Date Change: End of POSC PA Submission Functionality for DMEPOS Providers Will Occur January 31, 2019, Rather Than December 31,2018

December 26, 2018

MassHealth, in partnership with our Third Party Administrator (TPA), introduced Prior Authorization (PA) functionality to the LTSS Provider Portal for Durable Medical Equipment, Prosthetics, Orthotics and Supplies (DMEPOS) and Oxygen and Respiratory Therapy Equipment in June, 2018.

Since that time, MassHealth and its TPA have engaged with DMEPOS providers through in-person and online trainings, as well as individual outreach in order to assist providers in submitting their PAs through the LTSS Provider Portal. The DME Provider Portal Training Guide can be found at The date for transition from POSC to the LTSS Provider Portal has changed from December 31, 2018 to January 31, 2019.

As of January 31, 2019 at 5PM, MassHealth will no longer be accepting PAs submitted through the Provider Online Service Center (POSC) for DMEPOS providers, with the exception of members in the Community Case Management (CCM) program. This means that beginning February 1, 2019, all DMEPOS providers will no longer be able to submit their MassHealth PAs through the POSC and must use the LTSS Provider Portal. Providers submitting PAs for CCM members must continue to use the POSC.

For pharmacy providers, only those with a DME or Oxygen specialty are included in this change.
