Reminder for Providers - Member Social Security Number (SSN) Will Not Appear in Eligibility Response Beginning 12/16/19

November 18, 2019

On December 16, 2019 MassHealth will no longer return the member social security number (SSN) in the Health Care Benefit Response (271) unless the correct SSN is submitted on the Health Care Benefit Inquiry (270) request.

MassHealth requires a valid Member ID (MID) or member demographic data (e.g. first name, last name, DOB, gender) instead of an SSN when checking eligibility. Please ensure that the member's first and last name are spelled correctly, or the inquiry may not result in a response. Please take note of this change and adjust your systems and processes accordingly.

If you have any questions, please contact the MassHealth EDI team at 1-800-841-2900 or
