Minor laceration of thoracic aorta, initial encounter

This code signifies a superficial tear or cut in the wall of the thoracic aorta, the major artery carrying blood from the heart through the chest. It indicates that the injury is not a complete rupture or a major dissection, but rather a less severe form of damage to the aortic wall.

Apply this code for patients presenting with an acute, newly diagnosed minor laceration of the thoracic aorta, typically identified through imaging studies following blunt or penetrating trauma to the chest. This includes cases where the laceration is an incidental finding during workup for other injuries, provided it meets the criteria for a minor tear.

• Ensure documentation clearly specifies "minor laceration" and "thoracic aorta" to support code assignment.
• Verify that this is the initial encounter for treatment of this specific injury; subsequent encounters will require different seventh characters.
• Always code any associated external cause of injury (e.g., motor vehicle accident, fall) to provide a complete clinical picture.
