| Z95.2 | Presence of aortic graft | Use alongside Z86.79 when a graft is present post-AAA repair. |
|
| I77.81 | Aortic ectasia | Use for residual dilatation post-repair that does not qualify as an aneurysm. |

Z95.2Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting History of Abdominal Aortic Aneurysm to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z86.79.
Impact
Clinical: Inaccurate patient history, Regulatory: Non-compliance with documentation standards, Financial: Potential claim denials
Mitigation Strategy
Review surgical history, Ensure graft status is documented
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate patient records.
Mitigation Strategy
Use Z86.79 for history of AAA without current aneurysm.
Impact
Inadequate documentation of surgical history and current status.
Mitigation Strategy
Ensure comprehensive documentation of surgical and imaging history.
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.
