What is ICD-10 code I71.30?

I71.30 is the ICD-10-CM diagnosis code for Abdominal aortic aneurysm, ruptured, unspecified. A ruptured weakened, bulging area in the abdominal aorta (the main artery in the abdomen) where the specific location is not specified. It belongs to the ICD-10-CM chapter for diseases of the circulatory system (i00-i99). I71.30 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. I71.30 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. I71.30 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. I71.30 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Which HCC does I71.30 map to under V28?

I71.30 maps to CMS-HCC V28 264 (Vascular Disease with Complications). The category number and label come from the CMS-HCC V28 model file for payment year 2026.

What does I71.30 pay in RAF?

I71.30 carries a community, non-dual, aged (CNA) RAF weight of 0.455 under CMS-HCC V28 for payment year 2026. The weight comes from the CMS V28 relative-factor file, not a hand-typed table.

What is the V28 vs V24 difference for I71.30?

CMS phased in the V28 risk adjustment model over payment years 2024 (33%), 2025 (67%), and 2026 (100%), replacing V24. V28 consolidates HCC categories, removes some lower-acuity conditions, and recalibrates RAF weights across the entire model. For I71.30, V28 maps to Vascular Disease with Complications at RAF 0.455 while V24 mapped to Vascular Disease with Complications at RAF 0.383. Both models can still appear in legacy data and in payer-specific lookback periods.

What documentation supports I71.30?

This is an unspecified code; use more specific codes (I71.31, I71.32, I71.33) when the exact location is documented Ruptured AAA is a life-threatening emergency requiring immediate documentation of location if available Because I71.30 maps to a payment HCC, the documentation must also satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's risk adjustment score. See the MEAT criteria checklist at /meat-criteria for what Monitor, Evaluate, Assess, or Treat looks like in a note. MEAT is generic documentation evidence, not a payer-specific rule.

Buddy Documentation Tip

HCC Buddy guidance

Ruptured abdominal aortic aneurysm documented — anatomical location: unspecified

Rupture confirmed by imaging (CT showing retroperitoneal hemorrhage, free fluid) or intraoperative findings

Aneurysm size at time of rupture documented

Hemodynamic status at presentation (hypotension, shock, resuscitation requirements)

Hemodynamic status at presentation (hypotension, shock, resuscitation requirements)

Audit Caution

HCC Buddy guidance

Coding non-ruptured abdominal aortic aneurysm (I71.40-I71.41) when rupture has occurred — this severely undercodes the severity and misses the higher HCC

Failing to specify the relationship to the renal arteries (infrarenal, juxtarenal, pararenal) when documented — this determines surgical approach and code specificity

Confusing abdominal aortic aneurysm rupture with aortic dissection — both are emergencies but represent different pathologies with different code ranges

Not capturing postoperative complications that warrant additional diagnosis codes (acute kidney injury, bowel ischemia)

Common Mistakes

HCC Buddy guidance

I71.40-I71.41 — Abdominal aortic aneurysm WITHOUT rupture (non-ruptured — dramatically different acuity and HCC mapping)

I71.10-I71.13 — Thoracic aortic aneurysm, ruptured (different anatomical location — thoracic vs. abdominal)

I71.02 — Dissection of abdominal aorta (dissection is intimal tear, not aneurysm rupture — different pathology)

I71.5/I71.6 — Thoracoabdominal aortic aneurysm codes (use these when the aneurysm extends across both thoracic and abdominal segments)

Is I71.30 an HCC code?

Yes. I71.30 (Abdominal aortic aneurysm, ruptured, unspecified) maps to Vascular Disease with Complications under the CMS-HCC V28 risk adjustment model (and Vascular Disease with Complications under V24), with a community non-dual aged RAF of 0.455. It is billable for payment year 2026.

Coder answer: I71.30 is billable and maps to V28 HCC 264, Vascular Disease with Complications. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

Each model's RAF is its CMS base weight for that model's standard population, so 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 segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for I71.30

For I71.30 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.

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

Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed I71.30 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

I71.30 is the ICD-10-CM diagnosis code for abdominal aortic aneurysm, ruptured, unspecified. A ruptured weakened, bulging area in the abdominal aorta (the main artery in the abdomen) where the specific location is not specified. I71.30 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).

Under the CMS-HCC V28 risk adjustment model, I71.30 maps to Vascular Disease with Complications (HCC 264) with a community, non-dual, aged base RAF weight of 0.455. Under the older V24 model, I71.30 mapped to the same category but with a base RAF weight of 0.383, V28 recalibrated weights across the entire model. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.

This is an unspecified code; use more specific codes (I71.31, I71.32, I71.33) when the exact location is documented. Because I71.30 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for I71.30 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•This is an unspecified code; use more specific codes (I71.31, I71.32, I71.33) when the exact location is documented
•Ruptured AAA is a life-threatening emergency requiring immediate documentation of location if available

Clinical Significance

Ruptured abdominal aortic aneurysm (unspecified) is a catastrophic vascular emergency with mortality rates of 80-90% overall, including prehospital deaths. Even with emergent surgical repair, operative mortality remains 40-50%. This condition causes massive retroperitoneal or intraperitoneal hemorrhage and hemodynamic collapse. Survivors face prolonged intensive care stays and significant postoperative complications, making this among the highest-acuity vascular diagnoses for risk adjustment.

Documentation Requirements

✓Ruptured abdominal aortic aneurysm documented — anatomical location: unspecified
✓Rupture confirmed by imaging (CT showing retroperitoneal hemorrhage, free fluid) or intraoperative findings
✓Aneurysm size at time of rupture documented
✓Hemodynamic status at presentation (hypotension, shock, resuscitation requirements)
✓Relationship to renal arteries documented (infrarenal, juxtarenal, pararenal, suprarenal) — critical for surgical planning and code specificity
✓Surgical intervention type (open repair vs. endovascular aortic repair) and findings
✓Postoperative complications documented (acute kidney injury, bowel ischemia, abdominal compartment syndrome)

Commonly Confused Codes

•I71.40-I71.41: Abdominal aortic aneurysm WITHOUT rupture (non-ruptured: dramatically different acuity and HCC mapping)
•I71.10-I71.13: Thoracic aortic aneurysm, ruptured (different anatomical location: thoracic vs. abdominal)
•I71.02: Dissection of abdominal aorta (dissection is intimal tear, not aneurysm rupture: different pathology)
•I71.5/I71.6: Thoracoabdominal aortic aneurysm codes (use these when the aneurysm extends across both thoracic and abdominal segments)
