Mass General Brigham ACO was established in April 2023. Since then, it has onboarded more than 140,000 members. An integrated plan was put in place during the transition, ensuring that resources were available to those at risk of losing Medicaid coverage. The ACO has enrolled 70% of ACO membership in a secure electronic portal to guarantee connectivity and effective communication. Using a coordinated care model, the ACO has focused not only on physical health but also mental health outreach. The organization looks to support an approved federal waiver to expand continuous eligibility for certain Medicaid populations, with a focus on health-related social needs and health equity efforts.
