CPT® Code 38530

The procedure described by CPT® Code 38530 involves the open biopsy or excision of lymph nodes, specifically targeting the internal mammary nodes. This surgical intervention is typically indicated when there is a need to evaluate or treat conditions affecting the lymphatic system, particularly in the context of breast cancer or other malignancies. The internal mammary nodes are located deep within the chest, adjacent to the sternum, and are part of the lymphatic drainage system of the breast. The procedure requires careful dissection to access these nodes while minimizing damage to surrounding structures, such as nerves and blood vessels. The surgical approach involves making an incision in the skin of the chest, detaching the overlying breast tissue from the pectoralis major muscle, and exposing the internal mammary nodes by dividing the pectoralis major and intercostal muscles. This meticulous technique allows for the removal of one or more lymph nodes or the collection of tissue samples for pathological evaluation, which is crucial for accurate diagnosis and treatment planning.
