Health insurers have directed thousands of enrollees off the MNsure exchange by renewing certain policies only in the "off-exchange" market, a practice that threatens to take a bite out of MNsure's revenue.
The most recent shifts were announced earlier this month, but MNsure highlighted the actions during an interview Monday by saying health insurers are renewing certain policies for about 6,500 people next year only in the non-MNsure market.
The change means enrollees would need to buy from the companies directly or through brokers — and not the exchange — if they want to maintain the plan. The shift could save insurers money, MNsure supporters say, because MNsure withholds 3.5 percent of all premiums sold through the exchange to fund its operations.
But insurers deny a financial motive. Some changes stem from competitive reasons, they say, while others recognize complaints from some consumers that the number of health plan choices can be overwhelming.
"It's something I have my eye on," said Alison O'Toole, the MNsure chief executive. "And it's potentially an issue."
About 6 percent of Minnesotans buy coverage in the individual market, and they decide whether to buy a health plan through MNsure or directly from an insurance company.
Three insurers that sold policies on the exchange in 2014 decided to move some or all of their health plan offerings to the off-exchange market for 2015. The prime example was Golden Valley-based PreferredOne, which had some of the lowest premiums in the country during 2014 but withdrew from MNsure after suffering unsustainable losses.
While the PreferredOne retreat was loudly announced, MNsure officials say they've been watching smaller moves by Eagan-based Blue Cross and Blue Shield of Minnesota and Bloomington-based HealthPartners.
