Is I72.2 an HCC code?
I72.2 has no mapping under the current CMS-HCC V28 community payment model. I72.2 has a separate mapping under the CMS-HCC ESRD model (HCC 108 (Vascular Disease)); the applicable result needs member context.

HCC Category Mapping
These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT review for I72.2
For I72.2, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

What This Code Means
I72.2 is the ICD-10-CM diagnosis code for aneurysm of renal artery. A weakened, bulging section of the artery that supplies blood to the kidney, which requires monitoring to prevent rupture. I72.2 sits in the ICD-10-CM chapter for diseases of the circulatory system (i00-i99), within the section covering diseases of arteries, arterioles and capillaries (i70-i79).
I72.2 has no mapping under the current CMS-HCC V28 community payment model. I72.2 has a separate mapping under the CMS-HCC ESRD model (HCC 108 (Vascular Disease)); the applicable result needs member context. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.
Document whether the aneurysm is ruptured or non-ruptured, as this affects code selection.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for I72.2 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
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
Commonly Confused Codes
- •I72.8: Aneurysm of other specified arteries: not appropriate for renal artery, which has its own specific code
- •I72.3: Aneurysm of iliac artery: different vascular territory
- •I77.3: Arterial fibromuscular dysplasia: may coexist but is a different diagnosis
- •N28.0: Ischemia and infarction of kidney: renal ischemia without aneurysm
