| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I77.810 | Thoracic aortic ectasia | Use when aortic root is dilated but does not meet criteria for aneurysm. |
|
| I71.21 | Aneurysm of ascending aorta, without rupture | Use when aortic root meets criteria for aneurysm. |
|
| Q87.4 | Marfan syndrome | Use when Marfan syndrome is confirmed and affects the aortic root. |

Decision Criteria
clinical Criteria
- Aortic root diameter >4.0 cm in males or >3.8 cm in females
Clinical Validation Requirements
- Imaging studies showing aortic root diameter >4.0 cm in males or >3.8 cm in females
Code-Specific Risks
- Misclassification if aneurysm criteria are met
Coding Notes
- Ensure documentation specifies aortic root measurements and absence of aneurysm.
I71.21 - Aneurysm of ascending aorta, without rupture
Use when aortic root meets criteria for aneurysm.
Applicable To
- Aortic root aneurysm
Excludes
- Ruptured aortic aneurysm (I71.1)
Clinical Validation Requirements
- Imaging showing aortic root diameter ≥5.0 cm or rapid progression
Coding Notes
Document specific measurements and progression to justify aneurysm classification.
Q87.4 - Marfan syndrome
Use when Marfan syndrome is confirmed and affects the aortic root.
Applicable To
- Marfan syndrome with aortic root involvement
Excludes
- Other connective tissue disorders (Q87.8)
Clinical Validation Requirements
- Genetic testing confirming Marfan syndrome
Coding Notes
Ensure genetic confirmation is documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Q87.8Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Dilation of 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: Non-compliance with documentation standards., Financial: Potential for denied claims due to lack of specificity.
Mitigation Strategy
Use templates for consistent documentation., Ensure all imaging and measurements are included.
Impact
Reimbursement: May lead to lower reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces the accuracy of clinical data.
Mitigation Strategy
Always specify the aortic segment and confirm presence or absence of aneurysm.
Impact
Risk of audits due to use of unspecified codes.
Mitigation Strategy
Ensure detailed documentation and 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.
