ICD-10 Code I71.52 – Paravisceral aneurysm of the thoracoabdominal aorta, ruptured (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I71.52 – Paravisceral aneurysm of the thoracoabdominal aorta, ruptured
What it is
This code identifies a ruptured aneurysm in the paravisceral segment of the thoracoabdominal aorta. Use it when documentation specifies both the aneurysm location and that rupture has occurred.
Clinical signs
Clinical features vary; refer to documentation. Rupture is typically documented with acute pain, hemodynamic instability, or imaging and operative findings confirming a torn aneurysm.
When to use this code
Use I71.52 when the provider documents a paravisceral thoracoabdominal aortic aneurysm with rupture. This applies to emergency, inpatient, or surgical records that clearly identify the site and ruptured status. If the record only says aneurysm or a different aortic segment, check documentation.
Do not use for
Do not use this code for an unruptured aneurysm, a dissection without aneurysm rupture, or aneurysms in other aortic locations. Check documentation if the note is nonspecific.
Coding tip
Code the exact aortic segment and rupture status together; if either is unclear, query the provider.
