Important Reminder: Part A Prior Authorization Requests

CGS is receiving prior authorization requests (PARs) through the Part A Provider Contact Center fax number instead of through the appropriate submission methods.

To ensure CGS processes your request timely, please ONLY submit prior authorization requests using the following methods:

PARs submitted on the inappropriate form may receive a rejection. The Fax Request forms can be accessed on the CGS Medicare website and include the appropriate fax number with drop downs to assist in appropriate submission: HOPD Request forms.

Additional checklists and information are available for providers on the CGS Medicare website: Prior Authorization.
