ICD-10 Code I71.62 – Paravisceral aneurysm of the thoracoabdominal aorta, without rupture (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I71.62 – Paravisceral aneurysm of the thoracoabdominal aorta, without rupture
What it is
This code identifies a thoracoabdominal aortic aneurysm located in the paravisceral segment, meaning the enlarged artery involves the aorta near the major abdominal branches. It is used when there is no rupture documented.
Clinical signs
Clinical features vary; refer to documentation. Imaging may show focal aortic dilatation near the visceral branch vessels, and the record should state that the aneurysm is present without rupture.
When to use this code
Use I71.62 when the provider documents a paravisceral aneurysm of the thoracoabdominal aorta and specifically notes no rupture. Choose this code from imaging, operative, or specialist documentation that clearly identifies the aneurysm location. If the site is described differently or rupture is mentioned, check documentation before coding.
Do not use for
Do not use this code for ruptured aneurysm, unspecified aortic aneurysm, or aneurysms in a different aortic segment. Check documentation if the record does not clearly identify the paravisceral thoracoabdominal location.
Coding tip
Confirm both anatomy and rupture status in the provider note before assigning I71.62.
