Virginia Medicaid operates under Cardinal Care, the unified managed care program DMAS created in October 2023 by merging Medallion 4.0 and Commonwealth Coordinated Care Plus. Roughly 1.7 million Virginians are enrolled, over 90% inside one of five MCOs: Aetna Better Health of Virginia, Anthem HealthKeepers Plus, Sentara Health Plans, UnitedHealthcare Community Plan, and as of July 1, 2025 Humana Healthy Horizons, which absorbed Molina's membership when Molina exited the state. Still verifying former Molina patients under the old plan? That's generating avoidable denials.
Commercial coverage is just as concentrated. Anthem HealthKeepers (Elevance) writes close to half of Virginia's individual and group plans statewide; Sentara Health Plans is strongest in Hampton Roads, vertically integrated with the Sentara Health system; Cigna, Kaiser Permanente, UnitedHealthcare, and CareFirst BlueChoice (Northern Virginia only) cover the rest. Sentara Health, Inova, VCU Health, UVA Health, Carilion Clinic, Bon Secours Mercy Health, and HCA Virginia account for most inpatient volume, but a widening urban-rural split sits underneath: a June 2026 Virginia Joint Commission on Health Care report found 13 of the state's 36 rural hospitals at distant or immediate risk of closure, driven by federal Medicaid cuts and expiring ACA subsidies. Every closure reshuffles referral patterns and out-of-network exposure for the practices left standing.
