Minnesota state officials warned the bill would cut $500 million a year in reimbursements for hospital and nursing home coverage.

Of the $16.4 billion annual Medicaid costs for Louisiana, state taxpayers kick in about $3 billion, according to the Legislature. The new law would halt some of the tools Louisiana uses to pay that $3 billion, requiring the state to pour in extra money or let some people go without health insurance.

Covered California, the state's Affordable Care Act health insurance marketplace, estimates that up to 660,000 of the 2 million in the program will be stripped of coverage or drop out.
