Michigan Health Insurance in 2027: Rules and Options

Michigan residents buy individual coverage on HealthCare.gov, and open enrollment for 2027 runs November 1, 2026 to January 15, 2027, with special enrollment available after losing other coverage, moving, marrying or having a baby. Michigan has no state premium subsidy or reinsurance program, so financial help comes from the federal premium tax credit based on your projected income. The biggest gap for Michigan tradespeople is continuation: the state has no mini-COBRA law, so anyone leaving a shop with fewer than 20 employees should plan on a Marketplace plan or another option within the 60-day special enrollment window. Michigan also keeps a tight rein on short-term plans, which are capped at 185 days in any 365-day period and cannot be stretched with renewals. Federal changes for 2027 expand access to catastrophic plans for people who do not qualify for tax credits and end the requirement that insurers offer standardized plans on HealthCare.gov.

Private health insurance in Michigan

Most people I help in Michigan end up on a private plan, not a Marketplace plan. Private, medically underwritten health insurance is priced on your age, zip code and health instead of your income, so a strong year never raises your premium and there is no tax credit to pay back in April.

Why people leave the Marketplace

Premiums keep climbing. Michigan Marketplace premiums are rising 14.5% on average for 2027.
The subsidy cliff. Above 400 percent of the poverty level ($63,840 for one person, $132,000 for a family of four) you pay full price.
Surprise tax bills. Underestimate your income and you repay the tax credit in April.
Narrow networks. Many plans are local HMOs or EPOs that need referrals and cover little outside the area.
High out-of-pocket costs. 2027 out-of-pocket maximums reach $12,000 per person and $24,000 per family.
One window a year. Outside open enrollment you need a qualifying life event to enroll or switch.

What a private plan does differently

Start any month. If approved, coverage can begin the first of next month, with no wait for open enrollment.
Networks that travel. Many private plans use national PPO networks, which can give you in-network doctors outside Michigan too. Networks vary by plan.
Can cost less than full-price Marketplace plans for some healthy applicants above the subsidy line.
Accident coverage the Marketplace does not offer. A private plan can be paired with accident coverage, a separate policy. What it includes varies by plan.
Approval is based on health. You answer health questions, and acceptance is not guaranteed.

With a significant health condition, or income low enough for a large tax credit, a Marketplace plan can be the better fit, and I will tell you if it is. Either way you see both side by side.

Private plans are not ACA Marketplace plans. Benefits, exclusions and pre-existing condition rules differ by plan and by state, so review the plan details before you enroll.

Where to enroll

Michigan uses HealthCare.gov. Open enrollment for 2027 coverage runs November 1, 2026 to January 15, 2027. Private, medically underwritten plans are sold outside the exchange by licensed agents and can start the first of any month if you are approved.

Leaving a small employer

Michigan has no state continuation law for small employer plans, so people leaving an employer with fewer than 20 workers generally lose group coverage when the job ends, while federal COBRA still applies at larger employers. Losing employer coverage also opens a 60-day Marketplace special enrollment period.

Short-term health plans

Michigan limits short-term plans to 185 days in any 365-day period, with no renewals or extensions past that, regardless of the federal enforcement pause. Short-term plans are medically underwritten, exclude pre-existing conditions and cap benefits, so they fit only a defined gap.

2027 premium changes

Michigan individual-market premiums are set to rise 14.5% on average for 2027, with small-group plans up about 10%. The full breakdown is on the Michigan 2027 rate page.
