Ranks among top 25% of plans nationally to receive a score of 4.5 stars or higher  

BOSTON, MA – October 17, 2022 – Commonwealth Care Alliance® (CCA), a nationally recognized non-profit integrated care system based in Massachusetts, received a rating of 4.5 stars from the Centers for Medicare and Medicaid Services (CMS) as part of the 2023 annual Star Quality Ratings. The rating is for CCA’s Massachusetts Senior Care Options (SCO)* plan, an HMO designed to serve the unique needs of individuals aged 65 and older who are dually eligible for Medicare and Medicaid.

CCA, one of the fastest growing and most unique plans of its kind, has earned national recognition for its proven expertise in complex care coordination and delivery. CCA’s SCO plan serves more than 12,773 individuals with more than 43% of members living with four or more chronic conditions and 57% having a physical or behavioral health disability. More than 70% of SCO members are nursing home certifiable yet can live safely and independently at home with CCA’s care and support.

“Our mission to improve the health and well-being of people with significant needs started here in Massachusetts, and is exemplified by the high-quality, unique care that our plans provide to our members,” said Chris Palmieri, President and CEO of Commonwealth Care Alliance. “I am delighted to celebrate this recognition as it is a fitting tribute to the incredible dedication of our colleagues, whose efforts have removed barriers for our members to help them remain in control of their health and live independently at home.”

CMS’ quality ratings system is designed to help consumers, their families, and caregivers easily compare the quality of the plans available to them and empower them to make the best healthcare decisions. For 2023, CMS rated 507 Medicare Advantage Prescription Drug (MAPD) plans on a scale of 1 to 5 stars. Nationally, the average 2023 Star rating is 4.15 stars. Only 24% of MAPD contracts – including CCA – earned a score of 4.5 stars or higher. Plan ratings are based on care and service quality measures across five categories, including preventive care, managing chronic conditions, member satisfaction, customer service, and pharmacy services.
