“The federal government and the states jointly finance Medicaid.47 The federal government reimburses states for a portion (i.e., the federal share) of each state’s Medicaid program costs. Because federal Medicaid funding is an open-ended entitlement to states, there is no upper limit or cap on the amount of federal Medicaid funds a state may receive. In FY2018, Medicaid expenditures totaled $616 billion. The federal share totaled $386 billion and the state share was $230 billion.48“
