HCPCS 64633

Destruction by neurolytic agent, paravertebral facet joint nerve(s), with imaging guidance (fluoroscopy or CT); cervical or thoracic, single facet joint

AI EXPLANATION: Facet joint radiofrequency ablation is an outpatient procedure designed to relieve chronic neck or upper back pain originating from the spine's facet joints. Using real-time imaging guidance such as fluoroscopy (live X-ray) or a CT scan, a clinician directs a specialized needle to the precise sensory nerves near the targeted joint. Mild electrical heat or a targeted solution is then applied to temporarily disrupt the nerve fibers, preventing them from transmitting pain signals to the brain.
