Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business Overview Apollo Medical Holdings, Inc. ("ApolloMed") together with its affiliated physician groups and consolidated entities (collectively, the “Company”) is a leading physician-centric, technology-enabled healthcare management company. Leveraging its proprietary population health management and healthcare delivery platform, ApolloMed operates an integrated, value-based healthcare model, which aims to empower the providers in its network to deliver the highest quality of care to its patients in a cost-effective manner. Headquartered in Alhambra, California, ApolloMed's subsidiaries include management services organizations ("MSOs"), affiliated independent practice associations ("IPAs") and a Next Generation Accountable Care Organization ("NGACO"). Network Medical Management, Inc. ("NMM") and Apollo Medical Management, Inc. ("AMM") are the administrative and managerial services companies for the affiliated physician owned professional corporations that contract with independent physicians to deliver medical services in-office and virtually under the Allied Physicians of California, a Professional Medical Corporation d.b.a. Allied Pacific of California IPA ("APC"), Alpha Care Medical Group, Inc. and Accountable Health Care IPA brands. These affiliates are supported by ApolloMed Hospitalists, a Medical Corporation ("AMH") and Southern California Heart Centers, a Medical Corporation ("SCHC"). The Company's NGACO operates under the APA ACO, Inc. ("APAACO") brand and participates in the Centers for Medicare & Medicaid Services program that allows provider groups to assume higher levels of financial risk and potentially achieve a higher reward from participation in the program's attribution-based risk sharing model. 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, and hospitalists. NMM was formed in 1994 as an MSO for the purposes of providing management services to medical companies and IPAs. The management services primarily include billing, collection, accounting, administration, quality assurance, marketing, compliance, and education. Following a business combination, NMM became a wholly-owned subsidiary of ApolloMed in December 2017. APC was incorporated in 1992, for the purpose of arranging healthcare services as an IPA. APC has contracts with various health maintenance organizations (“HMOs”) and other licensed healthcare service plans as defined in the California Knox-Keene Health Care Service Plan Act of 1975. Each HMO negotiates a fixed amount per member per month (“PMPM”) that is to be paid to APC. In return, APC arranges for the delivery of healthcare services by contracting with physicians or professional medical corporations for primary care and specialty care services. APC assumes the financial risk of the cost of delivering healthcare services in excess of the fixed amounts received. Some of the risk is transferred to the contracted physicians or professional corporations. The risk is also minimized by stop-loss provisions in contracts with HMOs. In July 1999, APC entered into an amended and restated management and administrative services agreement with NMM (the initial management services agreement was entered into in 1997) for an initial fixed term of 30 years. In accordance with relevant accounting guidance, APC is determined to be a variable interest entity (“VIE”) of the Company as NMM is the primary beneficiary with the ability to direct the activities (excluding clinical decisions) that most significantly affect APC’s economic performance through its majority representation on the APC Joint Planning Board; therefore APC is consolidated by NMM. AP-AMH Medical Corporation (“AP-AMH”) was formed in May 2019, as a designated shareholder professional corporation. Dr. Thomas Lam, a shareholder, and the Chief Executive Officer and Chief Financial Officer of APC and Co-Chief Executive Officer of ApolloMed, is the sole shareholder of AP-AMH. ApolloMed makes all the decisions on behalf of AP-AMH and funds and receives all the distributions from its operations. ApolloMed has the rights to receive benefits from the operations of AP-AMH and has the option, but not the obligation, to cover losses. Therefore, AP-AMH is controlled and consolidated by ApolloMed as the primary beneficiary of this VIE. In September 2019, ApolloMed completed the following series of transactions with its affiliates, AP-AMH and APC; 1.ApolloMed loaned AP-AMH $545.0 million pursuant to a 10-year secured loan agreement (the “AP-AMH Loan”). The loan bears interest at a