Thoracic surgery
About 39540: Chronic traumatic diaphragmatic hernia repair
Repair a chronic diaphragmatic hernia caused by trauma, typically by reducing herniated abdominal contents and closing the diaphragmatic defect.
This operation repairs a diaphragmatic hernia that developed after trauma and is treated in the chronic phase. The surgeon exposes the diaphragm through an appropriate operative approach, returns displaced abdominal contents to the abdomen, and closes the defect. It is generally performed by a thoracic or general surgeon in a hospital operating room. The distinguishing feature is the chronic traumatic origin; an acute traumatic hernia and a nontraumatic hernia are reported with different codes.
Report the service when the operative documentation supports repair of a chronic, trauma-related diaphragmatic hernia. The 90-day global period includes the day-before preoperative visit and related postoperative care during that period. 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. Modifier 50 is inappropriate for this code. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
