Managed Care Organizations (MCO)Most Medicaid and FAMIS enrollees get their care through a Managed Care Organization (MCO). An MCO (also known as a health plan) is an organization with a network of primary care providers (PCPs), specialists, hospitals and other health care providers. A PCP is the doctor you choose to provide and coordinate your or your child’s health care. MCOs that provide health care to Medicaid and FAMIS enrollees include Aetna Better Health of Virginia, Anthem HealthKeepers Plus, Magellan Complete Care of Virginia, OptimaHealth Family Care, UnitedHealthcare Community Plan, and Virginia Premier.
