Pulmonary endoscopy
About 31631: Bronchoscopy with tracheal stent placement
Report this service when bronchoscopy is used to place a stent in the trachea, including associated dilation when performed.
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.

31631 billing questions
How does 31631 differ from 31630?
31631 is for placing a stent in the trachea. Use 31630 for bronchoscopy with airway dilation or fracture reduction when no tracheal stent is placed.
When should 31636 be used instead?
31636 describes initial stent placement in a bronchus. The placement site distinguishes it from 31631, which is for the trachea.
Can diagnostic bronchoscopy be reported separately?
Related endoscopies performed together are subject to endoscopy family pricing. Document the distinct services performed; do not assume a diagnostic inspection is separately reportable merely because it was performed.
Is modifier 50 appropriate for stents placed on both sides?
No. The CMS bilateral adjustment does not apply to 31631, and modifier 50 is inappropriate for this code.
What documentation supports 31631?
Document the tracheal location, the stent placement, and any dilation or fluoroscopic guidance performed. The record should distinguish tracheal placement from bronchial stent placement.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for 31631. Co-surgeons and team surgery are not permitted.
