Mass General Brigham ACO currently uses the MassHealth network and providers submit claims to MassHealth (MassHealth is the insurer). As of 4/1 the Mass General Brigham ACO members (formerly Partners Healthcare Choice ACO members) will have their MassHealth coverage through MGBHP and therefore providers need to contract with MGBHP to continue to treat these members.
