What the data shows for Michigan

Michigan's marketplace insurers denied 16.5% of submitted claims in the CMS data, the 22nd-highest rate of the 31 states with federal marketplace filings. Denial rates this far below the 21% national average usually reflect the state's mix of plan types and risk pool rather than any single carrier — Medicaid managed-care and narrow-network plans route more claims through utilization review.

On the auto side, drivers in Michigan pay an average $1443 a year — more than the $1191 national average — split across $765 liability, $570 collision and $237 comprehensive premiums. That figure has moved down 4% since 2019, tracking the national surge in repair and medical-claim costs.

Because rate regulation, licensing and guaranty-fund coverage are set state by state, an insurer's record in Michigan can differ from its national average — which is why the state view matters for local consumers.
