Other injury of abdominal aorta, sequela

This code signifies a long-term or late-effect complication resulting from a past injury to the abdominal aorta, other than those specifically classified elsewhere. It indicates that the patient is experiencing ongoing health issues directly attributable to a previous traumatic event affecting this major blood vessel.

Apply this code when documenting conditions such as chronic abdominal aortic dissection, pseudoaneurysm, or persistent stenosis that developed as a direct consequence of an earlier, resolved injury. This is appropriate for follow-up encounters where the initial acute injury has healed but its lasting impact is being treated.

• Always use in conjunction with an external cause code to fully describe the circumstances of the original injury.
• Ensure documentation clearly links the current condition to a past abdominal aortic trauma.
• Verify that the "S" seventh character is appropriate for a sequela encounter, indicating a late effect.
