How are state costs matched by the federal government?
Although the federal government establishes a framework for all states to follow, each state can administer its own Medicaid program differently. The costs of operating the program are shared between the two, with the federal government matching state spending for eligible beneficiaries based on a formula called the federal medical assistance percentage (FMAP). This calculation is designed so that the federal government pays a larger share of costs in poorer states, such as West Virginia and Mississippi. In 2020, the FMAP ranged from a base level of ** percent up to ** percent.
