Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business Overview On February 26, 2024, Apollo Medical Holdings, Inc. rebranded as Astrana Health, Inc (“Astrana”). Unless the context dictates otherwise, references in these notes to the financial statements, the “Company,” “we,” “us,” “our,” and similar words are references to Astrana and its consolidated subsidiaries and affiliated entities, as appropriate, including its consolidated variable interest entities (“VIEs”). Headquartered in Alhambra, California, Astrana is a leading provider-centric, technology-powered, risk-bearing healthcare company. Leveraging its proprietary end-to-end technology solutions, Astrana operates an integrated healthcare delivery platform that enables providers to successfully participate in value-based care arrangements, thus empowering them to deliver accessible, high-quality care to patients in a cost-effective manner. Together with Astrana’s affiliated physician groups and consolidated subsidiaries and VIEs, the Company provides value-based care enablement services and care delivery with its consolidated care partners to serve patients in California, Nevada, and Texas, the majority of whom are covered by private or public insurance provided through Medicare, Medicaid, and health maintenance organizations (“HMOs”), with a small portion of our revenue coming from non-insured patients. The Company provides care coordination services to each major constituent of the healthcare delivery system, including patients, families, primary care physicians, specialists, acute care hospitals, alternative sites of inpatient care, physician groups, and health plans. The Company’s physician network consists of primary care physicians, specialist physicians, physician and specialist extenders, and hospitalists. Segments The Company’s reportable segments changed from one to three in the first quarter of 2023 as a result of certain changes to the information regularly provided to the Company’s chief operating decision maker when reviewing the Company’s performance as well as an effort to provide additional transparency to investors and other financial statement users. The three segments identified by the Company are Care Partners, Care Delivery and Care Enablement, which are described as follows: Care Partners The Care Partners segment is focused on building and managing high-quality and high-performance provider networks by partnering with, empowering, and investing in strong provider partners aligned on a shared vision for coordinated care delivery. By leveraging the Company’s unique care enablement platform and ability to recruit, empower, and incentivize physicians to effectively manage total cost of care, the Company is able to organize partnered providers into successful multi-payer risk-bearing organizations that take on varying levels of risk based on total cost of care across membership in all lines of business, including Medicare fee for service (“FFS”), Medicare Advantage, Medicaid, Commercial, and Exchange. Through the Company’s network of “independent practice associations” (“IPAs”), “accountable care organizations” (“ACOs”), and Restricted Knox-Keene licensed health plan, the Company’s healthcare delivery entities are responsible for coordinating and delivering high-quality care to the Company’s patients and ensuring continuity of care in Astrana’s ecosystem across age, stage of life, or life circumstance. One of the Company’s Accountable Care Organizations (“ACO”) began participating in the Next Generation Accountable Care Organization (“NGACO”) Model of CMS in January 2017. The NGACO Model was a Center for Medicare & Medicaid Services (“CMS”) program that allowed provider groups to assume higher levels of financial risk and potentially achieve a higher reward from participating in this new attribution-based risk-sharing model. With the termination of the NGACO Model on December 31, 2021, the Company’s ACO participated as a Direct Contracting Entity (“DCE”) in the standard track of CMS’s Global and Professional Direct Contracting (“GPDC”) Model for Performance Year 2022 (“PY22”), beginning January 1, 2022. CMS has since redesigned the GPDC Model in response to the current Administration’s health care priorities, including their commitment to advancing health equity, stakeholder feedback, and participant experience, and renamed the GPDC Model to ACO Realizing Equity, Access, and Community Health (“ACO REACH”) Model. The Company began participation in the ACO REACH Model on January 1, 2023. Care Delivery The Company’s Care Delivery segment is a patient-centric, data-driven care delivery organization focused on delivering high-quality and accessible care to all patients. The Company’s care delivery organization includes primary care, multi-specialty care, and ancillary care services. This segment includes the following: •Primary care clinics, including post-acute care services; •Multi-specialty care clinics and medical groups, including hospitalist, intensivist, and physician advisory services, cardiac care and diagnostic testing, and