Thoracic surgery
About 31770: Bronchial repair or graft without resection
Reports surgical repair or grafting of a bronchus when the bronchial segment is repaired without resecting a portion of it.
This code describes operative repair or grafting of a bronchus while leaving the involved bronchial segment in place. A thoracic surgeon may perform it for a bronchial defect or injury requiring reconstruction, such as damage from trauma or an operative complication. The procedure is performed in an operating room, generally in a hospital setting; the operative report should identify the bronchus and describe the repair or graft and the reason it was needed.
Choose this code when the bronchus is repaired or grafted without bronchial resection. Document the site, the repair or graft performed, and whether any bronchial tissue was removed; resection changes the code selection. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery services may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
