Consolidated EBITDA” to remove the cap on non-cash charges, losses and expenses related to the impairment of goodwill, which in turn provided increased flexibility to the Company in terms of the Company’s financial covenants. On February 27, 2019, the Company entered into the Twelfth Amendment (the “Twelfth Amendment”) to the Amended and Restated Credit Agreement. The Twelfth Amendment, among other things, modified certain definitions, including “Consolidated EBITDA”, and increased our permitted Maximum Consolidated Leverage Ratio, thereby providing increased flexibility to the Company in terms of the Company’s financial covenants. The Company had $422.4 million of availability under the revolving line of credit and had standby letters of credit outstanding of $12.6 million related to security for the payment of claims required by its workers’ compensation insurance program at June 30, 2019. Borrowings under the revolving line of credit are subject to customary conditions precedent to borrowing. The Amended and Restated Credit Agreement requires quarterly term loan principal repayments of our TLA Facility of $4.8 million for September 30, 2019 to December 31, 2019, $7.1 million for March 31, 2020 to December 31, 2020, and $9.5 million for March 31, 2021 to September 30, 2021, with the remaining principal balance of the TLA Facility due on the maturity date of November 30, 2021. The Company is required to repay the Tranche B-3 Facility in equal quarterly installments of $1.2 million on the last business day of each March, June, September and December, with the outstanding principal balance of the Tranche B-3 Facility due on February 11, 2022.

On April 17, 2018, the Company made an additional payment of $15.0 million, including $5.1 million on the Tranche B-3 Facility and $9.9 million on the Tranche B-4 Facility. Borrowings under the Amended and Restated Senior Credit Facility are guaranteed by each of the Company’s wholly-owned domestic subsidiaries (other than certain excluded subsidiaries) and are secured by a lien on substantially all of the assets of the Company and such subsidiaries. Borrowings with respect to the TLA Facility and the Company’s revolving credit facility (collectively, “Pro Rata Facilities”) under the Amended and Restated Credit Agreement bear interest at a rate tied to Acadia’s Consolidated Leverage Ratio (defined as consolidated funded debt net of up to $50.0 million of unrestricted and unencumbered cash to consolidated EBITDA, in each case as defined in the Amended and Restated Credit Agreement). The Applicable Rate (as defined in the Amended and Restated Credit Agreement) for the Pro Rata Facilities was 2.50% for Eurodollar Rate Loans (as defined in the Amended and Restated Credit Agreement) and 1.50 % for Base Rate Loans (as defined in the Amended and Restated Credit Agreement) at June 30, 2019 . Eurodollar Rate Loans with respect to the Pro Rata Facilities bear interest at the Applicable Rate plus the Eurodollar Rate (as defined in the Amended and Restated Credit Agreement) (based upon the LIBOR Rate (as defined in the Amended and Restated Credit Agreement) prior to commencement of the interest rate period).

At June 30, 2019 , the Pro Rata Facilities bore interest at a rate of LIBOR plus 2.50 %. In addition, the Company is required to pay a commitment fee on undrawn amounts under the revolving line of credit. The Amended and Restated Credit Agreement requires the Company and its subsidiaries to comply with customary affirmative, negative and financial covenants, including a fixed charge coverage ratio, consolidated leverage ratio and senior secured leverage ratio.

The fair values of the restricted stock awards were determined based on the closing price of the Company’s common stock on the trading date immediately prior to the grant date. Restricted stock units are granted to employees and are subject to Company performance compared to pre-established targets and Company performance compared to peers. In addition to Company performance, these performance-based restricted stock units are subject to the continuing service of the employee during the two- or three-year period covered by the awards. The performance condition for the restricted stock units is based on the Company’s achievement of annually established targets for diluted earnings per share. Additionally, the number of shares issuable pursuant to restricted stock units granted during 2019 and 2018 are subject to adjustment based on the Company’s three-year annualized total stockholder return relative to a peer group consisting of S&P 1500 companies within the Healthcare Providers & Services 6 digit GICS industry group and selected other companies deemed to be peers. The number of shares issuable at the end of the applicable vesting period of restricted stock units ranges from 0% to 200% of the targeted units based on the Company’s actual performance compared to the targets and, for 2019 and 2018 awards, performance compared to peers. The fair values of restricted stock units were determined based on the closing price of the Company’s common stock on the trading date immediately prior to the grant date for units subject to performance conditions, or at its Monte-Carlo simulation value for units subject to market conditions.

Income Tax Disclosure [Abstract]
Income Taxes	11 . Income Taxes The provision for income taxes for the three months ended June 30, 2019 and 2018 reflects effective tax rates of 19.4% and 15.0%, respectively. The increase in the effective rate for the three months ended June 30, 2019 was primarily attributable to an income tax uncertainty reserve recorded during the three months ended June 30, 2019 related to the deductibility of equity-based compensation. The provision for income taxes for the six months ended June 30, 2019 and 2018 reflects effective tax rates of 19.6% and 6.5%, respectively. The increase in the effective tax rate for the six months ended June 30, 2019 was primarily attributable to an income tax uncertainty recorded during the six months ended June 30, 2019 related to the deductibility of equity-based compensation. The Company recorded a discrete benefit of $10.5 million during the six months ended June 30, 2018 related to a change in the provisional amount recorded at December 31, 2017 in connection with the Tax Cuts and Jobs Act (the “Tax Act”).

