What 31643 covers

A pulmonologist or interventional pulmonologist uses a rigid or flexible bronchoscope to guide a catheter through the airway for delivery of a radiopharmaceutical agent. The service is used in situations such as endobronchial brachytherapy for a lung tumor; the catheter placement is distinct from the subsequent radiation treatment. It is generally performed in a hospital or other facility equipped for therapeutic bronchoscopy and radiation procedures.

Report 31643 when the bronchoscopic catheter placement for agent delivery is performed. The procedure note should identify the catheter placement and its intended delivery purpose; a diagnostic airway inspection alone is not enough. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
