What 31775 covers

This service involves removing a segment of bronchus and reconstructing the airway, commonly by joining the remaining bronchial ends. A thoracic surgeon may perform it for a localized bronchial tumor or other focal disease when sleeve resection can remove the affected airway while preserving more lung than a larger lung resection. The operation is performed in a surgical setting and may involve open or minimally invasive thoracic techniques.

Report the code when the operative work includes bronchial sleeve resection and reconstruction, not for bronchial repair or grafting without that resection. The operative report should identify the bronchial site, the segment removed, and the reconstruction performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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. Bilateral adjustment is inappropriate. Assistant-at-surgery payment may be available; 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.

How to choose

31770Bronchial repair
31775 includes bronchial sleeve resection with reconstruction. 31770 is for bronchial repair or grafting without that sleeve-resection work.
31766Airway reconstruction
Choose 31766 when reconstruction involves the carina. This code describes bronchial sleeve resection and reconstruction rather than carinal reconstruction.
31760Tracheoplasty
31760 concerns intrathoracic tracheoplasty. Use 31775 when the operative work is bronchial sleeve resection and reconstruction.

31775 billing questions

How does this differ from 31770?

Use 31775 for bronchial reconstruction that includes sleeve resection. Code 31770 represents bronchial repair or grafting without that sleeve-resection service.

What operative documentation supports 31775?

The operative report should describe the bronchial segment removed and how the remaining airway was reconstructed. A diagnosis alone does not establish that sleeve resection and reconstruction were performed.

Can modifier 50 be used for bilateral bronchial work?

No. CMS identifies bilateral adjustment as inappropriate for this code; its descriptor or anatomy does not support modifier 50.

How does the multiple-procedure rule affect payment?

When this service is performed with other procedures in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be available. Co-surgeons and team surgery are not permitted for this code under the CMS facts provided.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

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.
