| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I35.0 | Nonrheumatic aortic (valve) stenosis | Use when there is documented nonrheumatic calcific stenosis of the aortic valve. |
|
| Q23.81 | Congenital bicuspid aortic valve | Use when there is a congenital bicuspid aortic valve, especially if calcified. |

Essential facts and insights about Calcified Aortic Valve
Primary ICD-10-CM Codes for calcified aortic valve
Decision Criteria
clinical Criteria
- Echocardiogram findings consistent with severe stenosis
documentation Criteria
- Documented CT calcium score supporting severity
Applicable To
- Calcific aortic stenosis
Excludes
- Rheumatic aortic stenosis (I06.0)
Clinical Validation Requirements
- Echocardiogram showing aortic valve area ≤1.0 cm²
- Mean gradient ≥40 mmHg
- CT calcium score ≥2000 AU (men) or ≥1300 AU (women)
Code-Specific Risks
- Misclassification as rheumatic stenosis
- Overcoding mild calcification without stenosis
Coding Notes
- Ensure documentation specifies nonrheumatic origin and provides imaging evidence.
Q23.81 - Congenital bicuspid aortic valve
Use when there is a congenital bicuspid aortic valve, especially if calcified.
Applicable To
- Bicuspid aortic valve with calcification
Excludes
- Acquired aortic stenosis (I35.0)
Clinical Validation Requirements
- Echocardiogram showing bicuspid morphology
- Documentation of congenital origin
Coding Notes
Ensure congenital nature is clearly documented.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Calcified 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: Mismanagement of congenital conditions., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims due to incorrect coding.
Mitigation Strategy
Use templates that prompt for congenital details, Educate providers on documentation requirements
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient care.
Mitigation Strategy
Ensure documentation specifies the location of stenosis.
Impact
Risk of audits due to incorrect differentiation between congenital and acquired stenosis.
Mitigation Strategy
Ensure thorough documentation of valve morphology and calcification.
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.
