About 64510: Stellate ganglion anesthetic injection
Reports an anesthetic injection at the cervical sympathetic stellate ganglion, commonly used to evaluate or treat sympathetically maintained pain affecting the upper extremity.
A stellate ganglion block places anesthetic near the cervical sympathetic ganglion in the neck. Pain-management physicians and anesthesiologists commonly perform it for selected cases of upper-extremity complex regional pain syndrome or other sympathetically maintained pain. The block may be used to assess whether sympathetic activity contributes to symptoms or to provide treatment. The record should identify the target, side, indication, technique, and relevant response to the injection.
Report this code for the stellate ganglion injection, not for a block at another sympathetic target. It has a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral reporting with modifier 50, CMS pays 150%. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. CMS does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.
