The CO 31 denial code represents that a claim is denied due to not being medically necessary. When processing a claim, the insurance company assesses the procedure or treatment against specific established medical guidelines and if that procedure as used does not meet the threshold of necessity for the patient’s diagnosis, then this denial code is issued.

Such denial usually is on clinical grounds, in that the procedure is not only determined necessary for conditions at the time but exactly what was going on at the time.
