ICD-10 Code I71.3 – Abdominal aortic aneurysm, ruptured (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I71.3 – Abdominal aortic aneurysm, ruptured
What it is
I71.3 identifies a ruptured aneurysm of the abdominal aorta, meaning the weakened aortic wall has torn or leaked. This is a life-threatening vascular emergency and requires immediate documentation of rupture.
Clinical signs
Common findings include sudden abdominal, back, or flank pain, hypotension, and signs of shock. Clinical features vary; refer to documentation for imaging or operative confirmation of rupture.
When to use this code
Use I71.3 when the record clearly states an abdominal aortic aneurysm with rupture. This may be supported by imaging, emergency department notes, operative reports, or discharge diagnoses. You should code the ruptured condition when documentation links the aneurysm to the rupture.
Do not use for
Do not use this code for an abdominal aortic aneurysm without rupture, or when rupture is not documented. Check documentation if the record only describes pain, suspected aneurysm, or post-repair status.
Coding tip
Code the rupture only when the provider documents it clearly; if wording is unclear, query for confirmation.
