Cryoablation of Genicular Nerve

Question:

I'm new to coding pain management procedures. My provider plans to begin performing cryoablation of the genicular nerve under ultrasound guidance. What is the correct way to code this procedure?

Answer:

Great question! The appropriate CPT code for this procedure is 64624 Destruction by neurolytic agent, genicular nerve branches including imaging guidance, when performed. This code encompasses all methods of nerve destruction, including cryoablation, as well as radiofrequency, thermal, chemical, and electric techniques.

To report CPT 64624 correctly, documentation must reflect destruction of all three key genicular nerve branches:

• Superolateral

• Superomedial

• Inferomedial

If the provider does not treat all three branches, you must append modifier 52 to indicate reduced services. Also, while imaging guidance is included in the code, make sure the medical record documents its use to support the procedure.
