We’re here for you
Mass General Brigham Health Plan is proud to provide MassHealth insurance coverage to members of Mass General Brigham ACO.
What you need to know about MassHealth eligibility redeterminations
MassHealth needs to renew coverage for all members to make sure they are still eligible and receive the best benefit they qualify for. If you or the head of your household recently received a notice from MassHealth saying that you need to renew your coverage, you must respond by the due date on your renewal notice.
You should also report any changes to your mailing address if you have recently moved. Learn how to report these changes here.

Our goal is to help you see the doctors you need to improve your health. A Mass General Brigham primary care provider will look after your care. You'll also have access to other benefits, support programs, and services.
