| 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 ≥1.5 times normal. |
|
| I77.810 | Thoracic aortic ectasia | Use when imaging shows dilation of the thoracic aorta without meeting aneurysm criteria. |

- Diameter <1.5x normal size
Coding Notes
Document exact measurements and imaging method.
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 Dilation of Ascending Aorta to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I71.21.
Impact
Clinical: Inaccurate diagnosis and treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential denial of claims due to insufficient documentation.
Mitigation Strategy
Ensure imaging reports are included in the patient's record., Train staff on documentation requirements.
Impact
Reimbursement: Potentially lower reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Decreased accuracy in clinical data.
Mitigation Strategy
Use specific codes like I71.21 or I77.810 based on imaging and documentation.
Impact
Using codes like I77.89 when specific codes are applicable.
Mitigation Strategy
Ensure documentation supports the use of specific codes.
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.
