CPT® Code 49904

Omental flap procedures, specifically CPT® Code 49904, involve the use of the omentum, a fold of peritoneum extending from the stomach, in reconstructive surgery. This technique is particularly beneficial for addressing significant defects in soft and connective tissues, which may arise from various causes such as trauma, disease, or surgical excision of tissue. The procedure described by CPT® Code 49904 focuses on the application of an extra-abdominal omental flap, which is utilized to reconstruct defects located in the sternum or chest wall. The process begins with an upper midline abdominal incision that allows for the exposure of the omentum. Surgeons assess the omentum to identify the dominant blood vessels that will ensure adequate vascular supply and flap length necessary for effective reconstruction. Following careful dissection, the omentum is mobilized and positioned over the chest defect, ensuring that it is free from tension and that blood flow remains unobstructed. This method not only aids in the physical restoration of the affected area but also plays a crucial role in promoting healing and recovery in patients with significant tissue loss.
