0.000What This Code Means
A weakened, bulging section of the artery that supplies blood to the kidney, which requires monitoring to prevent rupture.
Coding Tips
- •Document whether the aneurysm is ruptured or non-ruptured, as this affects code selection
- •Note if the condition affects one or both kidneys when applicable
Clinical Significance
Renal artery aneurysm carries risk of rupture (particularly during pregnancy), renal artery thrombosis, and renovascular hypertension. Though often asymptomatic and discovered incidentally, these aneurysms require surveillance and may necessitate intervention when exceeding 2 cm or becoming symptomatic. Accurate coding captures this vascular disease burden for risk adjustment.
Documentation Requirements
- ✓Documentation of renal artery aneurysm with imaging confirmation
- ✓Size measurement and any interval change
- ✓Laterality (right, left, or bilateral)
- ✓Type (true aneurysm vs pseudoaneurysm, saccular vs fusiform)
- ✓Associated conditions (renovascular hypertension, fibromuscular dysplasia)
- ✓Treatment plan (surveillance, embolization, surgical repair)
- ✓Assessment of renal function
