Mass General Brigham Health Plan is proud to provide Dual Eligible Special Needs Plans (D-SNPs).
Mass General Brigham Health Plan offers two Dual Eligible Special Needs (D-SNP) plans to support patients with complex needs, providing them more coordinated, team-managed care and extra support services. See all you need to know in the Provider D-SNP overview PPT here.
SCO (Senior Care Options) and One Care plans are available to patients who qualify for both MassHealth (Medicaid) and Medicare in eight Massachusetts counties (Bristol, Dukes, Essex, Middlesex, Nantucket, Norfolk, Plymouth, Suffolk). The plans are designed to serve two specific patient populations:
Each patient is assigned a care manager and an interdisciplinary care team—including the patient’s primary care physician—to collaborate on an integrated plan and facilitate goals. The model ensures patients have a trusted point of contact who is responsible for connecting them with services to address their unique social determinants of health and meet their goals.
All plans include:
Plan information is available to eligible individuals by visiting: MGBAdvantage.org/SCO (for SCO) and MGBAdvantage.org/onecare (for One Care) or by calling 888-816-6000 (TTY: 711) and through select Medicare brokers.

A D-SNP is a health plan for individuals eligible for both Medicare and Medicaid. Mass General Brigham Health Plan (MGBHP) launched two D-SNPs—Senior Care Options (SCO) and One Care—in eight Massachusetts counties (Bristol, Dukes, Essex, Middlesex, Nantucket, Norfolk, Plymouth, Suffolk) starting January 1, 2026. SCO emphasizes aging in place and chronic condition management for older adults, while One Care focuses on younger adults with disabilities.
Every enrollee is assigned a Care Manager and an Interdisciplinary Care Team (ICT). Providers participate in ICT meetings, review Integrated Care Plans (ICP), and collaborate on care transitions. The care model is person-centered, holistic, and aims to support independent living in the community.
Administrative simplification (e.g., only billing MGBHP for services, rather than Medicare and Medicaid separately), improved coordination, enhanced efficiency through integrated care management platform, and potential for higher reimbursement compared to fee-for-service.
Providers interested in enrolling in MGBHP’s SCO and One Care network should submit requests via HealthPlanPEC@mgb.org. Credentialing is required for directory-listed providers; enrollment is required for all. Additionally, providers must maintain current licensure, malpractice insurance, and update CAQH profiles every 90 days and notify MGBHP of roster changes and terminations at least 30 days in advance.
Both plans integrate Medicare and MassHealth benefits, plus supplemental supports. Covered services include inpatient/outpatient care, behavioral health, dental, vision, DME, home health, transportation, personal care, and more.
Member eligibility can be checked through the Provider Portal at Provider.MGBHP.org.
