Nervous system surgery
About 64804: Cervicothoracic sympathetic chain surgery
Cervicothoracic sympathectomy interrupts sympathetic nerve tissue at the neck–chest junction for selected upper-extremity conditions.
Cervicothoracic sympathectomy interrupts or removes sympathetic nerve tissue at the junction of the cervical and thoracic regions. Surgeons may perform it for severe upper-extremity hyperhidrosis or selected vasospastic or pain conditions when targeted interruption of sympathetic outflow is intended. The operation is generally performed in an operating room. The operative report should identify the side and sympathetic structures treated.
Report 64804 when the documented operative work is at the cervicothoracic level, rather than cervical-only, lower thoracic or lumbar, or limited to a hand artery. Document the indication, laterality, anatomic extent, and technique to support the level treated. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. For bilateral work, modifier 50 is paid at 150%. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
