What 32400 covers
A clinician passes a needle through the chest wall to obtain pleural tissue for diagnostic evaluation. Pulmonologists, interventional radiologists, and thoracic surgeons may perform the procedure, often in a hospital setting. The target is the pleura, not a lung nodule or mediastinal mass; aspiration of pleural fluid alone is a different service.
Report this code when the needle biopsy samples pleural tissue, and document the target, percutaneous approach, and reason tissue was needed. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
