Neurology & Pain Management Coding Alert

Question: What is the correct CPT^® code for ganglion impar neurolysis using Phenol?

Virginia Subscriber

Answer: You should report 64999 (Unlisted procedure, nervous system) for any type of ganglion impar procedure.

Remember: When you select an unlisted code to describe a procedure or service, always submit the claim with supporting documentation (such as a procedure report) to provide an adequate description of the nature, extent, and need for the procedure. Documentation of the time, effort, and equipment necessary to provide the service should also be included. Base your charge on a comparable procedure and explain your logic to the payer. Some practitioners compare the ganglion impar injection of local anesthetic to 64450 (Injection, anesthetic agent; other peripheral nerve or branch) and the destruction procedure using an injection of phenol to 64640 (Destruction by neurolytic agent; other peripheral nerve or branch).
