Medicaid and the Affordable Care Act
Perhaps the most widely discussed change that the Patient Protection and Affordable Care Act (ACA, P.L. 111-148, as amended) made to Medicaid was expanding eligibility to adults with incomes up to 138 percent of the federal poverty level (FPL). Originally a requirement, the June 2012 Supreme Court ruling in National Federation of Independent Business v. Sebelius effectively made the Medicaid expansion an option, and to date, more than half of states have opted to expand. The ACA also made a number of other significant Medicaid changes, such as preventing states from reducing children’s Medicaid eligibility until FY 2019; setting a uniform standard for children’s eligibility at 138 percent FPL; streamlining eligibility, enrollment, and renewal processes; and updating payments to safety-net hospitals.

March 13, 2015
Premium assistance—the use of Medicaid funds to purchase private market plans—is one way that states may expand coverage to previously ineligible, low-income adults.
