This paper quantifies the impacts on coverage and cost of expanding Medicaid to cover more of the low-income uninsured, including adults, at various income levels and with improved participation rates.

The analysis models two primary options to expand Medicaid (250% FPL for children, 100% FPL for adults; 300% FPL for children, 150% for adults) as well as the same options with no change for children.
