The BCBSMA payer ID is 00320 (confirmed by MCM South, 10/1/26). Filing limits come from your contract and BCBSMA's Provider Central.
Private payer: credentialing
Many behavioral health clinicians (child psychiatrists, clinical psychologists, LICSWs, LMFTs, LMHCs and LADCs) share one BCBSMA application. New solo practices and groups also complete the Behavioral Health Professional Practice Application (BCBSMA contracting applications).
Behavioral health authorization
Use the line above or the authorization quick lookup. Children's behavioral health services (such as in-home therapy) carry specific modifier and authorization rules, so ask BCBSMA before billing them.
Medicaid and state law
MassHealth is a separate program. Massachusetts insurance rules come from the Division of Insurance.
