A PTAN is given an end-date when it is deactivated, meaning claims can get submitted prior to the end-date within a year of the service date. A provider's PTAN is deactivated when he or she has not billed the Medicare program for four consecutive quarters. The deactivation process occurs every month. Medicare is mandated by CMS to deactivate PTANs not being used. Providers that are not eligible for a Medicare number must have the beneficiary submit the CMS-1490S form. Requests for a "denial only letter" are no longer accepted. Provider Not Eligible for a Medicare PTAN Unless the reasonable charge locality changes, additional PTANs will not be assigned. Noridian may determine and issue more than one PTAN depending only upon the reasonable charge locality of your practice locations. Multiple PTANs for Different Practice Locations May be Appropriate A PTAN's use should generally be limited to a provider's communication with their MAC. While only the National Provider Identifier (NPI) is submitted on claims, the PTAN is a critical number directly linked to a provider or supplier's NPI. MACs issue an approval/notification letter, including PTAN information, when an enrollment is approved. A PTAN is a Medicare-only number issued to providers by Medicare Administrative Contractors (MACs) upon enrollment to Medicare.
