Pain management
About 64625: Sacroiliac joint nerve radiofrequency ablation
Reports image-guided radiofrequency ablation of nerves supplying the sacroiliac joint to treat pain attributed to that joint’s innervation.
This procedure uses radiofrequency energy to create lesions in nerves that carry pain signals from the sacroiliac joint. Pain medicine physicians, anesthesiologists, and other clinicians who perform image-guided interventions may use it for persistent SI-joint-related pain after evaluation, often including diagnostic nerve blocks. Fluoroscopy or CT guidance is part of the service; the code covers placement of needles at multiple target nerves, including sacral lateral branches.
Report the service for ablation of nerves innervating the SI joint, not for an SI-joint injection or ablation of lumbar facet nerves. The procedure note should identify the treated side and targets, describe the ablation and imaging guidance, and support the relationship of the treated nerves to the patient’s SI-joint pain. Related postoperative visits are included in the 10-day global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 reports a bilateral procedure and is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
