Late effect of injury to blood vessel of thorax, abdomen, and pelvis

This code signifies a long-term health problem resulting from a past injury to a blood vessel located within the chest, abdominal, or pelvic regions. These late effects can manifest months or years after the initial trauma and include conditions such as chronic arterial occlusion, pseudoaneurysm, arteriovenous fistula, or chronic venous insufficiency stemming from the original vascular damage.

Apply this code when documenting a current condition that is a direct, persistent consequence of a previous injury to a thoracic, abdominal, or pelvic blood vessel. This typically applies when the acute phase of the original injury has passed, and the patient is now being treated for a residual complication. Documentation should clearly link the current vascular pathology to a prior traumatic event.

• Always sequence this code after the definitive diagnosis describing the specific late effect (e.g., chronic arterial occlusion, pseudoaneurysm).
• Ensure documentation explicitly states the vascular injury is a late effect and specifies the anatomical region (thorax, abdomen, or pelvis).
• Do not use for acute vascular injuries; those are coded with acute injury codes from the 900-904 series.
