CPT® Code 24920

An amputation of the arm through the humerus, specifically classified under CPT® Code 24920, refers to a surgical procedure where the arm is removed at the level of the humerus using an open, circular technique, commonly known as a guillotine amputation. This type of amputation is typically indicated for patients with severe trauma, malignancy, or other conditions that necessitate the removal of the arm above the elbow. The procedure involves careful planning and execution to ensure that the surrounding tissues, including skin, muscle, blood vessels, and nerves, are managed appropriately to promote healing and minimize complications. The patient is positioned with the shoulder slightly elevated on the operative side to facilitate access to the surgical site. The surgical team marks incision lines on the skin, which guide the creation of a circular incision around the arm. This method allows for the removal of the arm while preserving as much surrounding tissue as possible, which is crucial for postoperative recovery and rehabilitation. The procedure is characterized by its systematic approach to dissection and transection of tissues, ensuring that all necessary structures are addressed to achieve a successful amputation and closure.
