Ending your membership may be voluntary or involuntary. You can end your membership at any time by:

  • Making a request in writing to:
    Commonwealth Care Alliance
    Member Services
    30 Winter Street
    Boston, MA 02108
  • Contacting Member Services at 1-866-610-2273 (TTY 711).
    We are available 8 a.m. to 8 p.m., 7 days a week.

    TTY/TDD users can call 1-877-486-2048. 24 hours a day, 7 days a week.

Voluntary disenrollment becomes effective on the first day of the month after Commonwealth Care Alliance receives the written request. You are required to continue to obtain all services through Commonwealth Care Alliance and our contracted network of providers and facilities until your disenrollment becomes effective.

Commonwealth Care Alliance must end your membership in certain situations, such as if you are no longer eligible for MassHealth (Medicaid), if you move out of our service area, or if you become incarcerated (go to prison). We cannot ask you to leave our plan for any reason related to your health.

Call Member Services at 1-866-610-2273 (TTY 711) for help if you have questions or concerns. For detailed information on your rights and responsibilities upon disenrollment, see your Evidence of Coverage (Member Handbook).
