For example, the federal government would pick up the entire cost for the first two years and 95 percent of the cost for the next three years for newly covered working parents in Alabama, which now covers only those making up to 24 percent of the federal poverty level.
But it would pay just 50 percent of the cost for most of those newly enrolled in California, because California already makes eligible working parents earning up to 106 percent of the poverty level and its Medicaid assistance is set at 50 percent. California would get a more generous reimbursement, about 83 percent, only for parents earning from 106 percent to 133 percent of the federal poverty level.
