ST. PAUL, Minn. -

Health insurance premium rates through the failed $400 million MNsure website have reached historic levels. Preliminary rate increases were released through healthcare.gov on Thursday afternoon.

Minnesota families and individuals who buy insurance on their own could pan an average increase around 60 percent, the highest average increase of any year since Gov. Dayton and Democrats established MNsure.

Thursday's preliminary rate increases are on top of increases of up to 17 percent and 49 percent in the past two years. In the first two years of MNsure, the average cost of a modest health insurance policy has gone up $2,760 per year in Southeast Minnesota; $4,800 per year for a family of four in the Twin Cities; and even more in other parts of the state.

Over 75 percent of people who buy health insurance on their own do not receive any financial assistance from MNsure.

Earlier this year, Democrats proposed hiking the MNsure Tax by $40 million and raising health care costs by $1 billion by permanently restoring the sick tax.

The preliminary rates remain under review by the Minnesota Department of Commerce to be finalized later this month.
