Provider Authorization Requirements

Due to the Medicare FFS NPI contingency plan, the NPI will not be a required authentication element for general provider telephone and written inquiries until the date that the Centers for Medicare & Medicaid Services (CMS) requires it to be on all claim transactions. In this contingency environment, the provider transaction access number (PTAN) is your current legacy provider identification number. Your PTAN, which may be referred to as your legacy number by some Medicare Fee-for-Service provider contact centers (PCCs), will be the required authentication element for all inquiries to Interactive Voice Response (IVR) systems, customer service representatives (CSRs), and the written inquiries units.

Medicare FFS will give sufficient notice to providers of the contingency plan end date. Until the date, you will need to provide the following:

For Inquiries to the IVR

• PTAN / Legacy Number, depending upon the contractor

For Inquiries to a CSR and Written Inquiries

• PTAN / Legacy Number, depending upon the contractor
• Provider Name
