End of POSC PA Submission Functionality for DMEPOS Providers

November 5, 2018

MassHealth, in partnership with its 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 to assist providers in submitting their PAs through the LTSS Provider Portal.

As of December 31, 2018, MassHealth will no longer be accepting PAs submitted through the Provider Online Service Center (POSC), with the exception of members in the Community Case Management (CCM) program. All DMEPOS providers must submit all their PAs through the LTSS 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.
