| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I71.40 | Abdominal aortic aneurysm, without rupture, unspecified | Use when the specific site of the aneurysm is not documented. |
|
| I71.43 | Infrarenal abdominal aortic aneurysm, without rupture | Use when the aneurysm is located below the renal arteries and is not ruptured. |

Decision Criteria
documentation Criteria
- Lack of specific site documentation
Applicable To
- Unspecified site of abdominal aortic aneurysm without rupture
Excludes
- Ruptured abdominal aortic aneurysm (I71.3-)
Clinical Validation Requirements
- Imaging showing aortic diameter ≥3.0 cm
- No evidence of rupture
Code-Specific Risks
- Potential for undercoding if specific site is known but not documented.
Coding Notes
- Ensure documentation specifies rupture status to avoid miscoding.
I71.43 - Infrarenal abdominal aortic aneurysm, without rupture
Use when the aneurysm is located below the renal arteries and is not ruptured.
Applicable To
- Infrarenal site of abdominal aortic aneurysm without rupture
Excludes
- Ruptured infrarenal abdominal aortic aneurysm (I71.3-)
Clinical Validation Requirements
- Imaging showing infrarenal location
- Aortic diameter ≥3.0 cm
- No evidence of rupture
Coding Notes
Document specific location and size for accurate coding.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Abdominal Aortic Aneurysm to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I71.40.
Impact
Clinical: Inaccurate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Incorrect reimbursement.
Mitigation Strategy
Always confirm rupture status with imaging., Include rupture status in all clinical documentation.
Impact
Reimbursement: Potential loss of revenue due to incorrect DRG assignment., Compliance: Non-compliance with coding guidelines., Data Quality: Decreased accuracy in clinical data reporting.
Mitigation Strategy
Query provider for specific site documentation if not initially provided.
Impact
High risk of audit if specific site is documented but unspecified code is used.
Mitigation Strategy
Ensure all documentation includes specific site details.
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.
