CMN in Medical Billing Explained
In medical billing, a Certificate of Medical Necessity (CMN) is often required for durable medical equipment (DME) or certain treatments. The CMN, signed by the healthcare provider, justifies the medical necessity of the service or equipment to ensure it will be covered by the patient’s insurance plan.
For example, a patient’s doctor submits a CMN to the insurance company to authorize the coverage of a wheelchair as a medically necessary item.
