NSC Supplier Number

40.4 - NSC Supplier Number (Rev. 1040, Issued: 08-25-06, Effective: 09-11-06, Implementation: 09-11-06) To enable direct billing of DMEPOS, an IHS supplier must enroll with the NSC as a “DME Supplier”, secure a Medicare supplier billing number and comply with the supplier standards specified in 42 CFR §424.57, and submit all DME claims to the appropriate DME MAC based on current DME jurisdiction rules. The NSC shall provide identifiers which identify IHS suppliers and IHS providers to facilitate proper reimbursement by DME MACs. All IHS suppliers that do not have a supplier number for billing a DME MAC should complete a Form CMS-855S and obtain a supplier number from the NSC. There are two ways to obtain a supplier number from the NSC: 1) Facilities may call the NSC to request an application for Form CMS-855S. Once the facility has completed the Form CMS-855S, it shall be submitted to the NSC at the address indicated on the form; or 2) Alternatively, facilities may go to the CMS Web site, http://www.cms.gov/Medicare/Provider-Enrollment-and- Certification/MedicareProviderSupEnroll/index.html and download the Form CMS-855S. The application may be completed and submitted to the NSC. Pharmacies located in IHS providers must apply for and receive an NSC supplier number to bill for prescriptions.
