Michigan permits short-term health insurance but caps it hard. Under MCL 500.2213b, the term is 185 days or less (9(a)), and coverage is limited to 185 days out of any 365-day period with the same insurer (9(b)) — a rolling annual cap that can't be stacked. Plans must be nonrenewable. In practical terms, that's roughly six months of short-term coverage per year, one of the shortest windows in the country.
Michigan also differs from most states in how these plans are issued. A short-term plan is issued immediately without medical underwriting (9(d)), but it does not cover pre-existing conditions (9(c)) and is not required to include essential health benefits.
Two Michigan-specific market rules shape what's actually offered: an insurer may not issue short-term coverage if its short-term premiums would exceed 10% of its collective gross written premiums for individual health policies in Michigan (2213b(12)), and insurers must file an annual short-term premium report with the Department of Insurance and Financial Services (DIFS) by March 31.
For context, DIFS Bulletin 2025-22-INS (effective October 1, 2025) reaffirms the 185-day cap and notes that the 2024 federal rule requirements are no longer enforced; the underlying Michigan statute is unchanged. The federal 3-month / 4-month rule is currently not being enforced, but Michigan's 185-day cap is the binding constraint here.
If you're a Michigan resident weighing your choices, here's what's realistically on the table (described as coverage types, not specific products):
As an independent, carrier-neutral brokerage, we don't steer you to any single insurer — and in a state that caps short-term coverage this tightly, we'll tell you honestly when an ACA plan or Medicaid is the better fit.
Michigan uses the federally facilitated marketplace at HealthCare.gov for ACA plans. Enrollment there works on a schedule:
Short-term health insurance is different: you can apply any time of year, but in Michigan coverage is capped at 185 days in any 365-day period with the same insurer, and plans are nonrenewable. If you need coverage beyond about six months, an ACA plan (with a Special Enrollment Period if you qualify) or Medicaid is the realistic route.
We don't quote premiums on this page — prices change and depend on your specific situation — but here are the factors that drive the cost of coverage in Michigan:
For ACA marketplace plans, cost works differently: your premium depends on income (which determines subsidy eligibility), age, county, tobacco use, and the metal level you pick. Because Michigan expanded Medicaid through the Healthy Michigan Plan, some lower-income residents may qualify for that coverage instead.
Short-term health insurance is not major medical coverage and is not minimum essential coverage under the Affordable Care Act. In Michigan these plans are issued without medical underwriting but do not cover pre-existing conditions, and they are not required to cover essential health benefits such as maternity care, prescription drugs, mental health services, or preventive care. They may impose annual or lifetime dollar limits. Short-term coverage does not satisfy any applicable coverage requirements and does not qualify you for ACA premium subsidies.
