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.)
