President Trump and other GOP leaders have called for fundamental changes in the structure and financing of Medicaid along with repeal of the Affordable Care Act (ACA). The GOP has proposed transitioning Medicaid from its current structure that provides an entitlement to coverage and provides states guaranteed federal matching dollars with no pre-set limit to a block grant or per capita cap. A block grant would limit all federal Medicaid spending and per capita cap could limit federal funding per enrollee. To understand per capita cap proposals, it is helpful to understand variation in per enrollee spending and per enrollee spending growth across states and enrollment groups. A per capita cap policy could lock in historic variation. A more detailed analysis of per enrollee spending can be found in this brief. This data note uses interactive maps and tables to show variation in per enrollee spending and spending growth by state and eligibility group.
