CPT® Code 22905

Radical resection of a tumor, specifically a soft tissue tumor of the abdominal wall measuring 5 cm or greater, is a surgical procedure aimed at completely removing malignant neoplasms, such as sarcomas, as well as potentially benign tumors or those of indeterminate nature. The term "soft tissue" encompasses various structures, including muscles, tendons, fat, blood vessels, lymph vessels, nerves, and the tissues surrounding joints. The procedure begins with the creation of a skin incision directly over the tumor or the elevation of a skin flap to access the tumor site. Following this, the surgeon meticulously dissects the overlying subcutaneous and soft tissues to expose the tumor. 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 approach is critical in cases of malignancy, as it aims to eliminate all involved soft tissue, which may include adjacent muscles, nerves, and blood vessels. 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, and the surgical wound can be closed in layers, or additional reconstructive procedures may be performed as needed. For tumors measuring less than 5 cm, the appropriate code to use is 22904, while 22905 is designated for tumors that are 5 cm or greater.