specialized care for women’s health; and •Ancillary service providers, such as urgent care centers, outpatient imaging centers, ambulatory surgery centers, and full-service labs. Care Enablement The Company’s Care Enablement segment is an integrated, end-to-end clinical, operational, financial, and administrative platform, powered by the Company’s proprietary technology suite, that enhances delivery of high-quality, value-based care to patients and leading to superior clinical and financial outcomes. The Company provides solutions to providers, including independent physicians, provider and medical groups, accountable care organizations, and payers, including health plans and other risk-bearing organizations. The Company’s platform meets providers and payers where they are, with a wide spectrum of solutions across the total cost of care risk spectrum, ranging from solutions for fee-for-service entities to full risk-bearing entities, and across patient types, including Medicare, Medicaid, Commercial, and Exchange patients. This segment includes the Company’s wholly owned subsidiaries which operate as management services organizations (“MSOs”), which enter into long-term management and/or administrative services agreements with Independent Practice Associations (“IPAs”), ACOs, or clinics. By leveraging the Company’s care enablement platform, providers and payers can improve their ability to deliver high-quality care to their patients and achieve better patient outcomes. Other Affiliates The Company’s other affiliates are not included as a reportable segment and primarily consist of the real estate operations and other entities that are individually immaterial. The real estate operations are deemed Excluded Assets that are solely for the benefit of Allied Physicians of California, a Professional Medical Corporation d.b.a. Allied Pacific of California IPA (“APC”) and its shareholders. Excluded Assets means (i) assets received from the sale of shares of APC’s Series A Preferred equal to the Series A purchase price, (ii) the assets of APC that are not Healthcare Services Assets (as defined in the Series A Preferred purchase agreement), including APC’s equity interests in Astrana Health, Inc., and any entity that is primarily engaged in the business of owning, leasing, developing, or otherwise operating real estate, (iii) any assets acquired with the proceeds of the sale, assignment, or other disposition of any of the assets described in clauses (i) or (ii), and (iv) any proceeds of the assets described in clauses (i), (ii), and (iii). As such, any income pertaining to Excluded Assets have no impact on the Series A Preferred dividend payable by APC to Astrana Health Medical Corporation (“Astrana Medical”), formerly known as AP-AMH Medical Corporation, and consequently will not affect net income attributable to Astrana. APC and Astrana Medical are consolidated variable interest entities of the Company. See Note 18 – “Variable Interest Entities (VIEs)” to the consolidated financial statements for information on the Company’s entities that qualify as consolidated VIEs. On December 26, 2023, APC completed a restructuring transaction to spin-off its real estate investments, a component of Excluded Assets (“the Spin-Off”). To effect the restructuring, APC contributed its real estate investments to a wholly owned subsidiary in exchange for 100% of the subsidiary’s membership interest units, which membership interests were then distributed to holders of APC’s outstanding common stock as a dividend, with each such stockholder receiving one membership interest unit for each share of outstanding APC common stock held. Dr. Thomas Lam, the Company’s Vice Chairman, is the Chief Executive Officer and Chief Financial Officer and a director and stockholder of APC; Dr. Kenneth Sim, the Company’s Executive Chairman, is Chairman and a director and stockholder of APC; and Dr. Albert Young, the Company’s Chief Administrative Officer, is Senor Executive Vice President and a director and stockholder of APC. The Company leases certain properties that were spun-off and will continue to lease from these properties. After the distribution, the real estate investments became related parties since the chief executive officer of the real estate investments is also a board member of the Company. See Note 15 – “Related-Party Transactions” to the consolidated financial statements for information on related party transactions. The dividend was $190.3 million and recorded at fair value of the investments’ net assets on the date of distribution, December 26, 2023. The fair value of the dividend was measured using Level 3 inputs by applying market data of similar real estate comparables. The gain, representing the difference between the fair value and the carrying value of the net assets, was $5.3 million and is presented within other income in the accompanying consolidated statement of income. As a result of the distribution, the real estate investments are no longer included within the consolidated financial statements after December 26, 2023.
