Michigan Private Health Insurance vs. ACA: Which Is Right for You?

By Martin Elefant · Licensed insurance agent · Updated November 2026 · 5 min read

Most Michiganders think there's one way to buy health insurance on your own: HealthCare.gov. There are two. Here's how they actually differ.

How ACA plans work in Michigan

Marketplace plans are guaranteed-issue — every applicant is accepted regardless of health — and priced on income through the premium tax credit. Enrollment is limited to open enrollment (November 1 – January 15) unless you have a qualifying life event. Medicaid is expanded (Healthy Michigan Plan) in Michigan. In Michigan, the marketplace carriers include Blue Cross Blue Shield of Michigan, Priority Health, Molina, Oscar, and Ambetter. Michigan has no state individual mandate.

How private plans work in Michigan

Private shared-network plans are sold outside the marketplace by carriers that lease access to national PPO networks — in Michigan, that's Cigna, Aetna and PHCS PPO. They're medically underwritten, which means a short health questionnaire, and priced on age and health rather than income. You can enroll any month of the year, coverage starts on the 1st, and the plans are month to month.

Which is right for you?

Two questions decide it. Do you qualify for a subsidy? If yes, the marketplace almost always wins. Are you healthy? If you don't get a subsidy and you are, a private PPO is usually less expensive with a broader network. If you don't get a subsidy and you have a serious condition, the marketplace is still the right answer. Michigan has a deep self-employed and skilled-trades workforce, and Blue Cross Blue Shield of Michigan dominates the marketplace — which is why people who want a different network look at private PPOs.
