Health plans sold on Michigan’s insurance exchange could see an average 17.3% increase next year, and if recent history is any guide, state regulators could approve the insurance companies’ rate hike requests without many — if any — changes.

The rate increases would mean a financial hit for taxpayers in general and the 345,000 Michiganders who buy their health insurance on the Healthcare.gov exchange, created under the Affordable Care Act, also known as Obamacare.

. . .

A sampling of the 2017 proposed rate increases:

Blue Care Network of Michigan is seeking an average 14.8% rate increase for its plans.

Blue Cross Blue Shield wants an 18.7% increase.

Priority Health has asked for a 13.9% rate hike.

The biggest rate request is from Humana — a 39.2% rise.
