Recent federal budgeting under the Trump administration proposed major reductions to federal Medicaid spending and changes to the program. The “One Big Beautiful Bill Act,” enacted in 2025, is set to lower federal Medicaid allocations by more than $1 trillion over the next 10 years and introduces policies such as work requirements and higher cost-sharing, which may curtail benefits and funding for certain recipients. These adjustments are expected to increase the financial role of states and slow the expansion of federal Medicaid support, while the program continues to cover tens of millions of Americans.
