In a post-payment audit, is an original physicians signature still required on the Certificate of Medical Necessity (CMN) or will a faxed CMN be accepted?
When reviewing claims and orders or auditing Certificates of Medical Necessity (CMNs) for DMEPOS, DMERCs may encounter faxed, copied, or electronic orders and CMNs in the supplier files. Generally, DMERCs should accept these documents as fulfilling the requirements for documents. The DMERCs retain the authority to request additional documentation to support the claim. If a DMERC finds indications of potential fraud or misrepresentation of these documents, or the claims submitted, they should refer the matter to the Benefit Integrity Unit for development.
