What 31634 covers

During this procedure, a pulmonologist or other bronchoscopist passes a flexible or rigid bronchoscope into the airways and uses a balloon catheter to temporarily occlude selected branches. The clinician observes the effect on an air leak, often through a connected chest drainage system, to help identify the airway responsible. This assessment may be used when a patient has a persistent leak, such as after lung surgery or with a bronchopleural fistula, and localization could guide treatment planning.

Report the service when balloon occlusion and air-leak assessment are performed, rather than for airway inspection alone or airway dilation. The record should support the clinical reason for testing, the airways occluded, and the observed leak response or measurements. CMS assigns 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. CMS may pay for an assistant at surgery; co-surgeons 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.

31634 billing questions

When is 31634 more appropriate than a diagnostic bronchoscopy code?

Use 31634 when balloon occlusion is performed to assess an air leak. Airway inspection without that assessment is a different service.

What documentation supports reporting 31634?

Document the indication for air-leak localization, the airway branches occluded, and the leak response or measurements observed during the test.

Can modifier 50 be used when both lungs are assessed?

No. CMS identifies bilateral adjustment as inappropriate for this code.

How does CMS price related endoscopies performed in the same session?

Endoscopy family pricing applies when related endoscopies are performed together.

Can an assistant, co-surgeon, or surgical team be reported?

An assistant at surgery may be paid. Co-surgeons and team surgery are not permitted.

What does the 0-day global period include?

Same-day preoperative and postoperative care is included in the procedure.

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.
