Reports & Publications

Massachusetts led the nation in 2006 with a comprehensive health care reform law and the establishment of a new Marketplace: the Massachusetts Health Connector, designed to make affordable health insurance available to more people. In 2019, over 280,000 Massachusetts residents have health insurance through the Health Connector, and our state has the highest rate of health insurance coverage in the nation. National health reform builds upon the successful example set by Massachusetts. As a result, individuals, families, and small businesses who go to the Health Connector can find even more options, enhanced benefits, and savings.

January 2019—This brief is designed to provide data and analysis relative to the breadth of choices offered since the Health Connector’s inception to members purchasing outside the curated plan sets of Commonwealth Care or ConnectorCare. Although subsidized plans represent a larger share of the Health Connector’s membership, there are a limited number of standardized plans serving those members. Through examination of the way in which consumers select a single plan from the dozens available, the Health Connector will continue to refine its approach to plan offerings as well as tailoring decision support tools.
