The Michigan Catastrophic Claims Association on Wednesday announced its fees would increase from $192 to $220 per vehicle, topping last year’s record for the highest-ever fee.

The MCCA is a statutorily-established nonprofit that all auto insurers pay into for Personal Injury Protection due to the state’s auto no-fault system. The cost is built into premiums Michigan motorists pay. When a crash results in serious injury, a person’s auto insurer will pay for the initial $580,000 in medical costs and the MCCA will reimburse for costs afterward.

The $28 increase comes as the MCCA faces high liabilities and costs, according to a press release from the organization. Among the cost drivers are more people receiving benefits, medical cost inflation, an increase in claims and an increased need to recoup investments due to market volatility.

After the MCCA announced the increase, Gov. Gretchen Whitmer called for the state Department of Insurance and Financial Services to accelerate its plans to review the MCCA’s operations, which were last reviewed in 2015.

“Michiganders deserve to know why they are being forced to shell out hundreds of dollars in additional fees for car insurance, which is why I’m ordering an audit to provide drivers with the transparency they deserve,” Whitmer said in a statement.

The MCCA, a private non-profit, has faced criticism in recent years for a lack of transparency. It is not subject to the Freedom of Information Act.

The new $220 rate, which goes into effect July 1 and remains until June 30, 2020, will be the highest in state history. It topped last year’s high of $192, and prior to that the high water mark was $186 from July 2013 to June 30, 2015.

Of the $220, $177.00 goes toward anticipated new claims and expenses and $43.00 goes to address a deficit on existing claims.

The lowest the fee has ever been was from July 1978 to June 1979, when it was $3.

Michigan is unique among states in that it has unlimited lifetime medical coverage for those involved in auto crashes.

According to an annual report from Insure.com, Michigan has the highest auto insurance in the nation. The average for full coverage for a single, 40-year-old male who commutes 12 miles per day was $2,239 in Michigan, as compared to a $1,365 national average.

Michigan lawmakers have considered various plans to reign in auto insurance costs over the past several years, and this year formed the House Select Committee on Reducing Car Insurance Rates.

Legislative leaders have named auto insurance reforms as a top priority this session.
