MassHealth HIPAA Testing Process

Providers who wish to submit EDI HIPAA-compliant 837 Professional and Institutional claims transactions directly to MassHealth, using billing software, must successfully complete compliance testing with MassHealth before submitting production claims. Providers who contract with a billing intermediary or claims clearinghouse must ensure that their billing intermediary or claims clearinghouse has completed compliance testing successfully with MassHealth.

If you do not know if your vendor/intermediary is approved to submit EDI claims to MassHealth, or are considering using a vendor for billing purposes, please view the vendor list below, which provides a current status of approved MassHealth vendors and the type of transactions the vendor supports (for example, coordination of benefits claims as well as void and replace transactions).

This list was not created for endorsement purposes, but rather to assist providers in identifying vendors who support HIPAA-compliant claim transactions with MassHealth.
