Commonwealth Care Alliance (CCA) is a uniquely special healthcare organization serving some of the most medically and socioeconomically challenged individuals in the Commonwealth of Massachusetts. CCA traces its roots to the 1980s as a multi-disciplinary primary care practice that has come to be regarded as a national model for disability-competent healthcare. Guided by our mission of providing the best possible care, tailored individually to the members we serve throughout Massachusetts – elders and people across the age spectrum with special healthcare needs, CCA serves close to 20,000 beneficiaries dually eligible for Medicare and Medicaid through two health plan options, Senior Care Options and One Care.
