What is the National Supplier Clearinghouse and what role does it play in Medicare?
The National Supplier Clearinghouse (NSC) is the national entity contracted by the Centers for Medicare & Medicaid Services (CMS) that issues Medicare Durable Medical Equipment, Prosthetics, Orthotics and Supplies (DMEPOS) supplier authorization numbers. The NSC provides DMEPOS supplier applications, verifies application information, and administers file activity. The NSC also maintains a central data repository for information concerning DMEPOS suppliers, periodically re-enrolls active suppliers and uses the data to assist with fraud and abuse research. Medicare suppliers need an DMEPOS supplier number to submit claims to DMEMACs. The NSC may be reached by calling 1-866-238-9652.
