CPT® Code 23220

Radical resection of the proximal humerus, as described by CPT® Code 23220, is a surgical procedure primarily indicated for the removal of malignant tumors, although it may also be necessary for benign tumors or those of indeterminate nature. The procedure begins with the creation of a skin incision directly over the tumor located in the proximal humerus, or alternatively, a skin flap may be elevated to provide access. The surgeon meticulously dissects the overlying tissue to expose the tumor, ensuring that all affected bone and cartilage in the proximal humerus are resected. This comprehensive approach involves the removal of the tumor en bloc, which means the tumor is excised along with a wide margin of healthy surrounding tissue to ensure complete removal of cancerous cells. The radical resection encompasses not only the bone but also all involved soft tissues, which may include muscles, tendons, fat, blood vessels, lymph vessels, nerves, and any tissues surrounding the joints. To confirm that the surgical margins are free of tumor cells, a separately reportable frozen section may be performed during the procedure. If any margins are found to contain malignancy, additional tissue will be excised until all margins are confirmed to be clear of tumor cells. Post-surgery, drains may be placed as necessary to manage fluid accumulation, and the surgical wound can be closed in layers, or additional reconstructive procedures may be performed if required.
