Recent federal budget legislation passed during the Trump administration included substantial moves to lower federal Medicaid funding levels and alter the program’s structure. For example, the “One Big Beautiful Bill Act,” enacted in 2025, is forecasted to cut over $1 trillion from federal Medicaid expenditure over the coming decade and introduces measures such as employment requirements and higher participant cost-sharing. These policies could limit funding and coverage for some recipients and are expected to transfer more responsibility to states, restricting the future expansion rate of federal Medicaid assistance as enrollment remains high.
