CPT® Code 38500

A biopsy or excision of one or more superficial lymph nodes is a surgical procedure that involves the removal or sampling of lymphatic tissue for diagnostic purposes. Superficial lymph nodes, which include those located in the cervical, inguinal, and axillary regions, are situated close to the skin's surface, allowing for easier access with minimal dissection of the overlying tissues. In the context of CPT® Code 38500, the procedure is classified as an open biopsy or excision, meaning that a surgical incision is made to access the lymph node directly. The process begins with the identification of the lymph node through palpation, which is the act of feeling the lymph node through the skin. Following this, the skin over the lymph node is disinfected to reduce the risk of infection, and a local anesthetic is administered to numb the area, ensuring patient comfort during the procedure. Once the area is prepared, an incision is made in the skin to expose the lymph node. If an excisional biopsy is performed, the lymph node is carefully dissected free from the surrounding tissue and completely removed for further analysis. Alternatively, if an incisional biopsy is conducted, only a portion of the lymph node is taken for sampling. The excised lymph node or the obtained tissue sample is then sent for laboratory analysis, which is reported separately. This procedure is essential for diagnosing various conditions, including infections, autoimmune diseases, and malignancies, by providing critical information about the lymphatic system's status.
