Revalidation Due Date Lookup Tool

Published 02/08/2018

The Centers for Medicare & Medicaid Services (CMS) has established due dates by which a provider or supplier's revalidation application must reach the Medicare Administrative Contractor (MAC) in order for them to remain in compliance with Medicare's provider enrollment requirements. The due dates will generally be on the last day of a month (for example, June 30, July 31 or August 31). Please submit your revalidation application to Palmetto GBA by the established due date to avoid a hold on your Medicare payments and possible deactivation of your Medicare billing privileges.

The list is available at and includes all enrolled providers and suppliers. Those due for revalidation will display a revalidation due date, all other providers/suppliers not up for revalidation will display a "TBD" (to be determined) in the due date field. This means that you do not yet have a due date for revalidation. Please do not submit a revalidation application if there is not a listed due date. All unsolicited revalidation applications will be returned without processing. An unsolicited revalidation application is an application submitted from providers or suppliers who are not due to revalidate (i.e., display a TBD on the Revalidation Lookup Tool, a revalidation notice has not been received from their MAC requesting them to revalidate or the application is submitted more than six months in advance of the due date).
