To protect the privacy of Medicare beneficiaries and providers, CGS authenticates certain elements before releasing beneficiary-specific information including:

  • Provider National Provider Identifier (NPI),
  • Provider Transaction Access Number (PTAN),
  • The last five digits of the provider Tax Identification Number (TIN).
  • Beneficiary’s Medicare Beneficiary Identifier,
  • The first six letters of the beneficiary’s last name,
  • The first letter of the beneficiary’s first name, and
  • The beneficiary’s date of birth.

Beginning May 1, 2023, you must authenticate the above elements on your telephone keypad when using options 1-5. PHI will not be taken verbally by the representative.

Questions about a beneficiary’s Medicare eligibility and claim status can often be answered through the Interactive Voice Response (IVR) system and myCGS. For general information, please use option 9.
