| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I71.43 | Infrarenal abdominal aortic aneurysm, without rupture | Use when imaging confirms an infrarenal AAA without rupture. |
|
| I71.33 | Infrarenal abdominal aortic aneurysm, ruptured | Use when imaging and clinical findings confirm rupture. |

Primary ICD-10-CM Codes for infrarenal abdominal aortic aneurysm
Decision Criteria
clinical Criteria
- Imaging confirms infrarenal location without rupture.
Applicable To
- Asymptomatic infrarenal AAA
- Stable infrarenal AAA
Excludes
- Ruptured infrarenal AAA (I71.33)
Clinical Validation Requirements
- CTA or MRI showing aneurysm distal to renal arteries
- Diameter ≥3.0 cm
- No evidence of rupture
Code-Specific Risks
- Misclassification if rupture status is not documented
Coding Notes
- Ensure documentation specifies 'infrarenal' and 'without rupture'.
I71.33 - Infrarenal abdominal aortic aneurysm, ruptured
Use when imaging and clinical findings confirm rupture.
Applicable To
- Ruptured infrarenal AAA
Excludes
- Non-ruptured infrarenal AAA (I71.43)
Clinical Validation Requirements
- CTA showing peri-aortic hematoma or active extravasation
- Clinical signs of rupture such as hypotension
Coding Notes
Ensure rupture is documented in both imaging and clinical notes.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Infrarenal Abdominal Aortic Aneurysm to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I71.43.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Increases risk of audit discrepancies., Financial: Potential loss of reimbursement for higher DRG.
Mitigation Strategy
Ensure imaging and clinical notes are reviewed for rupture status.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Increases risk of audit failures., Data Quality: Reduces accuracy of health records.
Mitigation Strategy
Ensure documentation specifies the exact location and rupture status.
Impact
Inadequate documentation of rupture status can lead to audit issues.
Mitigation Strategy
Ensure thorough documentation in imaging and clinical notes.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
