Our vision is to transform the health of underserved communities. We work to ensure providers are committed to carrying out that vision in their work and patient care. C3 Members receive primary care services from many of our participating health centers and affiliated providers. We participate in both MassHealth ACO and Medicare ACO REACH contracts. Please select a network below for more information.
Our MassHealth ACO Members also have access to the largest network of specialists and hospitals because we use MassHealth’s PCC Plan Network and the Massachusetts Behavioral Health Partnership (MBHP) as our networks for medical and behavioral health care. If you are participating with the PCC Plan or MBHP, you are already part of C3’s network!
View the list of C3 participating health centers, MassHealth Provider and Dental Directories, and the MBHP Directory.
We hope you are participating in one of the provider networks on which C3 Members rely. If you are not, MassHealth is committed to honoring scheduled appointments, referrals, and prior authorizations during the Continuity of Care (COC) period for the ACO program and to pay for those services. For more information, please refer to this COC bulletin from MassHealth. We appreciate your attention and service to C3 Members during this transition period.
