Some Obamacare customers in Minnesota will pay less for health insurance coverage in 2018, according to state rate filings published Monday.

The final rates, agreed to by the state and by insurers, range from a 3 percent increase to a 38 percent decrease. Mike Rothman, the state’s Department of Commerce Commissioner, credited the decrease with a $549 million reinsurance program paid for by the state that will help cover costs during the next two years. The program helps pay for the medical costs of sicker customers so that the costs for others do not rise.
