A bipartisan panel of legislators on Tuesday unveiled a plan to lower the cost of no-fault auto insurance to everyday Michiganders. The plan would allow Michigan drivers to choose their medical coverage level: $250,000, $500,000 or the current unlimited level. In addition, it would tie the rates auto insurers reimburse hospitals to 125 percent of the Medicare reimbursement rate. Non-hospital providers would be reimbursed at 100 percent of the Medicare rates.
