As Congress considers ways to cut Medicaid spending to help finance the extension of federal tax cuts, a new KFF analysis finds that imposing a cap on federal spending per Medicaid enrollee—known as a “per capita cap”—could trigger a decrease in federal Medicaid spending over a 10-year period of $532 billion to almost $1 trillion,…
This analysis examines the potential impacts on states, Medicaid enrollees, and providers of implementing a per capita cap on federal Medicaid spending, which is one proposal that has been discussed in Congress. Such a plan could decrease federal Medicaid spending by $532 billion to almost $1 trillion over a 10-year period, depending on how states respond. An estimated 15 million people could lose Medicaid coverage by 2034.
The Republican-led Congress is considering plans to cut Medicaid to help pay for tax cuts, with the House budget resolution targeting $880 billion or more in potential reductions to federal Medicaid spending.
