ICD-10 Code I71.41 – Pararenal abdominal aortic aneurysm, without rupture (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I71.41 – Pararenal abdominal aortic aneurysm, without rupture
What it is
This code identifies an abdominal aortic aneurysm located near the renal arteries and documented as not ruptured. Use it when the aneurysm is specifically described as pararenal and there is no mention of rupture.
Clinical signs
Clinical features may be absent, or patients may have nonspecific abdominal, back, or flank discomfort. Imaging usually confirms the aneurysm location and extent; clinical features vary, refer to documentation.
When to use this code
Use I71.41 when the provider documents a pararenal abdominal aortic aneurysm without rupture, including imaging-confirmed cases. It is appropriate for encounters focused on surveillance, evaluation, or follow-up of the aneurysm. Verify the anatomic descriptor and rupture status in the record.
Do not use for
Do not use this code if the aneurysm is ruptured, because rupture requires a different code. Also avoid it when the documentation only states abdominal aortic aneurysm without specifying a pararenal location; check documentation.
Coding tip
Code the exact aneurysm location and rupture status from the provider’s documentation, not from assumptions based on imaging alone.
