Medicaid

Medicaid is a joint federal-state program that provides health coverage to low-income individuals and families. Unlike Medicare, which is primarily age-based, Medicaid is a needs-based program that requires applicants to meet income and asset requirements.

Federal Matching Rates

CategoryFederal Match (FMAP)
Standard Medicaid50-77% (varies by state income)
ACA Expansion adults90% (permanent since 2020)
