CPT® Code 39540

The procedure described by CPT® Code 39540 involves the surgical repair of a traumatic diaphragmatic hernia, which is a condition where there is a rupture in the diaphragm allowing abdominal contents to move into the thoracic cavity. This type of hernia is not present at birth (non-neonatal) and is typically the result of acute trauma. The most frequent cause of such a hernia is blunt force trauma, often resulting from incidents like motor vehicle accidents. However, it can also occur due to falls or penetrating injuries to the abdomen. The surgical approach to repair the hernia is primarily through the abdominal cavity, although in some cases, a thoracic or a combined approach may be necessary. During the procedure, the surgeon opens and explores the abdomen and/or thorax to assess the extent of the injury. The torn edges of the diaphragm are carefully separated from surrounding tissues, and the herniated abdominal contents are gently repositioned back into the abdominal cavity. The repair of the diaphragm is typically accomplished using sutures, which may be reinforced with either a fascial graft or a synthetic patch, depending on the specific circumstances of the injury. It is important to note that CPT® Code 39540 is specifically designated for the repair of acute traumatic diaphragmatic hernias, while CPT® Code 39541 is used for chronic cases, which may involve additional complications such as diaphragm atrophy requiring a synthetic patch for repair.