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives	12 . Derivatives The Company entered into foreign currency forward contracts during the three and six months ended June 30, 2019 and 2018 in connection with certain transfers of cash between the U.S. and U.K. under the Company’s cash management and foreign currency risk management programs. Foreign currency forward contracts limit the economic risk of changes in the exchange rate between U.S. Dollars (“USD”) and British Pounds (“GBP”) associated with cash transfers. In May 2016, the Company entered into multiple cross currency swap agreements with an aggregate notional amount of $650.0 million to manage foreign currency risk by effectively converting a portion of its fixed-rate USD-denominated senior notes, including the semi-annual interest payments thereunder, to fixed-rate GBP-denominated debt of £449.3 million. During the term of the swap agreements, the Company will receive semi-annual interest payments in USD from the counterparties at fixed interest rates, and the Company will make semi-annual interest payments in GBP to the counterparties at fixed interest rates. The interest payments under the cross-currency swap agreements result in £24.7 million of annual cash flows from the Company’s U.K. business being converted to $35.8 million (at a 1.45 exchange rate). The Company has designated the cross currency swap agreements and forward contracts entered into during 2018 and the six months ended June 30, 2019 as qualifying hedging instruments and is accounting for these as net investment hedges. The fair value of these derivatives at June 30, 2019 and December 31, 2018 of $73.0 million and $60.5 million, respectively, are recorded as derivative instrument assets on the condensed consolidated balance sheets. The gains and losses resulting from fair value adjustments to the cross currency swap agreements are recorded in accumulated other comprehensive loss as the swaps are effective in hedging the designated risk. Cash flows related to the cross currency swap derivatives are included in operating activities in the condensed consolidated statements of cash flows.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	14 . Commitments and Contingencies Professional and General Liability A portion of the Company’s professional liability risks are insured through a wholly-owned insurance subsidiary. The Company is self-insured for professional liability claims up to $3.0 million per claim and has obtained reinsurance coverage from a third party to cover claims in excess of the retention limit. The reinsurance policy has a coverage limit of $75.0 million in the aggregate. The Company’s reinsurance receivables are recognized consistent with the related liabilities and include known claims and any incurred but not reported claims that are covered by current insurance policies in place. Legal Proceedings The Company is, from time to time, subject to various claims, lawsuits, governmental investigations and regulatory actions, including claims for damages for personal injuries, medical malpractice, overpayments, breach of contract, securities law violations, tort and employment related claims. In these actions, plaintiffs request a variety of damages, including, in some instances, punitive and other types of damages that may not be covered by insurance. In addition, healthcare companies are subject to numerous investigations by various governmental agencies. Certain of the Company’s individual facilities have received, and from time to time, other facilities may receive, subpoenas, civil investigative demands, audit requests and other inquiries from, and may be subject to investigation by, federal and state agencies. These investigations can result in repayment obligations, and violations of the False Claims Act can result in substantial monetary penalties and fines, the imposition of a corporate integrity agreement and exclusion from participation in governmental health programs. In addition, the federal False Claims Act permits private parties to bring qui tam, or “whistleblower,” suits against companies that submit false claims for payments to, or improperly retain overpayments from, the government. Some states have adopted similar state whistleblower and false claims provisions. On April 1, 2019, a consolidated complaint was filed against the Company and certain former and current officers in the lawsuit styled St. Clair County Employees’ Retirement System v. Acadia Healthcare Company, Inc., et al. On February 21, 2019, a purported stockholder filed a related derivative action on behalf of the Company against certain former and current officers and directors in the lawsuit styled Davydov v. Joey A. Jacobs, et al. Beard v. Jacobs, et al. Davydov Beard St. Clair County v. Acadia Healthcare During the second quarter of 2019, the Company reached a settlement with the U.S. Attorney’s Office for the Southern District of West Virginia relating to the manner in which seven of our comprehensive treatment centers in West Virginia had historically billed lab claims to the West Virginia Medicaid Program. The Company paid the government $17.0 million during the three months ended June 30, 2019 and entered into a corporate integrity agreement with the Office of Inspector General imposing customary compliance obligations on our subsidiary, CRC Health. In the fall of 2017, the Office of Inspector General issued subpoenas to three of the Company’s facilities requesting certain documents from January 2013 to the date of the subpoenas. The U.S. Attorney’s Office for the Middle District of Florida issued a civil investigative demand to one of the Company’s facilities in December 2017 requesting certain documents from November 2012 to the date of the demand. In April 2019, the Office of Inspector General issued subpoenas relating to six additional facilities requesting certain documents and information from January 2013 to the date of the subpoenas. The government’s investigation of each of these facilities is focused on claims not eligible for payment because of alleged violations of certain regulatory requirements relating to, among other things, medical necessity, admission eligibility, discharge decisions, length of stay and patient care issues. The Company is cooperating with the government’s investigation but is not able to quantify any potential liability in connection with these investigations.

The Company uses Segment EBITDA as an analytical indicator to measure the performance of the Company’s segments and to develop strategic objectives and operating plans for those segments. Segment EBITDA is commonly used as an analytical indicator within the health care industry, and also serves as a measure of leverage capacity and debt service ability. Segment EBITDA should not be considered as a measure of financial performance under GAAP, and the items excluded from Segment EBITDA are significant components in understanding and assessing financial performance. Because Segment EBITDA is not a measurement determined in accordance with GAAP and is thus susceptible to varying calculations, Segment EBITDA, as presented, may not be comparable to other similarly titled measures of other companies.

The Company uses Segment EBITDA as an analytical indicator to measure the performance of the Company’s segments and to develop strategic objectives and operating plans for those segments. Segment EBITDA is commonly used as an analytical indicator within the health care industry, and also serves as a measure of leverage capacity and debt service ability. Segment EBITDA should not be considered as a measure of financial performance under GAAP, and the items excluded from Segment EBITDA are significant components in understanding and assessing financial performance. Because Segment EBITDA is not a measurement determined in accordance with GAAP and is thus susceptible to varying calculations, Segment EBITDA, as presented, may not be comparable to other similarly titled measures of other companies.
