Your C3 ID number is the same as your MassHealth ID.
Pharmacies should use BIN 009555, PCN MASSPROD, and Group “MassHealth” when filling prescriptions for C3 members.
Welcome to Community Care Cooperative (C3)
C3 is a MassHealth Accountable Care Organization (ACO), created by health centers to better serve their communities. An ACO is a group of doctors and other health care providers who work together to help care for you.
So what does this mean to you?
Your MassHealth Benefits Stay the Same
You Keep Your Health Center Primary Care Provider
Access to the Broadest Network of Hospitals and Specialists
With C3, your MassHealth benefits remain the same. You may see any specialist or hospital that accepts MassHealth without any new paperwork or rules. You keep your health center PCP if you receive care at one of C3’s participating health centers.
For additional information, we invite you to read C3's member brochure.
C3 Member ID card?
As a C3 member, you will have both a C3 Member ID card and a MassHealth Member ID card. C3 members should expect to receive their Member ID card within 15 business days of enrollment.
Bring your C3 ID card and your MassHealth ID card with you when you seek medical, behavioral health, or pharmacy services. Show either card to get the services or medicines you need.
If you did not get a C3 Member ID card, or if your C3 Member ID card is damaged, lost, or stolen, please call us at 866-676-9226 (TTY: 711). In the meantime, use your MassHealth ID card. Your provider can also look you up in the MassHealth system.
You should receive a Welcome Packet from C3
This packet includes a C3 Member Handbook with more information about your benefits and services. Use it to learn how to get the most out of your C3 membership. This Handbook also lists your rights and responsibilities as a member.
Along with this Handbook, the packet will include a Covered Services List. If you have questions about it or need help translating it into your language, please call us at 866-676-9226 (TTY: 711). And, if you need this book in alternate formats, including large print, we can help.
If you did not get a Welcome Packet and/or if you misplace these materials they can always be found on the Member Info page.
