For Members
Welcome to Community Care Cooperative (C3)
C3 is an Accountable Care Organization (ACO) serving MassHealth Members across Massachusetts. We also serve Medicare Members in certain areas of both Massachusetts and Louisiana. An ACO is a group of doctors and other health care providers who come together to help care for you. At C3, we work to help your primary care provider stay better informed and involved in your care, both inside and outside the health center or practice. We are creating new and improved programs and systems to get you the right care at the right time. We are focused on providing reliable, convenient, quality care in the community where you live and work.
Your Benefits Stay the Same
With C3, your benefits remain the same. If you are a MassHealth member enrolled in our ACO, or a Medicare member enrolled in our ACO REACH program, you will have the same benefits and receive more. You may see your MassHealth or Medicare providers without any new paperwork or rules.
You Keep Your Health Center Primary Care Provider (PCP)
If you receive care at one of our participating health centers or practices, everything stays the same. You will keep your health center or affiliated practice. Find a PCP who is part of our network.
Access to a Broad Network of Hospitals and Specialists
As a member of C3, you have access to a broad network of hospitals and specialists available to MassHealth and Medicare members. If you are a MassHealth member, you may see any specialist or hospital that accepts MassHealth without any new paperwork or rules. If you are a Medicare member, you can continue seeing any Medicare health care provider you choose. Learn more about providers who work with us, visit: Find a Provider
