An upcoming provider bulletin, set to be released in the beginning of September 2017, will introduce two new Post Office (P.O.) boxes that must be used for mail correspondence for providers, including non-billing providers who order, refer, and prescribe services. The address changes do not apply to Long Term Services and Supports (LTSS) providers, with the exception of submitting paper claims. The full list of LTSS providers can found in All Provider Bulletin 270, with along with the address for LTSS correspondence. 
The new MassHealth Provider Enrollment and Credentialing P.O. box address is the following:  
Attn: Provider Enrollment and Credentialing 
P.O. Box 121205 
Boston, MA  02112-1205  
The new MassHealth Claims P.O. box address is the following: 
Attn: Claims
P.O. Box 120010 
Boston, MA  02112-0010  
For a limited time, MassHealth will continue to receive and process documentation mailed to the previous P.O. boxes in Canton, MA, but all providers are encouraged to immediately use the new addresses.    
If you have any questions, please contact the MassHealth Customer Service Center at 1-800-841-2900 or e-mail
