Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 31631 covers

An interventional pulmonologist or thoracic surgeon uses a rigid or flexible bronchoscope to place a stent in the trachea, often to support an airway narrowed by stenosis or tumor. The procedure may include dilation to prepare or open the airway, and fluoroscopic guidance may be used. It is typically performed in a hospital or other facility setting.

Report 31631 for tracheal stent placement, not for dilation alone or placement of a bronchial stent. The operative report should identify the tracheal site, the stent placement, and any dilation or imaging guidance performed. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.
