CPT® Code 38525

The procedure described by CPT® Code 38525 involves the open biopsy or excision of deep axillary lymph nodes, which are critical components of the lymphatic system located in the axilla (armpit area). Lymph nodes play a vital role in the immune response by filtering lymph fluid and trapping pathogens, such as bacteria and viruses. The axillary lymph nodes are categorized into five distinct groups: lateral, subscapular, pectoral, central, and apical (infraclavicular) nodes. Among these, the central and apical nodes are classified as deep nodes, which are the focus of this procedure. During the operation, a surgical incision is made in the axilla directly over the affected deep axillary nodes. The surgeon carefully dissects through the surrounding soft tissues, ensuring the protection of nearby nerves and blood vessels to minimize complications. The goal of this procedure is to either completely remove one or more deep axillary lymph nodes or to obtain tissue samples for further pathological examination. This is crucial for diagnosing conditions such as cancer, where lymph node involvement can significantly influence treatment decisions. The excised nodes or tissue samples are subsequently sent to a laboratory for detailed analysis, which is essential for determining the presence of malignancy or other pathological conditions.
