Michigan’s insurance landscape is complex, particularly with its unique No-Fault Act governing auto insurance. When your claim is denied, whether for homeowners, auto, health, or other coverage, Michigan law provides remedies for bad faith conduct and unfair claims practices. The state recognizes both statutory protections under the Unfair Claims Settlement Practices Act and common law bad faith claims, giving policyholders multiple avenues to challenge improper denials.

Understanding Michigan’s claims process and your rights is essential, especially in auto insurance where the No-Fault Act creates specific requirements. This guide explains how to appeal a denial, what constitutes bad faith under Michigan law, and how to recover damages if your insurer acted improperly.

Reasons Insurance Companies Deny Claims

Michigan insurers deny claims citing policy exclusions, coverage limits, alleged misrepresentations or non-disclosure, failure to comply with policy conditions (such as notice requirements), and disputes over causation or valuation. In auto insurance, denials may involve disputes about whether the injury falls within the No-Fault Act’s mandatory coverage framework or questions about the relationship between the accident and claimed injuries. The insurer must have a legitimate basis for any denial and must communicate that basis clearly to the policyholder.

Your Right to Appeal a Denied Claim in Michigan

Step 1 — Internal Appeal

Upon receiving a denial notice, you have 30 days to request an internal appeal. Submit your appeal in writing to your insurance company, clearly stating why you believe the denial was improper. Include any additional evidence: medical reports, repair estimates, policy excerpts, legal arguments, or expert opinions. Michigan law requires insurers to acknowledge your appeal request and provide a written response. The insurer must conduct a reasonable review, considering all submitted information.

Step 2 — External / Independent Review

For health insurance claims, Michigan provides an external review process for denials involving medical necessity or coverage determinations. You may request external review if your internal appeal is also denied. The state’s external review organization will conduct an independent evaluation. For other insurance types, external review is more limited, and you may need to pursue other remedies through the courts or the Department of Insurance.

Step 3 — File a Complaint with the Michigan Department of Insurance and Financial Services

If the insurer denies your internal appeal without proper justification or violates Michigan’s unfair claims practices law, file a complaint with the DIFS. Include your denial letter, internal appeal request, the insurer’s response, and a detailed explanation of your complaint. The Department investigates and may take enforcement action if the insurer violated state law.

Bad Faith Insurance in Michigan

Michigan recognizes bad faith insurance practices under both MCL § 500.2026 (the Unfair Claims Settlement Practices Act) and common law principles. Bad faith occurs when an insurer lacks a reasonable basis for denying a claim, fails to conduct a reasonable investigation, or acts in a manner the insurer knew or should have known was unreasonable. Courts have found bad faith when insurers ignore favorable evidence, apply policy terms inconsistently, or delay claims without justification.

Under Michigan’s unfair claims practices statute, insurers must not misrepresent material facts, fail to acknowledge receipt of communications, fail to conduct a reasonable investigation, or refuse to pay claims without a reasonable basis. Violations expose the insurer to liability for actual damages, penalty interest, and attorney fees. Michigan courts have awarded significant damages in cases where insurers acted recklessly or with intent to harm the policyholder.

If you pursue a bad faith claim successfully, you can recover your actual damages (the denied claim plus costs incurred), penalty interest at a statutory rate, and reasonable attorney fees. In egregious cases where the insurer’s conduct was willful and outrageous, courts may award additional damages beyond the claim amount itself.

Real Situations in Michigan

Detroit, Michigan — Auto Insurance (No-Fault) Denial James suffered a serious car accident and filed a claim under Michigan’s No-Fault Act for medical expenses and wage loss. His insurer denied portions of the claim, arguing that some treatments were not “reasonably necessary” under the Act. The insurer’s medical reviewer reviewed records for only 15 minutes without examining James. James filed a complaint with DIFS and consulted an attorney. The insurer ultimately reversed the denial and paid the full claim plus penalty interest to avoid litigation over the unreasonable investigation.

Grand Rapids, Michigan — Homeowners Insurance Denial Maria’s home sustained wind damage during a severe storm. The insurer denied the claim, attributing the damage to wear and tear rather than the storm. The denial letter contained no inspection findings or evidence of the insurer’s investigation. Maria’s attorney noted the insurer violated MCL § 500.2026 by failing to conduct a reasonable investigation and misrepresenting the basis for denial. The insurer settled for the full claim amount plus $12,000 in additional damages and attorney fees.

Ann Arbor, Michigan — Health Insurance Denial David’s required surgery was denied by his health insurer as “not medically necessary.” His physician’s letters and treatment plan were ignored in the insurer’s brief denial notice. David requested external review, which took 30 days. The external reviewer determined the surgery was medically necessary. The insurer was required to pay for the surgery retroactively. Additionally, David’s complaint to DIFS resulted in the insurer being ordered to revise its claims review procedures.

Common Mistakes Michigan Policyholders Make

Not appealing within 30 days: The internal appeal window is your first critical step. Missing this deadline can complicate later remedies, though it does not eliminate all options.
Not submitting comprehensive supporting evidence: Insurers may claim they lacked information to overturn a denial. Always submit all available medical records, repair estimates, photographs, expert reports, and legal arguments with your appeal.
Failing to document the insurer’s investigation: Request the insurer’s claims file, investigation notes, and the basis for denial in writing. This documentation becomes crucial evidence if you later pursue a bad faith claim.
