| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I71.21 | Aneurysm of ascending aorta without rupture | Use when imaging confirms an aneurysm of the ascending aorta with a diameter ≥3.5 cm and no rupture. |
|
| I77.810 | Aortic ectasia | Use for mild dilation of the ascending aorta with diameter <3.5 cm. |

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Ascending Aorta Dilation to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I71.21.
Impact
Clinical: Potential misdiagnosis or inappropriate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Incorrect billing and reimbursement.
Mitigation Strategy
Educate providers on documentation specificity, Implement checklist for imaging reports
Impact
Reimbursement: Incorrect DRG assignment leading to potential underpayment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Require provider clarification to specify aortic segment.
Impact
Use of unspecified codes for aortic conditions.
Mitigation Strategy
Require detailed imaging reports specifying aortic segment and measurements.
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.
