What 64490 covers
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.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
