Effective 9/1/2025, the MassHealth Customer Service phone prompts will be changing. Providers will be required to enter their MassHealth Provider ID (PID) to connect with a Customer Service Agent.
If you are unsure of your MassHealth Provider ID (PID), please visit the Provider Self Service website and perform a Provider Enrollment Status check using your NPI. If you are a MassHealth enrolled provider, this will display your Provider ID and Service Location (PID/SL). Please note that for the current prompts we are only requiring the numerical portion to be entered, the 9-digit PID, and not the letter that corresponds to the service location.
You can access the Provider Enrollment Status check on Mass.gov here:
