Important Information on the Revalidation of Medicare Provider Enrollment

The Centers for Medicare & Medicaid Services (CMS) has reevaluated the revalidation requirement in the Affordable Care Act, and believe it affords the flexibility to extend the revalidation period for another 2 years. This will allow for a smoother process for provider and contractors. Revalidation notices will now be sent through March of 2015. IMPORTANT: This does not affect those providers which have already received a revalidation notice. If you have received a revalidation notice from your contractor, respond to the request by completing the application either through internet-based PECOS or completing the appropriate 855 application form.

The first set of revalidation notices went to providers who are billing, but are not currently in the Provider Enrollment, Chain and Ownership System (PECOS). To identify these providers, contractors searched their local systems and if a Provider Transaction Access Number (PTAN) for a physician was not in PECOS, a revalidation request for that physician was sent. We ask all providers who receive a request for revalidation to respond to that request.

For providers NOT in PECOS – the revalidation letter will be sent to the special payments or primary practice address because we don’t have a correspondence address. For providers in PECOS – the revalidation letter will be sent to the special payments and correspondence addresses simultaneously; if these are the same it will also be mailed to the primary practice address. If you believe you are not in PECOS and have not yet received a revalidation letter, contact your Medicare contractor. Contact information may be found at

Institutional providers (i.e., all providers except physicians, non-physicians practitioners, physician group practices and non-physician practitioner group practices) must submit the application fee with their revalidation. In mid-September, CMS revised the revalidation letter that contractors sent to providers to clarify who must pay the fee.

CMS plans to post a list of providers who were sent requests to revalidate. We will make an announcement via CMS listservs when this information is posted. If you are signed up for your Medicare contractor’s listserv you will get a notice that way. You may also sign up for a national listserv for your provider type by going to:
