As of January 2026, MassHealth has begun rolling out changes to its applications to include new information fields that will be displayed in the Mass.gov Provider Directory. Long-Term Services and Supports (LTSS) and dental providers are reminded to utilize their respective provider portals, and all other provider types should use MassHealth Provider Self-Service https://masshealth.ehs.state.ma.us/ProviderSelfService/ to request the most recent version of applications.
For questions or concerns, use the contact information below:
LTSS providers: please contact the LTSS Provider Service Center at (844) 368-5184 or support@masshealthltss.com.
All other providers: please contact MassHealth at (800) 841-2900 or provider@masshealthquestions.com.
