The Affordable Care Act (ACA) has significant provisions affecting children, non-elderly adults, and employers. Medicaid/CHIP eligibility is expanded to 133% FPL or less for non-elderly (children, parents, and childless adults) in 2014, with states required to maintain current Medicaid and CHIP eligibility standards for children until 2019. CHIP-eligible children who can't get coverage due to waiting lists can get subsidized coverage in exchange. Medicaid income eligibility is based on modified adjusted gross income (MAGIa) with a 5 percentage point income disregard for non-elderly Medicaid eligibility categories. CHIP income eligibility rules are changed to modified adjusted gross income. States are required to offer premium assistance to Medicaid beneficiaries who are offered employer-sponsored insurance (ESI) if cost-effective for the state. The federal government covers 100% of the cost of Medicaid expansion in all states in 2014-2016, 95% in 2017, 94% in 2018, 93% in 2019, and 90% in 2020 and subsequent years.
