Recent federal budget actions under the Trump administration have put forward substantial efforts to reduce federal support for Medicaid and revise the program’s structure. For instance, the “One Big Beautiful Bill Act,” signed in 2025, is expected to reduce federal Medicaid expenditures by more than $1 trillion over the coming decade and set new policies, such as work requirements and greater cost-sharing, that may impact coverage amounts and funding for several beneficiaries.
