Injury to thoracic aorta

This code represents a traumatic injury specifically affecting the thoracic segment of the aorta. This can include contusions, lacerations, ruptures, or dissections of the aorta within the chest cavity, often resulting from blunt or penetrating trauma. Such injuries are life-threatening due to the potential for massive hemorrhage and circulatory compromise.

Use this code when documentation clearly indicates a traumatic injury to the thoracic aorta, such as from a motor vehicle accident, fall from height, or penetrating wound to the chest. Supporting documentation should specify the anatomical location (thoracic aorta) and the traumatic nature of the injury.

• Differentiate from injuries to other aortic segments (e.g., abdominal aorta) or other great vessels.
• Always code the external cause of injury (E-code) in conjunction with this diagnosis.
• Specify the type of injury (e.g., rupture, laceration) if documented, using more specific codes if available within the 901 series.
