Healthcare in Massachusetts

Massachusetts has one of the most advanced healthcare systems in the world, home to globally recognized academic medical centers and a long history of healthcare innovation. Massachusetts General Hospital (MGH) in Boston is consistently ranked as one of the top hospitals in the United States and is affiliated with Harvard Medical School. Other world-renowned Boston institutions include Brigham and Women's Hospital, Boston Children's Hospital, Dana-Farber Cancer Institute, Beth Israel Deaconess Medical Center, and Tufts Medical Center. UMass Memorial Medical Center in Worcester is the state's second-largest academic medical center.

Massachusetts was the first state in the nation to achieve near-universal health coverage, passing the landmark Massachusetts Health Care Reform Act in 2006 — a model that influenced the Affordable Care Act. The state's Medicaid program, MassHealth, covers over 2 million residents, and the state operates Massachusetts Health Connector (mahealthconnector.org) as its ACA marketplace.

The Massachusetts Department of Public Health (DPH) (mass.gov/dph) oversees public health programs and healthcare facility licensing. The Massachusetts Board of Registration in Medicine (mass.gov/bornim) licenses physicians and provides online verification.
