Once the complete provider enrollment packet has been received, the documents will be processed. Processing will take approximately two weeks from the date of receipt. (Remember that mailing time can take as much as five days.)

After processing, a confirmation will be sent to you as notification to begin filing claims electronically. If neither confirmation nor a returned packet is received after two weeks, contact the MassHealth EDI Technology Support Center at 1-800-841-2900.



Once you have received your Submitter ID and Password from MassHealth, please call the ClaimShuttle Support Team and set an appointment for a Mailbox setup and Test Transmission to MassHealth.

Please have 25 test claims ready for testing. Test files should consist of a variety of claims that represent the type of claims you will be submitting once production status is achieved. Test claims will not be processed for payment but will be validated against production files; therefore, they must contain valid patient procedure, diagnosis, and provider information.