rate of 10% per annum simple interest, is not prepayable (except in certain limited circumstances), requires quarterly payments of interest only in arrears, and is secured by a first priority security interest in all of AP-AMH’s assets, including the shares of APC Series A Preferred Stock purchased by AP-AMH, as described below. To the extent that AP-AMH is unable to make any interest payment when due because it has received dividends on the APC Series A Preferred Stock insufficient to pay in full such interest payment, then the outstanding principal amount of the loan will be increased by the amount of any such accrued but unpaid interest, and any such increased principal amounts will bear interest at the rate of 10.75% per annum simple interest. 2.AP-AMH purchased 1,000,000 shares of APC Series A Preferred Stock for aggregate consideration of $545.0 million in a private placement. Under the terms of the APC Certificate of Determination of Preferences of Series A Preferred Stock (the “Certificate of Determination”), AP-AMH is entitled to receive preferential, cumulative dividends that accrue on a daily basis and that are equal to the sum of (i) APC’s net income from healthcare services (as defined in the Certificate of Determination), plus (ii) any dividends received by APC from certain of APC’s affiliated entities, less (iii) any Retained Amounts (as defined in the Certificate of Determination). 3.APC purchased 15,015,015 shares of ApolloMed’s common stock for total consideration of $300.0 million in private placement. In connection therewith, ApolloMed granted APC certain registration rights with respect to ApolloMed’s common stock that APC purchased, and APC agreed that APC votes in excess of 9.99% of ApolloMed’s then outstanding shares will be voted by proxy given to ApolloMed’s management, and that those proxy holders will cast the excess votes in the same proportion as all other votes cast on any specific proposal coming before ApolloMed’s stockholders. 4.ApolloMed licensed to AP-AMH the right to use certain trade names for certain specified purposes for a fee equal to a percentage of the aggregate gross revenues of AP-AMH. The license fee is payable out of any Series A Preferred Stock dividends received by AP-AMH from APC. 5.Through its subsidiary, NMM, the Company agreed to provide certain administrative services to AP-AMH for a fee equal to a percentage of the aggregate gross revenues of AP-AMH. The administrative fee also is payable out of any APC Series A Preferred Stock dividends received by AP-AMH from APC. As part of the series of transaction, APC and AP-AMH entered into Second Amendment to Series A Preferred Stock Purchase Agreement clarifying the term excluded assets ("Excluded Assets"). Excluded Assets means (i) assets received from the sale of shares of the Series A Preferred equal to the Series A Purchase Price, (ii) the assets of the Company that are not Healthcare Services Assets, including the Company’s equity interests in Universal Care, Inc., Apollo Medical Holdings, 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). APC's ownership in ApolloMed was 32.00% at September 30, 2020 and 32.50% at December 31, 2019. Concourse Diagnostic Surgery Center, LLC (“CDSC”) was formed in March 2010 in the state of California. CDSC is an ambulatory surgery center in City of Industry, California organized by a group of highly qualified physicians, which utilizes some of the most advanced equipment in the eastern part of Los Angeles County and the San Gabriel Valley. The facility is Medicare certified and accredited by the Accreditation Association for Ambulatory Healthcare, Inc. As of September 30, 2020, APC owned 45.01% of CDSC’s capital stock. CDSC is determined to be a VIE and APC is determined to be the primary beneficiary. APC has the ability to direct the activities that most significantly affect CDSC’s economic performance and receives the most economic benefits; therefore CDSC is consolidated by APC. APC-LSMA Designated Shareholder Medical Corporation (“APC-LSMA”) was formed in October 2012 as a designated shareholder professional corporation. Dr. Thomas Lam, a stockholder and the Chief Executive Officer and Chief Financial Officer of APC and Co-Chief Executive Officer of ApolloMed, is a nominee shareholder of APC. APC makes all investment decisions on behalf of APC-LSMA, funds all investments and receives all distributions from the investments. APC has the obligation to absorb losses and right to receive benefits from all investments made by APC-LSMA. APC-LSMA’s sole function is to act as