Based in Boston, Commonwealth Care Alliance® (CCA) is a not-for-profit, integrated care system influencing innovative models of complex care nationwide. Mission-based and person-centered, CCA is singularly focused on sustainable and evidence-based healthcare breakthroughs that fill important gaps in care and improve the health and well-being of people with significant needs. This includes advocating for affordable, high-quality, and cost-effective healthcare policies that lead to healthcare equity for individuals who need it most.

CCA’s unique model of uncommon care® has achieved an unparalleled track record of improved health and quality outcomes and lower costs of care.
