About Our Unique Healthcare Organization

Based in Massachusetts, Commonwealth Care Alliance (CCA) is a not-for-profit, community-based healthcare organization dedicated to improving care for individuals who are dually eligible for MassHealth (Medicaid) and Medicare with complex medical, behavioral health and social needs, including those with disabilities. With more than 28,000 members, CCA offers two plans: Senior Care Options (HMO SNP), for individuals ages 65 and older who have Medicare and MassHealth Standard or only MassHealth Standard; and One Care, a Massachusetts demonstration program for dual eligible individuals ages 21 to 64. These comprehensive health plans provide all the services covered under Medicare and MassHealth, and other benefits as determined necessary by an interprofessional care team in conjunction with CCA’s preferred provider network. For two consecutive years, CCA’s One Care plan received a top rating in the Consumer Assessment of Healthcare Providers and Systems (CAHPS) annual survey of Medicare-Medicaid Plans (2016 and 2017), administered by the Centers for Medicare & Medicaid Services.*
