The Executive Office of Health and Human Services (EOHHS) virtual gateway (VG) has communicated that multifactor authentication (MFA) was implemented effective May 19, 2024. This message highlights the information you need to log in.
All newly assigned users must sign up for MFA to access the Provider Online Service Center (POSC). You must complete the MFA to access the POSC.
Providers that use system-to-system connectivity (HTTP MIME Multipart or SOAP+WSDL) or Healthcare Transaction Service (HTS) to send and receive HIPAA transactions (270/271, 276/277, 835, 837I, 837P, and 999/TA1) through the XML Gateway will need a separate user ID and password to access these specific XML Gateway services. This will be effective June 28. In preparation for this transition, the EOHHS virtual gateway (VG) has begun converting your existing user ID to a systems ID. Affected users will continue to have access to the legacy login. Once you have made the transition to MFA, you will no longer have access to the legacy login. From that point forward, you will need a separate user ID and password to access the POSC.
If you use the system-to-system connectivity methods and have not been contacted by MassHealth, please contact the EDI team at EDI@mahealth.net.
MassHealth providers should NOT submit forms to the virtual gateway (VG). MassHealth providers receive access to the VG through the MassHealth MMIS Provider Online Service Center (POSC). If you require access to the VG or are having issues accessing the POSC through the VG, contact MassHealth at:
