CPT® Code 37618

The procedure described by CPT® Code 37618 involves the ligation of a major artery in an extremity, which is typically performed to control significant bleeding resulting from a rupture or traumatic injury to the blood vessel. In this context, "ligation" refers to the surgical technique of tying off the artery to prevent further blood loss. The procedure begins with the physician making an incision to access the site of injury, allowing for exploration of the affected area. During this exploration, any accumulated blood is evacuated, and the source of the bleeding is identified. A vascular clamp is then applied to temporarily control the bleeding, enabling the surgeon to thoroughly examine the site for any additional injuries that may require attention. Once the area is adequately assessed, the artery is carefully dissected away from the surrounding tissues to facilitate the placement of a suture ligature or wire band. This dissection is crucial as it ensures that the artery can be securely tied off at a point proximal to the rupture, effectively stopping the flow of blood and preventing further complications. It is important to note that this specific code is designated for ligation procedures performed on major arteries located in the arms or legs. For ligation of major arteries in other anatomical locations, such as the neck, chest, or abdomen, different CPT® codes are utilized, specifically 37615, 37616, and 37617, respectively. This distinction is essential for accurate coding and billing purposes.
