CPT® Code 21620

The procedure described by CPT® Code 21620 refers to the surgical removal of a portion of the sternum, known as an ostectomy of the sternum. This operation is typically performed to address various medical conditions that may affect the sternum, such as tumors, infections, or other pathologies that necessitate the removal of a segment of this bone. The sternum, commonly referred to as the breastbone, is a flat bone located in the center of the chest, serving as a critical component of the rib cage, which protects vital organs such as the heart and lungs. During the procedure, the physician makes an incision in the chest above the sternum to gain access to the bone. Once the sternum is identified, surrounding tissues are carefully dissected to expose the area of interest. Surgical instruments, including saws, are employed to excise the specified portion of the sternum. After the removal, the remaining bone edges are smoothed to promote healing and reduce the risk of complications. The surgical site is then irrigated to ensure cleanliness, and the incisions are meticulously closed to facilitate recovery. This procedure requires careful planning and execution to minimize risks and ensure optimal outcomes for the patient.
