Pain management
About 64490: Cervical or thoracic facet injection, one level
Image-guided injection of a cervical or thoracic facet joint or its supplying nerve at one level for suspected facet-mediated pain.
Code 64490 represents an image-guided injection directed to a cervical or thoracic facet joint, or a nerve supplying that joint, at one spinal level. Pain physicians, anesthesiologists, physiatrists, and interventional radiologists commonly perform it for suspected facet-mediated neck or upper-back pain, including diagnostic blocks used to assess the facet joint as a pain source. The target is a facet joint or its supplying nerve, rather than a spinal nerve root approached through the foramen.
Report one unit for one treated level; use the cervical/thoracic additional-level codes when more levels are treated, and distinguish this region from the lumbar series. Document the spinal region, level, side, target, clinical indication, and image-guided technique. Fluoroscopy or CT guidance is included in the service. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. With modifier 50, bilateral payment is 150%. In a same-session multiple-procedure situation, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.
