Michigan external review
Michigan's external review under the Patient's Right to Independent Review Act is unusual in two ways: the state insurance Director personally issues a binding order (not just an IRO letter), and every order is published in a searchable database — a public precedent library for your exact denial. The window is tight at 127 days, so move quickly.
Deadlines and decision timelines
- Your filing window: 127 days from the final internal denial.
- Standard review decided in: IRO recommendation within 14 days of assignment; Director's decision within 7 business days after that
- Expedited review decided in: 72 hours — care needed immediately to protect life, health, or ability to regain maximum function; pre-service denials only, filed within 10 days of the plan's final decision with a physician urgency letter
- Cost to you: None
How to file, step by step
- Exhaust the internal grievance process. Michigan requires your insurer's final internal decision first — and for expedited external review, you must have requested an expedited internal appeal too.
- File the DIFS external review form. Online at difs.state.mi.us (Health Care Appeals — Request for External Review; 25MB attachment limit), or the paper form by email, fax (1-517-284-8838), mail, or courier.
- Attach your evidence. The adverse determination letter, your reasons, and supporting records. Experimental/investigational denials also need the DIFS Treating Provider Certification form.
- IRO reviews, the Director orders. For medical issues an assigned IRO recommends within 14 days; the DIFS Director then issues the binding order within 7 business days. Expedited cases finish within 72 hours.
Who can use it
- State-regulated commercial health coverage.
- Not eligible: non-governmental self-funded (ERISA) plans, Medicare, workers' comp, auto, federal employee programs — Medicaid appeals run separately.
What to know
- 127 days from the final adverse determination — one of the shortest state windows.
- The expedited track has its own 10-day filing window after the plan's final decision.
- Every PRIRA order is published — search past orders for your condition and insurer before writing your appeal.
- The Director's order is the final administrative step; either side can appeal to circuit court within 60 days.

Michigan external review FAQ
How long do I have to file in Michigan?
127 days from your insurer's final internal decision — noticeably shorter than the 4-to-6-month windows in most states. The expedited track is shorter still: 10 days from the final decision.
Does Michigan's external review cost anything?
No. DIFS runs external review as a free process for consumers.
Who actually decides my case?
For medical judgment issues, an Independent Review Organization reviews and recommends within 14 days — but the binding order comes from the DIFS Director within 7 business days after that. Both parties can appeal the order to circuit court within 60 days.
Can I see how similar cases came out?
Yes — Michigan publishes every PRIRA external review order in a searchable database on michigan.gov/difs. Look up your condition, treatment, or insurer to see what arguments won.
What if my employer plan is self-funded?
Non-governmental self-funded (ERISA) plans aren't eligible for Michigan's PRIRA process — those use the federal external review. Your denial letter should say which applies.
