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, 2024, we served approximately 5.7 million members eligible for government-sponsored healthcare programs, located across 21 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 (“RFP”) 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 programs, 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 Florida Procurement—Medicaid. In April 2024, we were notified that the Florida Agency for Health Care Administration issued a notice of invitation to negotiate which did not include Molina Healthcare of Florida as an awardee. We are exercising our right to protest the decision. Michigan Procurement—Medicaid. In April 2024, we announced that the Michigan Department of Health and Human Services intends to award a Comprehensive Health Care Program contract to Molina Healthcare of Michigan. We were awarded the contract in six service regions. The go-live date for the new Medicaid contract is expected to be October 1, 2024. The new contract is expected to have a duration of five years, with three, one-year optional extensions. Texas Procurement—Medicaid. In March 2024, we were notified of the Texas Health and Human Services Commission’s intent to award us a contract for TANF and CHIP (known as the STAR & CHIP programs, and both existing contracts for Molina), expanding our footprint and expecting to grow our market share. The start of operations for the new contract is expected to begin in the third quarter of 2025. Mississippi Procurement—Medicaid. In the first quarter of 2024, Mississippi Division of Medicaid signaled its intention to further extend the existing contracts for at least part of the state fiscal year that will begin on July 1, 2024. We now expect the new four-year contract to commence between September 1, 2024 and July 1, 2025. Virginia Procurement—Medicaid. In the first quarter of 2024, the Virginia Department of Medical Assistance Services (“DMAS”) issued a notice of intent to award which did not include Molina Healthcare of Virginia as an awardee for its Cardinal Care Managed Care (“CCMC”) procurement. We exercised our right to protest that decision. On April 19, 2024, DMAS upheld its notice of intent to award in response to our protest. Molina intends to file a legal action in Virginia District Court over DMAS’s decision not to award Molina a CCMC contract. In addition, DMAS separately notified us that they were exercising the contractual extension option for the period from July 1, 2024 through June 30, 2025. Despite the extension, subject to a 90-day advance notice obligation, DMAS retains its right to terminate the contract for convenience in order to transition members to the new CCMC contracts. California Acquisition—Medicare. Effective January 1, 2024, we closed on our acquisition of 100% of the issued and outstanding capital stock of Brand New Day and Central Health Plan of California (“Bright Health Medicare”), which added approximately 109,000 members. California Procurement—Medicaid. Our new contract with the California Department of Health Care Services commenced on January 1, 2024, which enables us to continue servicing Medi-Cal members in most of our existing counties and expand our footprint in Los Angeles County. Nebraska Procurement—Medicaid. Our new contract with the Nebraska Department of Health and Human Services commenced on January 1, 2024, which added approximately 111,000 members. 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, 2024 are not necessarily indicative of the results for the entire year ending December 31, 2024. 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, 2023. Accordingly, certain disclosures that would substantially duplicate the disclosures contained in our December 31, 2023, audited consolidated financial statements have been omitted. 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.
