Medicaid is a public insurance program that provides health coverage to low-income families and individuals, including children, parents, pregnant women, seniors, and people with disabilities. The program, which was created by Congress in 1965 as Title XIX of the Social Security Act, is operated by the states and funded jointly by the federal government and the states.

In Oklahoma, the Medicaid program is known as SoonerCare and is operated primarily by the Oklahoma Health Care Authority. In FY 2018, the Medicaid program served more than 1 million individuals at some point over the course of the year. As of October 2019, SoonerCare’s total monthly enrollment was 787,235 people. Of these, nearly two-thirds (64 percent) were low-income children under the age of 21. The next largest category (20 percent) were Aged, Blind and Disabled individuals, followed by low-income working-age adults (9 percent).

Oklahoma’s total Medicaid spending was $5.25 billion in FY 2018, with the federal government accounting for $3.05 billion of that amount. The federal matching rate (FMAP) for most expenses was 59.9 percent.
