| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I71.21 | Aneurysm of ascending aorta without rupture | Use when imaging confirms an unruptured aneurysm of the ascending aorta. |
|
| I71.11 | Ruptured aneurysm of ascending aorta | Use when there is evidence of rupture in the ascending aorta. |

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

Essential facts and insights about Ascending Thoracic Aneurysm
Primary ICD-10-CM Codes for ascending thoracic aneurysm
Decision Criteria
clinical Criteria
- Imaging confirms aneurysm size and location without rupture.
Applicable To
- Unruptured ascending thoracic aortic aneurysm
Excludes
- Ruptured ascending aortic aneurysm (I71.11)
Clinical Validation Requirements
- CT or MRI showing ascending aorta diameter ≥4.0 cm in men or ≥3.9 cm in women
- Absence of rupture or dissection
Code-Specific Risks
- Incorrectly coding as unspecified thoracic aneurysm (I71.20)
Coding Notes
- Ensure documentation specifies the location and rupture status of the aneurysm.
I71.11 - Ruptured aneurysm of ascending aorta
Use when there is evidence of rupture in the ascending aorta.
Applicable To
- Ruptured ascending thoracic aortic aneurysm
Excludes
- Unruptured ascending aortic aneurysm (I71.21)
Clinical Validation Requirements
- Imaging or surgical findings confirming rupture
- Clinical symptoms such as acute chest pain or shock
Coding Notes
Rupture status must be clearly documented to avoid coding errors.
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 Ascending Thoracic Aneurysm to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I71.21.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with coding standards., Financial: Potential for incorrect billing and reimbursement.
Mitigation Strategy
Ensure imaging reports are reviewed and documented., Use standardized templates for documentation.
Impact
Reimbursement: Incorrect coding can lead to lower reimbursement rates., Compliance: May result in non-compliance with coding standards., Data Quality: Affects the accuracy of clinical data and reporting.
Mitigation Strategy
Ensure documentation specifies the location and rupture status to use I71.21 or I71.11.
Impact
High risk of audit if unspecified codes are used when specific codes are applicable.
Mitigation Strategy
Ensure detailed documentation of aneurysm location and rupture status.
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.
