What is a Certificate of Medical Necessity?
A Certificate of Medical Necessity (CMN) is a form required by Medicare authorizing the use of certain durable medical items and equipment prescribed by a physician. This form is to be completed by your doctor or the doctor’s employee. Your supplier will coordinate with your doctor to see that all the necessary information is submitted to Medicare. A change in prescription and/or a change in your condition requires that an updated certificate be completed and submitted.
