Overview of the DMEPOS Revalidation Process
42 CFR section 424.57(e) requires the National Supplier Clearinghouse (NSC) to revalidate suppliers every three years. The NSC, acting for the Centers for Medicare & Medicaid Services (CMS), is the central entity responsible for maintaining supplier identification and ownership data, as well as other business data. Part of that responsibility requires the NSC to share this information with the Durable Medical Equipment Medicare Administrative Contractors (DME MACs) for provider relations and claims processing.
Therefore, it is imperative the NSC have the most accurate information on file. Further, the revalidation process also allows the NSC to determine if the supplier is in compliance with the supplier standards. Suppliers may revalidate via Internet-based PECOS or by downloading a CMS-855S enrollment application.
The revalidation process includes a site visit, if required. Also, workload and the time spent requesting any additional information required to complete the revalidation play a part in determining the processing time. Be sure to respond to requests for information from the NSC timely to avoid having your supplier number deactivated and having to begin the process again.
The NSC has several tools available to assist suppliers through the revalidation process. These include:
- Numerous FAQs regarding the enrollment process
