JACKSON, Miss. (AP) — Mississippi lawmakers are expected to vote this week on a proposal that would expand Medicaid coverage to tens of thousands more people, but it includes a work requirement that might not win federal approval.

The state House and Senate passed separate expansion plans earlier this year. With the four-month legislative session pushing into its final days, negotiators from the two chambers submitted a compromise moments before a Monday night deadline. They declined to answer questions after emerging from a closed-door meeting, but the proposal was filed in legislative clerks’ offices.

The plan would require the new Medicaid recipients to be employed at least 100 hours a month in a job that does not provide private health insurance. Or, they could fit into other categories, such as being a fulltime student or the parent of a child younger than 6.
