CPT® Code 25170

Radical resection of a tumor in the radius or ulna, as described by CPT® Code 25170, is a surgical procedure primarily indicated for the removal of malignant neoplasms. However, it may also be necessary for benign tumors or tumors of indeterminate nature. The procedure begins with the creation of a skin incision directly over the tumor site, or alternatively, a skin flap may be elevated to provide access. The surgeon meticulously dissects the overlying tissue to expose the tumor. During the resection, all bone and cartilage in the radius or ulna that is involved with the tumor is excised. This process involves removing the tumor en bloc, which means the tumor is taken out in one piece along with a wide margin of surrounding healthy tissue to ensure complete removal. The radical resection encompasses not only the excision of the tumor but also all affected soft tissues, which may include muscles, tendons, fat, blood vessels, lymph vessels, nerves, and adjacent joint tissues. To confirm that the surgical margins are free of tumor cells, a separately reportable frozen section may be performed. If any margins are found to contain malignancy, additional tissue will be excised until all margins are clear. Post-surgery, drains may be placed as necessary, and the surgical wound can be closed in layers, or additional reconstructive procedures may be performed if required.
