Provider Enrollment


Palmetto GBA is the Railroad Retirement Board Specialty Medicare Administrative Contactor (RRB SMAC). We process Part B fee-for-service claims for Railroad Medicare beneficiaries nationwide.

If you are a Part B Medicare provider, you are eligible to provide care to Railroad Medicare patients, but you will need to request and receive a Railroad Medicare Provider Transaction Access Number (PTAN) before we can process your claims. You need this PTAN because we are a different jurisdiction from your local MAC.

No Enrollment Forms Needed
There are no CMS-855 Enrollment forms required for Railroad Medicare. To verify if you have a Railroad Medicare PTAN number and then to request a new PTAN if you don’t have one, you will simply use our online Railroad Medicare PTAN Lookup and Request Tool. 

Before using the PTAN Tool, please review the following resource: Using Railroad Medicare's Online PTAN Lookup and Request Tool.

See our Verify Enrollment page and Enroll a Provider page for more information.

Once you receive your Railroad Medicare PTAN, it is important to keep the information in your enrollment record current. See our Update an Enrollment Record page for directions on reporting enrollment changes to Railroad Medicare.
