How coverage works in Michigan: Michigan residents enroll through the federal marketplace at HealthCare.gov. Michigan expanded Medicaid, so adults are covered up to 138% of the federal poverty level and marketplace subsidies take over above that — no gap between the two. 7 carriers sell marketplace plans across 83 counties.

Understanding Health Coverage in Michigan
Where Medicaid Ends and Subsidies Begin in Michigan
Michigan expanded Medicaid, which makes the income handoff clean. Adults generally qualify for Michigan Medicaid up to 138% of the federal poverty level — roughly $21,597 for a single adult in 2026, higher for larger households. Above that line, you move to the marketplace and premium tax credits take over. There is no gap between the two programs, so nearly every Michigan resident has some subsidized path to coverage.
The practical consequence: if your income is near that threshold and fluctuates — common for self-employed and hourly workers — you may shift between Medicaid and a subsidized marketplace plan during the year. Report income changes when they happen rather than at tax time; it keeps your coverage continuous and prevents a surprise reconciliation.
Who Sells Coverage in Michigan
For 2026, 7 carriers offer marketplace plans across Michigan's 83 counties, with the typical county having 4 to choose from. The broadest availability comes from Blue Cross Blue Shield of Michigan Mutual Insurance Company, Blue Care Network of Michigan, Priority Health. Full-price premiums for a 40-year-old start around $345 per month before subsidies, with the lowest-cost Silver plan near $385. Most enrollees pay far less once premium tax credits apply.
Carrier availability is decided county by county, not statewide — see the full Michigan plan and premium comparison for the county-level breakdown, metal tiers, and deductibles.
Enrollment Timing in Michigan
Open Enrollment for 2026 coverage runs November 1 through January 15 via HealthCare.gov. Outside that window you need a qualifying life event — losing job-based coverage, moving, marriage, divorce, a new baby, or certain income changes — which opens a 60-day Special Enrollment Period. Miss the 60 days and you generally wait for the next Open Enrollment, so act as soon as the event happens. Michigan Medicaid, by contrast, accepts applications year-round.
Michigan Health Insurance FAQ
How do I get health insurance in Michigan?
Michigan residents enroll through the federal marketplace at HealthCare.gov.

Does Michigan have a Medicaid coverage gap?

How many insurance companies offer marketplace plans in Michigan?
For 2026, 7 carriers offer ACA marketplace plans in Michigan across 83 counties. Availability is local: the typical county has about 4. Full-price premiums for a 40-year-old start near $345 per month before subsidies.
Do I qualify for a subsidy in Michigan?
Premium tax credits are based on your household income relative to the federal poverty level and on the benchmark Silver plan in your rating area, so two Michigan residents with the same income in different counties can receive different credits. If you are self-employed, the calculation uses your net income after business deductions — the single most common place people misestimate and overpay. Run the actual numbers before assuming you earn too much.
Can I be denied coverage in Michigan for a pre-existing condition?
No. Every ACA marketplace plan sold in Michigan must cover pre-existing conditions with no waiting period and no health underwriting, and must include the ten essential health benefits. Premiums vary only by age, ZIP code rating area, household size, and tobacco use.
What if I missed Open Enrollment in Michigan?
Check three things in order: whether a qualifying life event opens a Special Enrollment Period for you, whether you qualify for Michigan Medicaid (which enrolls year-round), and whether a medically underwritten private plan fits if you are healthy and have no other option. There is usually some door open — see our guide on what to do if you missed Open Enrollment.
