| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I35.0 | Nonrheumatic aortic stenosis | Use when calcification causes hemodynamically significant stenosis. |
|
| Q23.81 | Congenital bicuspid aortic valve | Use when a congenital bicuspid valve is present, especially if calcification leads to stenosis. |

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

Primary ICD-10-CM Codes for calcification of aortic valve
Decision Criteria
clinical Criteria
- Presence of severe stenosis with calcification.
documentation Criteria
- Documented mean gradient and AVA.
Applicable To
- Aortic stenosis due to calcification
Excludes
- Rheumatic aortic stenosis (I06.0)
Clinical Validation Requirements
- Mean gradient ≥40 mmHg
- Aortic valve area (AVA) ≤1.0 cm²
- CT calcium score ≥1,200 AU (women) or ≥2,000 AU (men)
Code-Specific Risks
- Misclassification if stenosis is not hemodynamically significant.
Coding Notes
- Ensure documentation specifies the presence of stenosis and its severity.
Q23.81 - Congenital bicuspid aortic valve
Use when a congenital bicuspid valve is present, especially if calcification leads to stenosis.
Applicable To
- Bicuspid aortic valve
Excludes
- Tricuspid aortic valve
Clinical Validation Requirements
- Echocardiographic evidence of bicuspid valve morphology
Coding Notes
Document congenital nature of the valve.
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 Calcification of Aortic Valve to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I35.0.
Impact
Clinical: Misrepresentation of patient's condition., Regulatory: Potential audit risk., Financial: Incorrect billing and reimbursement.
Mitigation Strategy
Always document valve morphology.
Impact
Reimbursement: Incorrect DRG assignment leading to potential overpayment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation specifies hemodynamic significance.
Impact
Inadequate documentation of stenosis severity.
Mitigation Strategy
Ensure all hemodynamic data is included in reports.
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.
