Closing Down POSC PA Submission Functionality for Home Health Agencies

August 20, 2018
MassHealth, in partnership with our Third Party Administrator (TPA), introduced the Prior Authorization (PA) functionality to the LTSS Provider Portal for skilled nursing and home health aide visits on February 28, 2018, and for home health therapy services on May 14, 2018.
Since that time, MassHealth and our TPA have engaged with home health 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 1, 2018, MassHealth will be closing down the Provider Online Service Center's (POSC) PA functionality for home health agencies. Home health agencies will no longer be able to submit their MassHealth PAs through the POSC and must use the LTSS Provider Portal. (For continuous skilled nursing, please continue to use the POSC).
The LTSS Provider Portal can be located at
