ICD-10 Code I72.2 – Aneurysm of renal artery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I72.2 – Aneurysm of renal artery
What it is
I72.2 identifies a localized abnormal dilation of the renal artery. Use it when the record documents a true aneurysm affecting one or both renal arteries.
Clinical signs
Clinical features vary; refer to documentation. Renal artery aneurysms are often incidental findings on imaging, but they may be associated with flank pain, hematuria, hypertension, or rupture-related symptoms.
When to use this code
Use this code when the provider documents aneurysm of the renal artery, including incidental imaging findings or follow-up of a known aneurysm. It also fits cases where the aneurysm is the reason for specialist evaluation, surveillance, or intervention planning.
Confirm that the documentation names the renal artery specifically. If the record only mentions renal vascular disease, stenosis, or another arterial disorder, check documentation before assigning I72.2.
Do not use for
Do not use this code for renal artery stenosis, dissection, or general aneurysm elsewhere in the aorta or peripheral arteries. Check documentation if the vessel site is unclear.
Coding tip
Code the exact artery named in the note and verify laterality or multiplicity only when documented.
