NSC Revalidation Process for DMEPOS Suppliers

CMS requires that all DMEPOS suppliers with Medicare billing privileges revalidate with the Medicare program every three years through the National Supplier Clearinghouse. Suppliers will be prompted to revalidate (formerly re-enroll) for billing privileges using the Internet-based Provider Enrollment, Chain and Ownership System (PECOS) system. Don’t wait. Register now to use Internet-Based PECOS in preparation for the receipt of the letter instructing suppliers when revalidation is necessary. Upon receipt of the revalidation letter, suppliers can go online and respond by the requested due date. If the NSC does not receive the completed revalidation packet, the supplier’s billing privileges are subject to normal filing rules including revocation or deactivation. To learn more and register for Internet-based PECOS or to download a hardcopy CMS-855S enrollment application to revalidate your Medicare Billing Privileges, visit the CMS website - www.cms.gov/MedicareProviderSupEnroll. For more information, contact NSC Customer Service during regular operating hours, Monday through Friday, 9 a.m. to 5 p.m. ET at 866-238-9652.

CMS lists the records that need revalidation on their website. CMS sets every supplier's revalidation due-date at the end of a month, and posts the upcoming six months online.
