Interactive Voice Response (IVR) - Self-Service Technology

As required by the CMS, if a provider/supplier calls the Contact Center, speaks with a Customer Service Representative (CSR) and requests information that is available in the Medicare Administrative Contractor's (MAC's) Interactive Voice Response (IVR) or the Noridian Medicare Portal (NMP), the CSR shall inform the caller that the information requested is available via the IVR or in NMP and will direct him/her to these options. Noridian offers both the IVR and NMP as self-service options with extended hours throughout the day and weekend.

To provide an efficient and more streamlined service to providers/suppliers, CMS and Noridian require Medicare suppliers to use the IVR or portal for specific information. These services are only available during the hours the Medicare processing system is available.
