What 32556 covers
This service places a catheter percutaneously into the pleural space and leaves it in place for drainage, without imaging guidance. It is used to drain pleural fluid or air when a catheter is needed rather than a one-time needle aspiration. Pulmonologists, thoracic surgeons, and other physicians who manage pleural disease may perform it at the bedside or in a procedure setting. The method and documentation should support that the catheter was inserted into the pleural space and that imaging guidance was not used.
Report 32556 for the catheter placement, not for a thoracentesis that removes fluid without leaving a catheter. Document the indication, side, catheter placement, and whether imaging guidance was used; imaging-guided placement is represented by 32557. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted, and co-surgeon and team-surgery payment are not permitted.
