Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	17. Commitments and Contingencies Professional and General Liability A portion of the Company’s professional liability risks are insured through a wholly-owned insurance subsidiary providing coverage for up to $10.0 million per claim through August 31, 2022 and $5.0 million and $10.0 million for certain other claims thereafter. The Company has obtained reinsurance coverage from a third party to cover claims in excess of those retention limits. The reinsurance policy has a coverage limit of $75.0 million or $70.0 million for certain other claims 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., Case No. 3:19-cv-00988, which is pending in the United States District Court for the Middle District of Tennessee. The complaint purports to be brought on behalf of a class consisting of all persons (other than defendants) who purchased securities of the Company between April 30, 2014 and November 15, 2018, and alleges that defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) and Rule 10b-5 promulgated thereunder. On September 30, 2022, the court entered an order certifying a class consisting of all persons who purchased or otherwise acquired the common stock of the Company between April 30, 2014 and November 15, 2018. At this time, the Company is not able to quantify any potential liability in connection with this litigation because the case is in its early stages.

Joey A. Jacobs, et al., Case No. 3:19-cv-00167, which is pending in the United States District Court for the Middle District of Tennessee. The complaint alleges claims for violations of Section 10(b) and 14(a) of the Exchange Act, breach of fiduciary duty, waste of corporate assets, and unjust enrichment. On May 23, 2019, a purported stockholder filed a second related derivative action on behalf of the Company against certain former and current officers and directors in the lawsuit styled Beard v.

The complaint alleges claims for violations of Sections 10(b), 14(a), and 21D of the Exchange Act, breach of fiduciary duty, waste of corporate assets, unjust enrichment, and insider selling.

On February 24, 2021, a purported stockholder filed a fourth derivative action on behalf of the Company against former and current officers and directors in the lawsuit styled Solak v. Jacobs, et al., Case No. 2021-0163, which is pending in the Court of Chancery of the State of Delaware. The complaint alleges claims for breach of fiduciary duty, unjust enrichment, waste of corporate assets, and insider selling. At this time, the Company is not able to quantify any potential liability in connection with this litigation because the cases are in their early stages. In the fall of 2017, the Office of Inspector General (“OIG”) 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 OIG 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.
