Answer: You should review the "Destruction by Neurolytic Agent" category in the CPT and look at code 64640 (Destruction by neurolytic agent; other peripheral nerve or branch). This CPT category for nerve destruction includes several techniques that meet the definition of a neurolytic agent, including chemical, thermal, electrical or radiofrequency. Phenol, ethyl alcohol and hypertonic saline are examples of chemical neurolytic agents that physicians have used since the 1920s.
