Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Organization and Operations Molina Healthcare, Inc. provides managed healthcare services under the Medicaid and Medicare programs, and through the state insurance marketplaces (the “Marketplace”). We currently have four reportable segments consisting of: 1) Medicaid; 2) Medicare; 3) Marketplace; and 4) Other. Our reportable segments are consistent with how we currently manage the business and view the markets we serve. As of March 31, 2023, we served approximately 5.3 million members eligible for government-sponsored healthcare programs, located across 19 states. Our state Medicaid contracts typically have terms of three to five years, contain renewal options exercisable by the state Medicaid agency, and allow either the state or the health plan to terminate the contract with or without cause. Such contracts are subject to risk of loss in states that issue requests for proposal (“RFPs”) open to competitive bidding by other health plans. If one of our health plans is not a successful responsive bidder to a state RFP, its contract may not be renewed. In addition to contract renewal, our state Medicaid contracts may be periodically amended to include or exclude certain health benefits (such as pharmacy services, behavioral health services, or long-term care services); populations such as the aged, blind or disabled (“ABD”); and regions or service areas. In Medicare, we enter into Medicare Advantage-Part D contracts with the Centers for Medicare and Medicaid Services (“CMS”) annually, and for dual-eligible plans, we enter into contracts with CMS, in partnership with each state’s department of health and human services. Such contracts typically have terms of one to three years. In Marketplace, we enter into contracts with CMS, which end on December 31 of each year, and must be renewed annually. Recent Developments Indiana Procurement—Medicaid. In March 2023, we announced that the Indiana Department of Administration has recommended that contract negotiations begin with our Indiana health plan. Under the proposed contract with the Indiana Family and Social Services Administration (“FSSA”), we are expected to provide risk-based managed care long term services and supports as part of the Indiana Pathways for Aging LTSS program pursuant to the request for proposal issued by FSSA in February 2022. The new contract is expected to have an initial four-year term, with the potential for two one-year renewal terms. Consolidation and Interim Financial Information The consolidated financial statements include the accounts of Molina Healthcare, Inc., and its subsidiaries. In the opinion of management, these financial statements reflect all normal recurring adjustments, which are considered necessary for a fair presentation of the results as of the dates and for the interim periods presented. All significant intercompany balances and transactions have been eliminated. The consolidated results of operations for the three months ended March 31, 2023 are not necessarily indicative of the results for the entire year ending December 31, 2023. The unaudited consolidated interim financial statements have been prepared under the assumption that users of the interim financial data have either read or have access to our audited consolidated financial statements for the fiscal year ended December 31, 2022. Accordingly, certain disclosures that would substantially duplicate the disclosures contained in our December 31, 2022, audited consolidated financial statements have been omitted. These unaudited consolidated interim financial statements should be read in conjunction with our audited consolidated financial statements for the fiscal year ended December 31, 2022. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities. Estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
