Provider Transaction Access Number (PTAN) A PTAN is a Medicare-only number issued to providers by MACs upon enrollment to Medicare. When a MAC approves enrollment and issues an approval letter, the letter will contain the PTAN assigned to the provider.
There are a few ways in which you may be able to locate your PTAN. This number is assigned to each provider and group when they enroll with Medicare. Please check internally with your credentialing area. You may also locate the PTAN in the National Plan and Provider Enumeration System (NPPES). This number is typically listed at the bottom of the National Provider Identifier (NPI) detail screen when doing an NPI search. You may also request it in writing through the Medicare Provider Enrollment (PE) Department.
