CPT® Code 21810

Deleted

The CPT® Code 21810 refers to the treatment of rib fractures that necessitate the use of external fixation, specifically in cases of flail chest. Flail chest is a critical condition that arises from severe blunt trauma to the chest, leading to multiple fractures of the ribs, which can occur both anteriorly and posteriorly. This injury results in a segment of the thoracic cage becoming detached from the rest of the chest wall, causing it to fail in its normal movement and expansion during respiration. The treatment involves surgical intervention where an incision is made over the thoracic area to expose the fractured ribs. In some cases, external fixation can be applied using a closed technique, guided by radiographic imaging to ensure proper placement. The primary goal of this procedure is to stabilize the fractured rib segments, thereby restoring the integrity of the chest wall and facilitating normal respiratory function.
