| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I77.810 | Thoracic aortic ectasia | Use when imaging confirms thoracic aortic dilation ≥4 cm. |
|
| I77.811 | Abdominal aortic ectasia | Use when imaging confirms abdominal aortic dilation ≥3 cm. |
|
| I77.812 | Thoracoabdominal aortic ectasia | Use when imaging confirms thoracoabdominal aortic dilation. |
|
| I77.819 | Aortic ectasia, unspecified | Use when the site of aortic ectasia is not specified. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

- Measurement ≥4 cm
Code-Specific Risks
- Confusion with aneurysm codes
Coding Notes
- Ensure documentation specifies thoracic location and diameter.
I77.811 - Abdominal aortic ectasia
Use when imaging confirms abdominal aortic dilation ≥3 cm.
Applicable To
- Abdominal aortic dilation
Excludes
- Abdominal aortic aneurysm (I71.4)
Clinical Validation Requirements
- Imaging confirming abdominal location
- Measurement ≥3 cm
Coding Notes
Ensure documentation specifies abdominal location and diameter.
I77.812 - Thoracoabdominal aortic ectasia
Use when imaging confirms thoracoabdominal aortic dilation.
Applicable To
- Thoracoabdominal aortic dilation
Excludes
- Thoracoabdominal aortic aneurysm (I71.6)
Clinical Validation Requirements
- Imaging confirming thoracoabdominal location
- Measurement criteria as per thoracic and abdominal
Coding Notes
Ensure documentation specifies thoracoabdominal location.
I77.819 - Aortic ectasia, unspecified
Use when the site of aortic ectasia is not specified.
Applicable To
- Unspecified aortic dilation
Excludes
- Aortic aneurysm, unspecified (I71.9)
Clinical Validation Requirements
- Explicit statement: 'Site not specified'
- Exclusion of dissection/rupture
Coding Notes
Encourage specificity in documentation to avoid using unspecified codes.
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.
Thoracic aortic aneurysm
I71.2Abdominal aortic aneurysm
I71.4Thoracoabdominal aortic aneurysm
I71.6Aortic aneurysm, unspecified
I71.9Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Aortic Ectasia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I77.810.
Impact
Clinical: Inaccurate clinical assessment., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.
Mitigation Strategy
Use structured templates., Ensure imaging reports are included.
Impact
Reimbursement: Incorrect DRG assignment leading to reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure diameter criteria for aneurysms are met before using aneurysm codes.
Impact
Frequent use of unspecified codes without justification.
Mitigation Strategy
Encourage detailed documentation specifying site and diameter.
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.
