How should a supplier notify the NSC of their accreditation status?

Accrediting organizations (AO) will report accreditation information to the National Supplier Clearinghouse (NSC). Suppliers may report accrediting information to the NSC by completing section 3B of the CMS 855S enrollment application. Suppliers should also complete sections 3A and 3D if accredited products or services are different from what the NSC has on file for the supplier. Other sections that should be submitted along with section 3B are sections 1B, 7, 11 and 15. Suppliers are encouraged to verify accrediting information with the AOs.
