At a glance

Michigan uses the federal marketplace at HealthCare.gov, one application for plans, premium tax credits and a Medicaid referral.
Adults up to 138% of the poverty level qualify for Healthy Michigan, which Michigan expanded April 2014.
Most Michiganders who enroll get a subsidy, but the amounts changed when the 2021–2025 enhanced credits expired, run a fresh estimate before assuming a plan is out of reach.
Michigan limits short term plans to 185 days in a year with no renewal, so a short term policy here is a true stopgap rather than a year round alternative.
Every plan is guaranteed issue and covers the ten essential health benefits; the Michigan Department of Insurance and Financial Services licenses the insurers that sell them.

How the marketplace works in Michigan

In Michigan, the marketplace is HealthCare.gov itself. The federal site runs eligibility and enrollment; the Michigan Department of Insurance and Financial Services licenses the insurers and handles complaints about them. A licensed agent can complete the HealthCare.gov application with you at no extra cost.

Whichever insurer you choose, a marketplace plan in Michigan must:

accept every applicant during an enrollment window, whatever their medical history;
cover the full set of essential health benefits with no annual or lifetime dollar caps on them;
set premiums without underwriting, your Michigan rating area, age, tobacco use and household size are the only variables.

Those protections are the whole point of ACA coverage, and the reason it is priced differently from underwritten products. Short term and fixed indemnity products sold in Michigan do not have to follow them; see our short term and fixed indemnity guides for Michigan before treating one as a substitute.

Medicaid in Michigan

Healthy Michigan, Michigan’s Medicaid program (Healthy Michigan Plan), was expanded April 2014. Adults under 65 with household income up to 138% of the federal poverty level generally qualify, including adults without children at home, and enrollment is open all year.

When you apply, one application screens for both. Below the limit you are routed to Healthy Michigan; above it you shop marketplace plans with a tax credit sized to your income. Either way, there is no reason to leave the question unasked.

From 2027, expansion adults in Michigan will face federal work and reporting requirements under the 2025 reconciliation law. Expect notices from Healthy Michigan explaining what to document and when.

What is different about Michigan

Four things about Michigan that change the advice we give:

Michigan limits short term plans to 185 days in a year with no renewal, so a short term policy here is a true stopgap rather than a year round alternative.
The Healthy Michigan Plan covers adults up to 138% of the federal poverty level and is administered through Medicaid health plans you choose after enrollment.

Plan options in Michigan

Marketplace plans in Michigan are sorted into metal tiers. The tiers describe how you and the insurer split costs, not the quality of care or the network:

Bronze, lowest premiums, highest deductibles; a fit if you mainly want protection from a large bill.
Silver, mid-range premiums, and the only tier where cost sharing reductions apply if your income qualifies; often the best value below about 250% of the poverty level.
Gold and Platinum, higher premiums, much lower costs when you use care; worth pricing if you have regular prescriptions or a planned procedure.
Catastrophic, for people under 30 or with a hardship exemption; low premium, very high deductible, and no premium tax credit can be applied.

Networks matter as much as tiers in Michigan: many marketplace plans are HMOs or EPOs with no out of network coverage except emergencies, so check that your doctors and hospital participate before you choose. As an independent brokerage we do not steer you to one insurer; we line up the plans side by side and tell you which tier fits how you actually use care.

How and when to enroll in Michigan

You can enroll at HealthCare.gov online or by phone, or through a licensed agent or certified assister at no cost, the premium is the same either way. Timing is the constraint:

Open Enrollment for Michigan opens November 1 and, on the current HealthCare.gov calendar, closes January 15, with December 15 as the cutoff for a January 1 start. Federal rules on the length of the window have changed and been litigated, so double-check the closing date each fall.
A qualifying life event, a lost job plan, a move to Michigan, marriage, a birth or adoption, opens a 60-day Special Enrollment Period in any month.
No window applies to Healthy Michigan: apply in any month, and coverage can start quickly after approval.

Outside those paths you generally cannot start a marketplace plan midyear, which is why gaps get filled with short term or supplemental products that do not carry the same protections. If that is where you are, compare what is available in your ZIP code and ask us which path makes sense.

What it costs in Michigan

There is no single Michigan premium; there is yours. It comes from:

Income first, for most Michiganders the subsidy, not the sticker price, decides what you pay.
Then age, a 60-year-old pays up to three times a 21-year-old’s premium before subsidies.
Then geography, Michigan’s rating areas price the same plan differently.
Then tier and network, and finally tobacco use.

Subsidies for 2026 and 2027 are calculated under the ACA’s original schedule now that the temporary 2021–2025 enhancements have ended. Get a fresh estimate for your Michigan ZIP code, price Silver against Bronze and Gold, and have us check the arithmetic before you commit.
