Minnesota operates its own state-based marketplace, MNsure, rather than using HealthCare.gov. Residents shop for plans and apply for subsidies directly through the state exchange.
Minnesota expanded Medicaid under the ACA, so adults earning up to 138% of the federal poverty level generally qualify for Medical Assistance, the state's Medicaid program. Minnesota also runs MinnesotaCare, a Basic Health Program that covers residents with incomes a bit above the Medicaid cutoff but still relatively low, offering an additional coverage tier between Medicaid and marketplace plans.
Because Minnesota has this extra MinnesotaCare tier, residents near the lower end of the income scale should check both Medical Assistance and MinnesotaCare eligibility before assuming they need a subsidized MNsure plan, since those programs often carry lower out-of-pocket costs. Insurance regulation in Minnesota falls under the Department of Commerce rather than a separate insurance department, which is worth knowing when looking up complaint or licensing information.
