Suppliers must be in compliance with the current supplier standards to obtain and/or maintain Medicare billing privileges through the NSC. The supplier standards are published in CFR 42 424.57 (c).
The quality standards are guidelines used by the CMS approved accrediting organizations in which suppliers must comply to attain accreditation.
Suppliers are reminded that the NSC and the accrediting organizations are completely autonomous. Compliance with one entity does not guarantee compliance with the other.
