Implementation of New Provider Authentication Requirements for Medicare Contractor Provider Telephone and Written Inquiries

This CR is intended to address the necessary provider authentication requirements to complete IVR transactions and to complete a call with a Customer Service Representative (CSR). The Disclosure Desk Reference for Provider Contact Centers will be updated in Chapter 3, section 30 and Chapter 6, section 80 to reflect these changes. CMS will require the National Provider Identifier (NPI), Provider Transaction Access Number (PTAN), and the 5-digits of the tax identification number (TIN) of the provider to authenticate a call. CMS will also request the NPI, PTAN, and TIN for written correspondence with exceptions for providers who use letterhead.
