CPT® Code 27329

Radical resection of a tumor, specifically a soft tissue tumor located in the thigh or knee area, is a surgical procedure denoted by CPT® Code 27329. This procedure is indicated for tumors that are less than 5 cm in size and may include various types of soft tissue, such as muscles, tendons, fat, blood vessels, lymph vessels, nerves, and the tissues surrounding joints. The term "radical resection" refers to the comprehensive removal of the tumor along with a significant margin of surrounding healthy tissue to ensure complete excision of any malignant cells. While this procedure is primarily performed for malignant neoplasms, such as sarcomas, it may also be necessary for benign tumors or those of uncertain nature. The surgical approach typically involves making an incision over the tumor or creating a skin flap to access the tumor effectively. The goal of the procedure is to excise the tumor en bloc, which means removing it in one piece along with a wide margin of healthy tissue to minimize the risk of recurrence. Additionally, a frozen section may be performed during the procedure to assess the margins for tumor cells, ensuring that all cancerous tissue has been removed. If any malignancy is detected at the margins, further tissue removal is conducted until clear margins are achieved. Post-operative care may include the placement of drains as needed, and the surgical wound is usually closed in layers, or reconstructive procedures may be performed if necessary.
