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

AI EXPLANATION: Lumbar facet radiofrequency ablation is an outpatient procedure designed to relieve chronic lower back pain. Under the guidance of real-time imaging, such as X-rays or a CT scan, a doctor carefully places a specialized needle near the small nerves that carry pain signals from the joints in your lower spine. Gentle heat generated by radio waves is then applied to turn off those nerves, helping to interrupt the pain messages sent to the brain.
