ICD-10 Code I71.51 – Supraceliac aneurysm of the thoracoabdominal aorta, ruptured (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I71.51 – Supraceliac aneurysm of the thoracoabdominal aorta, ruptured
What it is
This code identifies a ruptured aneurysm in the supraceliac segment of the thoracoabdominal aorta. Use it when documentation specifies this location and confirms rupture.
Clinical signs
Clinical features vary; refer to documentation. Rupture may be associated with sudden severe pain, hemodynamic instability, or imaging evidence of a thoracoabdominal aortic aneurysm with leak or rupture.
When to use this code
Use I71.51 when the provider documents a ruptured supraceliac thoracoabdominal aortic aneurysm. It is appropriate for inpatient, emergency, or operative records when the anatomic site and rupture are clearly stated. Check documentation if the report only says thoracoabdominal aneurysm without the supraceliac detail.
Do not use for
Do not use this code for an unruptured aneurysm, a different aortic segment, or nonspecific thoracic or abdominal aortic aneurysm documentation. Check documentation if rupture is not explicitly confirmed.
Coding tip
Code the exact aortic location and rupture status together; if either element is missing, query the record before assigning I71.51.
