New to helping someone in Michigan?
You do not need a law degree to help someone fight a health insurance denial. Start by gathering three basic documents:
- Insurance card — shows which company administers the plan. Use the name and phone number on the card when you call or file paperwork (it may differ from an employer or clinic name).
- Denial letter or explanation of benefits (EOB)— the notice that says a service was denied, not paid, or needs approval first. Look for appeal instructions and a deadline. On an EOB alone, search for words like "denied," "adverse determination," or "appeal."
- Summary of Benefits and Coverage (SBC) — a plain-language summary of what the plan covers. It helps you tell whether the fight is about medical necessity or whether the benefit exists at all.
Your first tasks: identify what type of plan this is (Marketplace, job-based, Medicaid, Medicare) and write down the appeal deadline from the letter. Missing a deadline is one of the most common reasons people lose appeals they could have won.
Michigan carriers use terms like adverse determination or final adverse determination. You usually appeal first with the insurance company (internal grievance). If that fails, you may request external review through the Michigan Department of Insurance and Financial Services (DIFS) under PRIRA.
For steps that work in every state, read these general guides first, then return here for Michigan rules:
- Denial decoder — what the denial letter is actually saying
- Appeals roadmap — internal appeal, then external review
- Building a strong appeal packet — records and letters to gather
What is different in Michigan?
- HealthCare.gov Marketplace: Michigan uses the federal Marketplace at HealthCare.gov. The insurer on your ID card (Blue Cross, Priority Health, Ambetter, and others) handles PA and appeals.
- Prior authorization (MCL 500.2212e): 7 calendar days standard / 72 hours urgent; missed deadlines can mean PA is deemed granted; electronic PA required; approved PA valid at least 60 days.
- Internal appeals: Often 30 calendar days for preservice denials and 60 days for post-service denials; no timely decision may let you go straight to DIFS.
- DIFS external review (PRIRA): Request within 127 days of final adverse determination (statute: 120 days, MCL 550.1911); IRO recommendation often within ~14 days; expedited review as fast as 72 hours; Director's order binding.
- Medicaid / Healthy Michigan Plan: MCO internal appeal first, then state fair hearing with MOAHR—separate from PRIRA.
Who is in charge of your plan?
The right agency depends on plan type. When in doubt, call member services and ask whether the plan is "fully insured in Michigan" or "self-funded ERISA."
