Closing Down POSC PA Submission Functionality for DMEPOS Providers

September 4, 2018

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

Since that time, MassHealth and our 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.

As of October 15, 2018, MassHealth will be closing down the Provider Online Service Center's (POSC) PA functionality for DMEPOS providers, who 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.

Only Pharmacies with a DME specialty are included in this change.
