Provide your correct PTAN when contacting provider customer service

The Provider Transaction Access Number (PTAN) is your unique Medicare identification number. This number is assigned to providers once their enrollment has been approved. Although the National Provider Identifier (NPI) is used to submit claims to Medicare, the PTAN is required to authenticate a provider’s identity for all transactions relating to billing and enrollment (IVR, SPOT, enrollment requests, provider contact center inquiries, etc.).

For this reason, it is important that you provide the correct PTAN when required to do so in the proper format. For example, all PTANs that have double zeroes as a prefix (00XXXXX) should be provided with those zeroes, followed by the remaining digits. If your PTAN is composed of numbers and letters, be sure to provide the appropriate format and order, without confusing letters and numbers. For example, do not enter the letter “O” in place of the number “0” and vice versa.

When you call our provider contact center, our customer service representatives will require your PTAN to respond to any claim-related inquiries. Please be sure to have the correct PTAN readily available.

If you do not remember your PTAN or are not sure of the proper format, please refer to your enrollment or revalidation letter. If you can’t locate your letter, please refer to our frequently asked questions for additional guidance
