Interactive Voice Response (IVR) Authenticate Requirements

Effective June 1, 2025, Noridian's Provider Contact Center (PCC) will be able to answer up to three separate inquiries for the same National Provider Identifier (NPI) and Provider Transaction Access Number (PTAN) combination.

To remain in compliance with self-service and authentication requirements, Noridian will ask that all provider combinations first be authenticated through the Interactive Voice Response (IVR) system. Any inquiry for an NPI or PTAN that is different than the combination already authenticated will be asked to call back and reauthenticate through Noridian's IVR.
