How it works here
ACA Marketplace plans, explained for Massachusetts.
Massachusetts residents buy ACA Marketplace plans through Massachusetts Health Connector. These are comprehensive plans that cover the ten essential health benefits, cannot deny you for a pre-existing condition, and are the only plans eligible for income-based premium tax credits.
Because Massachusetts runs a state-based marketplace, you enroll at Massachusetts Health Connector. Plans and prices are set at the county level across Massachusetts's 14 counties, so two neighbors in different counties can see different options.
Massachusetts expanded Medicaid, so if your income is low you may qualify for Medicaid instead of a subsidized plan — the Marketplace will tell you when you apply.
The Massachusetts Health Connector is the state-based marketplace and sits within a long-standing state coverage framework that predates the ACA.
Massachusetts has one of the lowest uninsured rates in the country; ConnectorCare and related programs can further reduce costs for eligible residents.
Plan shopping still varies across the state's 14 counties, including differences between Greater Boston and western Massachusetts.
