Certificate of medical necessity
In the US a certificate of medical necessity is a document required by Centers for Medicare and Medicaid Services to substantiate in detail the medical necessity of an item of durable medical equipment or a service to a Medicare beneficiary.[1] There are different types of CMN for different requirements, e.g., insulin pumps, home health and private duty nursing services, etc.[2]
A CMN typically requires several dates to be specified, such as:
- The "initial date" of the CMN
- The "revised date" of the CMN
- The "recertification" date (usually for oxygen)
- The date the beneficiary signed it
- The date the supplier signed it and
- The date the physician signed it.[2]
