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 persons with disabilities. CCA offers two health plans: Senior Care Options (HMO SNP), for individuals ages 65 and over 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 inter-professional care team in conjunction with CCA’s preferred provider network. For four consecutive years, CCA’s One Care plan earned a top rating from a consumer survey conducted by the Centers for Medicare & Medicaid Services (CMS), and CMS rated CCA’s Senior Care Options 4.5 out of 5 stars for 2021. CCA was named one of the Top Places to Work in Massachusetts by the Boston Globe in 2020.
