Michigan residents shop for ACA health coverage through HealthCare.gov, the federal marketplace, since the state has not built its own exchange platform.
Michigan expanded Medicaid under the ACA through a program called the Healthy Michigan Plan, so adults earning up to 138% of the federal poverty level generally qualify for coverage there rather than needing a subsidized marketplace plan.
Michigan's marketplace includes a mix of statewide and regional insurers, and residents in the Upper Peninsula sometimes see fewer plan choices than those in southeastern Michigan around Detroit. Checking network coverage for a preferred health system is worthwhile before choosing a plan, especially for people managing ongoing care with a specific set of doctors.
