Interactive Voice Response (IVR) Authentication

Providers and third-party representatives are reminded to authenticate the facility or provider they're inquiring about, even when calling to speak with a Noridian Contact Center Customer Service Representative (CSR). Callers must enter authentication information into the phone using the keypad or speaking aloud.

Authentication information entered into the IVR will display for the CSR allowing him/her to be ready to assist the caller with inquiries.    

  • National Provider Identifier (NPI);
  • Provider Transaction Access Number (PTAN); and
  • Last five digits of TIN (Tax Identification Number)

Note: If unable to authenticate via the IVR, ensure the correct line of business has been selected when asking for General Inquiries.

  • Select Part B when submitting claims via CMS-1500 or electronic equivalent

Information obtained through the IVR may also be found in the Noridian Medicare Portal (NMP). View the NMP Advantages Over the IVR article to learn more about the NMP benefits.
