For years in most states, Medicaid eligibility had been limited to disabled adults, seniors needing long-term care and very low-income parents with their children.
Then along came the Affordable Care Act. It was designed to grow health insurance coverage across the board. One of its tenets was to expand Medicaid coverage beyond the extremely poor and disabled to include all adults earning up to 138 percent of federal poverty levels.
But in 2012, the Supreme Court gave states the chance to opt out Medicaid expansion.
