Thoracic surgery

About 21812: Rib fracture fixation, four to six ribs

Reports open stabilization with internal fixation of four to six fractured ribs, commonly performed for multiple displaced fractures or flail chest.

This service involves surgically exposing fractured ribs and stabilizing four to six ribs with internal fixation, such as plates. Thoracic or trauma surgeons commonly perform it in a hospital setting for selected patients with multiple displaced rib fractures or flail chest. Thoracoscopy performed as part of the stabilization is included. The code level is based on the number of ribs treated, not simply the total number of fractures identified.

The operative report should identify the ribs stabilized, confirm internal fixation, and describe the approach and any thoracoscopic assistance. Choose the sibling code for one to three ribs or seven or more ribs when the treated-rib count falls in those ranges. This minor procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
