Thoracic surgery
About 21700: Scalene muscle division without rib resection
Reports surgical division of scalene muscles, commonly for thoracic outlet decompression, when the operation does not include cervical rib resection.
The surgeon divides scalene muscle fibers in the neck to relieve compression associated with thoracic outlet syndrome, such as pressure affecting the brachial plexus or subclavian vessels. The operation is performed by a surgeon, commonly in a hospital operating room. This code describes the scalene release without removal of a cervical rib; a rib-resection operation falls under a different code in the same family.
Choose the code from the operation performed, documenting the indication, side, scalene muscles addressed, and whether a cervical rib was removed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.
