Airway procedure
About 31730: Percutaneous tracheal stenosis dilation
Percutaneous tracheal stenosis dilation introduces a wire or catheter into the trachea to widen a narrowed segment without open tracheoplasty.
This procedure uses percutaneous access to introduce a wire or catheter into a narrowed tracheal segment and dilate the stenosis. It may be performed by an otolaryngologist or thoracic surgeon in an operating room or other procedural setting when a tracheal narrowing requires dilation. The record should identify the stenosis, the percutaneous approach, and the wire or catheter dilation performed.
Report 31730 for this percutaneous tracheal dilation, rather than for bronchoscopic dilation or open tracheal reconstruction. It has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same 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 for this code. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
