CPT® Code 37615

The procedure described by CPT® Code 37615 involves the ligation of a major artery, specifically in the neck region, to effectively control bleeding that may occur due to a rupture or other traumatic injury to the blood vessel. Ligation is a surgical technique where a blood vessel is tied off to prevent blood flow, which is critical in managing significant hemorrhage. During this procedure, the physician first makes an incision to access the site of injury, allowing for exploration of the affected area. This exploration is essential to evacuate any pooled blood and to identify the precise source of the bleeding. 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. This dissection is crucial as it provides the necessary access for the placement of a suture ligature or wire band. The ligation is performed by tying off the artery with sutures or a thin wire at a point that is proximal to the rupture, effectively stopping the flow of blood and allowing for stabilization of the patient. This procedure is vital in emergency situations where rapid control of bleeding is necessary to prevent further complications or loss of life.
