Will the NSC or its contractor conduct site visits with regard to accreditation?

The National Supplier Clearinghouse (NSC) is responsible for ensuring suppliers are in compliance with the Durable Medical Equipment, Prosthetics, Orthotics and Supplies (DMEPOS) supplier standards. The accrediting organizations, which are appointed by the Centers for Medicare & Medicaid Services (CMS), ensure DMEPOS suppliers meet the quality standards.

When a supplier is accredited, that does not automatically mean the supplier has met the requirements to bill Medicare as a DMEPOS supplier.

Both the NSC and the accrediting organizations will conduct site visits or surveys to determine a supplier's compliance with the set of standards each entity is responsible for enforcing. Therefore, suppliers can expect to receive a site visit or survey from both the NSC and the accrediting organizations to verify compliance with the respective set of standards. The NSC will not conduct site visits to determine compliance with the quality standards.
