Update - MassHealth Technical Refresh Initiative Phase I: Batch 270/271 Eligibility Transactions - Urgent Message

October 7, 2019

To allow additional time for vendors and providers to prepare for the technical refresh changes to the 270/271 batch eligibility transaction files, MassHealth has extended the implementation date to October 28, 2019. MassHealth will replace its "end of life" HIPAA compliance and translator tool affecting 270/271 batch eligibility transactions. Trading Partners who submit and receive 270/271 batch eligibility transactions are required to evaluate the changes outlined in the MassHealth HIPAA Companion Guides and posted on, 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. Trading Partners who did not test or failed testing are highly likely to receive REJECTED files; which may result in organizations experiencing operational delays in their workflow for checking member eligibility, providing the member's care and potential financial impact downstream with claims submissions.

To assist providers in understanding these changes, MassHealth has developed a quick reference guide of the new compliance requirements. Use this guide to determine the action needed to correct the errors in your submission.
