The top-selling insurer on the state's MNsure exchange has pulled out of the online marketplace just two months before this year's open enrollment period begins.
Golden Valley-based PreferredOne had set the lowest premium prices in the nation last year and signed up nearly 6 in 10 consumers who shopped on the MNsure exchange.
But the insurer's CEO, Marcus Merz, said this week in a letter to the exchange's leaders that "continuing to provide this coverage through MNsure is not sustainable."
The move could portend higher health care premiums in the year ahead and is the latest setback for an exchange that suffered persistent technical problems in its debut year.
"That's a huge blow to MNsure," said Allan Baumgarten, an independent Twin Cities health care analyst.
Baumgarten said PreferredOne appeared to make a calculated gamble that its low premium prices would bring in enough business to enable it to cover an influx of new enrollees, even if they turned out to be sicker.
That strategy helped PreferredOne, the smallest of the five major carriers in the Twin Cities, to grab significant market share from its bigger competitors. But Baumgarten said PreferredOne has also been picking up a lot of business outside the exchange.
"That suggests that between their in-house sales force and relationship with agents and brokers, they think they have a pretty effective selling machine there," Baumgarten said. "Maybe something more effective than MNsure, which by all accounts is not operationally where it needs to be."
