by Anne Paddock

Mass General Brigham (formerly known as Partners HealthCare) is a non-profit, tax-exempt healthcare provider with 16 member institutions that include hospitals, medical centers, urgent and emergency care facilities, community health centers, physician and rehabilitation networks, a teaching organization, health insurance plan, and more in the Boston area who changed its name to Mass General Brigham (taking the name of two premier hospitals: Massachusetts General and Brigham and Women’s) in November, 2019.

With 92,000 employees (including 6,500 physicians and 9,100 registered nurses), Mass General Brigham is the largest private employer and healthcare provider in Massachusetts. The Mass General Brigham healthcare network has dozens of related and affiliated tax-exempt organizations and several taxable as a corporation, partnership, or trust (see Schedule R of the Form 990’s).

  • Mass General Brigham Inc and Affiliates Group Return; and

  • Expenses totaled $23 billion with the largest expenses reported to be:  compensation ($11 billion), miscellaneous expenses with no detail ($3 billion), office expenses ($4 billion), and fees for outside services ($2 billion).