the nominee shareholder for APC in other California medical professional corporations. Therefore, APC-LSMA is controlled and consolidated by APC as the primary beneficiary of this VIE. The only activity of APC-LSMA is to hold the investments in medical corporations, including the IPA lines of business of LaSalle Medical Associates (“LMA”), Pacific Medical Imaging and Oncology Center, Inc. (“PMIOC”), Diagnostic Medical Group (“DMG”) and AHMC International Cancer Center, a Medical Corporation (“ICC”). APC-LSMA also holds a 100% ownership interest in Maverick Medical Group, Inc. (“MMG”), Alpha Care Medical Group, Inc. (“Alpha Care”), Accountable Health Care IPA, a Professional Medical Corporation (“Accountable Health Care”), and AMG, a Professional Medical Corporation (“AMG”). Alpha Care, an IPA acquired by the Company in May 2019, has been operating in California since 1993 as a risk bearing organization engaged in providing professional services under capitation arrangements with its contracted health plans through a provider network consisting of primary care and specialty care physicians. Alpha Care specializes in delivering high-quality healthcare to its enrollees and focuses on Medi-Cal/Medicaid, Commercial, and Medicare and Dual Eligible members in the Riverside and San Bernardino counties of Southern California. Accountable Health Care is a California-based IPA that has served the local community in the greater Los Angeles County area through a network of physicians and healthcare providers for more than 20 years. Accountable Health Care currently has a network of over 300 primary care physicians and 600 specialty care physicians, as well as one community and regional hospital medical center, that provides quality healthcare services to its members of three federally qualified health plans and multiple product lines, including Medi-Cal, Commercial, Medicare and the California Healthy Families program. In August 2019, APC and APC-LSMA acquired the remaining outstanding shares of Accountable Health Care’s capital stock that they did not already own (comprising 75%) for $7.3 million in cash (see Note 3). AMG is a network of family practice clinics operating out of three main locations in Southern California. AMG provides professional and post-acute care services to Medicare, Medi-Cal/Medicaid, and Commercial patients through its network of doctors and nurse practitioners. In September 2019, APC-LSMA purchased 100% of the shares of capital stock of AMG for $1.2 million in cash and $0.4 million of APC common stock (see Note 3). Universal Care Acquisition Partners, LLC (“UCAP”), a 100% owned subsidiary of APC, was formed in June 2014, for the purpose of holding an investment in Universal Care, Inc. (“UCI”). On April 30, 2020, UCAP completed the sale of its 48.9% ownership interest in UCI to Bright Health Company of California, Inc. ("Bright") for approximately $69.2 million in cash proceeds (including $16.5 million as repayment of indebtedness owed to APC), plus non-cash consideration consisting of shares of Bright Health, Inc.'s preferred stock having an estimated fair value of approximately $36.2 million on the date of sale. In addition, pursuant to the terms of the stock purchase agreement, APC has a beneficial interest in the equity method investment sold. The estimated fair value of such interest on April 30, 2020 was $15.7 million (see Note 5). As set forth in the Company’s definitive proxy statement filed with the SEC on July 31, 2019 (the “Proxy Statement”), the 48.9% interest in UCI is included in Excluded Assets that remain solely for the benefit of APC and its shareholders. As such, any proceeds or gain on the sale of APC’s indirect ownership interest in UCI has no impact on the Series A Dividend payable by APC to AP-AMH Medical Corporation as described in the Proxy Statement and consequently the sale did not affect net income attributable to ApolloMed. APAACO, jointly owned by NMM and AMM, began participating in the Next Generation Accountable Care Organization (“NGACO") Model of the Centers for Medicare & Medicaid Services (“CMS”) in January 2017. The NGACO Model is a CMS program that allows 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. AMM, a wholly-owned subsidiary of ApolloMed, manages affiliated medical groups, ApolloMed Hospitalists, a Medical Corporation (“AMH”) and Southern California Heart Centers, a Medical Corporation (“SCHC”). AMH provides hospitalist, intensivist, and physician advisory services. SCHC is a specialty clinic that focuses on cardiac care and diagnostic testing.
