CPT® Code 21632

Deleted

The CPT® Code 21632 refers to a surgical procedure known as a radical resection of the sternum, which is performed in conjunction with a mediastinal lymphadenectomy. This procedure is typically indicated for patients with certain thoracic conditions that necessitate the removal of the sternum and associated lymph nodes in the mediastinum, the central compartment of the thoracic cavity. The surgery is conducted under general anesthesia, ensuring that the patient is fully unconscious and pain-free throughout the operation. The process begins with the creation of a surgical incision over the sternum and upper chest, allowing the surgeon to access the underlying structures. The soft tissue surrounding the sternum is carefully dissected to expose the bone. Once the sternum is identified, specialized surgical saws and instruments are employed to completely remove it from the body. During this procedure, the ribs may also need to be detached from the sternum and cleaned of any necrotic or diseased tissue, a process known as debridement. In some cases, the use of internal fixation devices may be required to stabilize the chest wall after the sternum is removed. It is important to note that if the physician performs a mediastinal lymphadenectomy, which involves the removal of lymph nodes in the mediastinum, this procedure is reported using CPT® Code 21632. The closure of all incisions is a critical final step in the procedure, ensuring proper healing and minimizing the risk of complications.
