Medicare basics in Michigan
Medicare is a federal program, so the core rules are the same in Michigan as everywhere else — but the specific plans available, premiums, and carrier networks vary by ZIP code and county.
Most Michigan residents become eligible at 65 through Social Security. See eligibility for full rules.
For the 7-month enrollment window timeline, see Turning 65.
What Michigan residents typically compare
- Medicare Advantage — Many Michigan counties have 20-50+ Advantage plans. Plans, premiums, and extras vary by county.
- Medicare Supplement (Medigap) — Plans are federally standardized but premium pricing and underwriting rules vary by state.
- Part D prescription drug plans — Available statewide but formularies and preferred pharmacies differ by plan.
See Advantage vs. Supplement for the side-by-side framework.
Michigan timing rules
The federal Medigap Open Enrollment window is the same everywhere — 6 months starting the month you turn 65 AND have Part B. During that window, no medical underwriting.
Outside that window, most states (including Michigan unless otherwise noted) allow Medigap carriers to use medical underwriting. Check Michigan's State Health Insurance Assistance Program (SHIP) for current state-specific rules.
