This term refers to people in states that have chosen not to expand Medicaid who earn too much for traditional Medicaid but not enough to qualify for subsidies on the online health insurance marketplaces.
When the ACA was originally drafted, it was with the intention that all states would expand Medicaid eligibility to 138 percent of the federal poverty level (FPL) – $28,676 for per year for a family of three in 2018. Meanwhile, people between 138 and 400 percent FPL would have access to subsidies for purchasing health insurance on the online marketplaces, thus providing seamless coverage. However, in 2012, the Supreme Court ruled that states had a choice in whether or not to expand eligibility. As of March 2019, 14 states have chosen not to, leaving people who would have been covered by Medicaid expansion without access to health insurance, including some 100,000 in Oklahoma. This group constitutes the ‘coverage crater.’
