| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I77.810 | Thoracic aortic ectasia | Use when the aortic root is dilated but does not meet the criteria for an aneurysm. |
|
| I71.21 | Aneurysm of ascending aorta without rupture | Use when the aortic root or ascending aorta is described as an aneurysm. |

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Dilated Aortic Root to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I77.810.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Could result in coding audits and compliance issues., Financial: Affects reimbursement due to incorrect DRG assignment.
Mitigation Strategy
Always document the specific location of the aortic dilation., Use standardized templates to ensure completeness.
Impact
Reimbursement: Incorrect coding can lead to improper DRG assignment., Compliance: May result in audit issues if documentation does not support the code used., Data Quality: Affects the accuracy of clinical data and patient records.
Mitigation Strategy
Verify the documented size and terminology used by the provider.
Impact
Using aneurysm codes without supporting documentation.
Mitigation Strategy
Ensure all documentation includes specific measurements and terminology.
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.
