Thoracic surgery
About 21813: Open fixation of seven or more rib fractures
Reports operative internal fixation of seven or more rib fractures, including thoracoscopic visualization when performed, for patients requiring surgical stabilization.
This code describes operative stabilization of seven or more fractured ribs using internal fixation. Thoracic or trauma surgeons typically perform the procedure in a hospital operating room for patients whose rib injuries require surgical stabilization. Thoracoscopic visualization, when used during the operation, is included in the service. The code is selected by the number of ribs treated with fixation, not simply the total number of fractured ribs documented.
The operative report should identify the ribs treated and describe the fixation performed. This is a minor procedure with a 0-day global period, so same-day preoperative and postoperative care is included. When another procedure is performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple-procedure reduction. For bilateral reporting with modifier 50, CMS pays this procedure at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
