A Certificate of Medical Necessity (CMN) is a form required to help document the medical necessity and other coverage criteria for selected durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) items. CMNs contain sections A through D. Sections A and C are completed by the supplier and Sections B and D are completed by the physician. A DIF is completed and signed by the supplier. It does not require the cost, a narrative description of equipment or a physician's signature.
