MassHealth Technical Refresh Initiative Phase 2 Testing

January 21, 2020

On March 30, 2020, MassHealth will complete the transition to the new HIPAA compliance and translator tool. Providers and Trading Partners who submit and receive 276/277, 837I/837P and 835 batch transactions are required to evaluate the changes outlined in the MassHealth HIPAA Companion Guides, modify their systems as appropriate, and test the transaction with MassHealth to ensure that files submitted on or after the implementation date will process correctly. 

MANDATORY testing is required for all submitters and will be conducted between January 27 and March 27, 2020. Trading Partners who fail to test are highly likely to receive REJECTED files, which may result in organizations experiencing operational and potential financial loss.

MassHealth has developed tools and resources that can be accessed on the dedicated Technical Refresh homepage at:

To assist providers the MassHealth EDI department will host weekly Office Hours beginning Thursday, January 16 - March 26, 2020 at 2:00 PM (EST).
