CPT® Code 21936

Radical resection of a tumor, specifically a soft tissue tumor located in the back or flank region, is a surgical procedure denoted by CPT® Code 21936. This procedure is indicated for tumors that measure 5 cm or greater and may include various types of soft tissue, such as muscles, tendons, fat, blood vessels, lymph vessels, nerves, and the tissues surrounding joints. Soft tissue tumors can be classified as benign or malignant, with radical resection primarily performed for malignant neoplasms, such as sarcomas. However, benign tumors or those of indeterminate nature may also necessitate this extensive surgical intervention. The process begins with the creation of a skin incision over the tumor site or the elevation of a skin flap to access the tumor. The surgeon meticulously dissects the overlying subcutaneous and soft tissues to expose the tumor mass. The radical resection entails the en bloc removal of the tumor along with a wide margin of surrounding healthy tissue to ensure complete excision. This procedure may involve the excision of adjacent muscles, nerves, and blood vessels, depending on the tumor's location and extent. To confirm that all 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 clear margins are achieved. Post-surgery, drains may be placed as necessary, and the surgical wound is typically closed in layers, although separate reconstructive procedures may also be performed if required. For tumors measuring less than 5 cm, CPT® Code 21935 should be utilized.
