Recent federal budget changes enacted under the Trump administration have included major proposals to decrease federal Medicaid support and alter the program structure. For example, the “One Big Beautiful Bill Act” enacted in 2025 is expected to cut over $1 trillion in federal Medicaid funding during the next decade and adds policies like work requirements and higher cost-sharing. Such changes could impact coverage and funding for some recipients by reducing federal support and shifting more costs to states, although Medicaid continues to serve tens of millions across the country.
