                    TRADING PARTNER TESTING ENVIRONMENT

                    Active MassHealth trading partners may utilize the MassHealth Trading Partner Testing (TP) environment to test HIPAA transactions supported by MassHealth prior to the provider’s adoption of a specific transaction, or MassHealth’s implementation of any applicable state/federal mandates and agency initiatives.

                    The following transactions are available to test within this environment: 270/271, 276/277, 837P, 837I. Providers may also utilize the Direct Data Entry (DDE) panels to test corresponding claims and eligibility inquiries.

                    If you have any questions about the use of this test environment or test submissions, please contact MassHealth Customer Services at 1-800-841-2900 or via email at EDI@mahealth.net
