Payment Rules          

All items billed to Medicare require a prescription. A DWO is required before billing. Someone other than the ordering physician may produce the DWO. However, the ordering physician must review the content and sign and date the document. Signature and date stamps are not allowed. Signatures must comply with the CMS signature requirements outlined in PIM


In the event of a claim review:

  • Medicare requires a DWO.
  • Medicare requires that there be sufficient detailed information contained in the beneficiary's medical record to demonstrate that the relevant policy requirements were met.

This article presents a summary of the policy requirements related to the errors identified in a CERT review. The majority of reasons for CERT errors (59%) are completely within the purview of suppliers. Thus, suppliers are encouraged to review their claim submission practices, in order to reduce the high level of CERT errors. Statutory requirements necessary for coverage are not discussed in this article. Please refer to the Parenteral Nutrition LCD and related Policy article for complete information.
