Michigan health insurance appeal rights

How appeals work in Michigan

Michigan gives you a two-step path after a denial. First you appeal to your health plan (the internal appeal). If the plan still says no, you can file a free external appeal with the Michigan Department of Insurance and Financial Services (DIFS) under the Patient’s Right to Independent Review Act (PRIRA). For questions of medical necessity or clinical criteria, DIFS assigns an independent review organization (IRO) — a reviewer outside your insurer — whose recommendation informs the DIFS director’s decision.

External review generally applies when a plan denies care as not medically necessary or as experimental or investigational. (Self-funded employer plans governed by federal ERISA rules follow the federal external review process instead — your denial letter will say which applies.)

Step 1 — your internal appeal

Start by asking your insurer for a full and fair review of its decision, in writing, with your denial notice and supporting records. The denial letter tells you how long you have to file, so check it. After you submit, your insurer must issue its final decision within 30 days for care you haven’t received yet (a pre-service denial) or 60 days for care you’ve already received (a post-service denial).

Step 2 — file an external appeal with DIFS

Once the plan upholds its denial, submit your external appeal to DIFS — online or on the paper form — with a copy of the final denial, your reasons for appealing, and any supporting documentation. The review is free. If you need care urgently, you can request an expedited external appeal, decided within 72 hours; it’s available for pre-service denials, requires a treating physician’s letter verifying the urgency, and must reach DIFS within 10 days of the plan’s final decision.
