ICD-10 Code I71.61 – Supraceliac aneurysm of the thoracoabdominal aorta, without rupture (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I71.61 – Supraceliac aneurysm of the thoracoabdominal aorta, without rupture
What it is
This code identifies a thoracoabdominal aortic aneurysm located at the supraceliac segment, meaning the enlarged vessel is above the celiac artery and has not ruptured. Use it for documented aneurysmal dilation in this specific aortic location.
Clinical signs
Clinical features vary; refer to documentation. Patients may be asymptomatic, or the aneurysm may be found on imaging done for another reason. Diagnosis is typically based on radiology or specialist assessment describing the supraceliac thoracoabdominal aorta.
When to use this code
Use I71.61 when the record clearly states a supraceliac thoracoabdominal aortic aneurysm without rupture. It is appropriate for confirmed imaging, operative, or problem-list documentation that specifies this exact segment. Code the condition only when the aneurysm is present and unruptured.
Do not use for
Do not use this code for ruptured aneurysm, because a different code applies. Check documentation if the aneurysm is in another aortic segment or if the note only mentions aortic dilation, ectasia, or dissection.
Coding tip
Confirm both location and rupture status in the report before assigning I71.61.
