To get a PTAN number, your health care office must be registered with Medicare. Medicare application forms are available on Medicare’s website.


You’ll need your PTAN to get in touch with Medicare on a variety of topics. This is your authentication number for requests for customer service and Medicare’s interactive voice response system, where you can check the request status and eligibility of beneficiaries.
