How to file an external review in Michigan
Michigan runs its own external review under the Patient's Right to Independent Review Act, administered by the Department of Insurance and Financial Services (DIFS), not the federal HHS process. After you receive your health plan's final internal denial, you have 127 days to request review by submitting DIFS Form FIS 0018 or the online form at Michigan.gov/HealthInsuranceAppeal. Medical-necessity disputes are sent to an independent review organization, while contract or policy questions are decided by the DIFS Director. Standard decisions follow in roughly 14 days for contract issues and 21 days for medical-necessity issues. An expedited review, supported by your treating physician, is completed within 72 hours. The process is free to you, and the decision binds the insurer.
Michigan appeal questions
How do I file an external review in Michigan after my insurance denial?
First exhaust your health plan's internal appeal, then submit a request to the Department of Insurance and Financial Services (DIFS) under the Patient's Right to Independent Review Act. You can file online at Michigan.gov/HealthInsuranceAppeal or by completing DIFS Form FIS 0018 and including your final denial letter. DIFS can also be reached by phone for guidance, with representatives available on weekdays.
What is the deadline to request a DIFS external review in Michigan?
You have 127 days from the date you receive the final adverse determination from your insurer to file your external review request with DIFS. This is longer than the four-month window many states use, so confirm the exact date on your final denial letter. If you miss the 127-day window, DIFS generally cannot accept the case, so file promptly.
Does a Michigan external review cost anything, and is the decision binding?
The DIFS external review process is free to consumers. If your case turns on medical necessity, it goes to an independent review organization; if it turns on policy or contract language, the DIFS Director decides it. A decision in your favor is binding on the insurer, which must then cover the service or treatment.
Can I get an expedited review, and what about self-funded employer plans?
Yes. If waiting for a standard decision could seriously jeopardize your health, your treating physician can support an expedited request, and DIFS completes it within 72 hours. Note that expedited review generally applies to pre-service denials. Many self-funded employer plans fall under federal ERISA rather than Michigan law, so those denials typically follow the federal HHS-administered external review instead of DIFS.
