What 31630 covers
This therapeutic bronchoscopy widens a narrowed segment of the trachea or a bronchus, such as scar-related airway stenosis. An interventional pulmonologist, thoracic surgeon, or otolaryngologist may perform it with a rigid or flexible bronchoscope in an operating room or endoscopy suite. The service involves treating the narrowing to improve airway caliber; stent placement is reported with a different code.
Report 31630 when the provider performs airway dilation, not for diagnostic inspection alone. Documentation should identify the treated airway segment, the narrowing, and the dilation performed. The 0-day global period includes same-day preoperative and postoperative care. When related endoscopies are performed together, CMS endoscopy-family pricing applies, so they are not each paid as standalone procedures. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgery and team surgery are not permitted.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

31630 billing questions
How is 31630 different from a bronchoscopy with stent placement?
Use 31630 for dilation without stent placement. When a tracheal or bronchial stent is placed, consider the code that describes the stent procedure and airway site.
Can diagnostic bronchoscopy be reported separately with 31630?
Diagnostic inspection used to reach and assess the narrowing is generally part of the therapeutic bronchoscopy. The record should show the airway dilation, not just an examination.
How are related endoscopies paid when performed together?
CMS endoscopy-family pricing applies to related endoscopies performed together. The procedures are not each paid at their standalone allowance.
Should modifier 50 be used for dilation on both sides?
No. The CMS bilateral adjustment does not apply to 31630, and modifier 50 is inappropriate.
What documentation supports reporting 31630?
Document the location of the tracheal or bronchial narrowing and the therapeutic dilation performed. Same-day preoperative and postoperative care is included in the 0-day global period.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
