Recent federal budget legislation during the Trump administration brought significant proposals to reduce federal Medicaid funding and overhaul the program. Notably, the “One Big Beautiful Bill Act,” passed in 2025, is expected to cut more than $1 trillion from federal Medicaid spending over the next decade and introduce changes, such as work requirements and elevated cost-sharing, that may reduce both coverage and funding for some recipients. These changes are likely to shift more financial responsibility to states and may limit federal Medicaid spending growth, even while the program continues supporting millions of Americans.
