Additional Client Identifier FAQs

🔸 Some clients will have both a MassHealth Medicaid ID and an AGE Consumer ID. Others may only have one of the two identifiers.

🔸 When troubleshooting a "Client Not Found" error, check the identifier being used:

  • If it does not begin with "100..." or "13...", that's a 🚩 red flag that an accepted client identifier may not be being used.

🔸 Providers should be directed to the appropriate Payer to obtain the correct client identifier.

🔸 If a Provider is unable to obtain the appropriate identifier from a Payer despite repeated efforts, they should be encouraged to contact the State of Massachusetts (EVVfeedback@mass.gov) and report the challenges they are experiencing.
