Major laceration of abdominal aorta, subsequent encounter

This code signifies a significant tear or cut in the abdominal aorta, the body's largest artery, specifically during a follow-up visit for care related to the initial injury. Such an injury is life-threatening and typically results from severe trauma. The subsequent encounter indicates ongoing management, monitoring, or treatment after the initial acute phase.

Apply this code for encounters where a patient is receiving follow-up care for a previously diagnosed major laceration of the abdominal aorta. This includes visits for wound checks, post-operative care, monitoring for complications, or ongoing treatment related to the initial traumatic injury. It is not for the initial acute presentation of the injury.

• Ensure the "D" seventh character is appropriate for a subsequent encounter, indicating active treatment or follow-up.
• Always code the underlying cause of the trauma (e.g., motor vehicle accident, penetrating injury) in addition to this code.
• Do not use this code for a minor laceration or for an initial encounter.
