Recent budget actions approved during the Trump administration included major strategies for reducing federal Medicaid funding and modifying the program. For instance, the “One Big Beautiful Bill Act,” signed into law in 2025, is expected to slash federal Medicaid outlays by over $1 trillion over 10 years, adding requirements such as work documentation and higher out-of-pocket costs. These shifts are poised to impose greater financial responsibility on states and potentially curb federal support, though Medicaid will continue serving tens of millions nationwide.
