Code Comparison: When to Use Each Code
Compare key differences between these codes to ensure accurate selection
| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I35.0 | Nonrheumatic aortic stenosis | Use when calcification causes hemodynamically significant stenosis. |
|
| I35.9 | Nonrheumatic aortic valve disorder, unspecified | Use when calcification is present without hemodynamic significance. |

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 aortic valve calcification
Decision Criteria
clinical Criteria
- Presence of severe calcification with hemodynamic impact.
Applicable To
- Calcific aortic stenosis
Excludes
- Rheumatic aortic stenosis (I06.0)
Clinical Validation Requirements
- Peak velocity ≥4 m/s
- Mean gradient ≥40 mmHg
- Aortic valve area (AVA) ≤1.0 cm²
Code-Specific Risks
- Ensure documentation specifies hemodynamic significance to avoid miscoding.
Coding Notes
- Document imaging findings and hemodynamic data to support coding.
I35.9 - Nonrheumatic aortic valve disorder, unspecified
Use when calcification is present without hemodynamic significance.
Applicable To
- Aortic sclerosis
Excludes
- Rheumatic aortic valve disorders (I06.-)
Clinical Validation Requirements
- Documented calcification without significant gradient or AVA reduction.
Coding Notes
Clarify if calcification is incidental or causing stenosis.
Ancillary Codes

Q23.83Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Aortic Valve Calcification to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I35.0.
Impact
Clinical: Inadequate assessment of stenosis severity., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials.
Mitigation Strategy
Include AVA and gradient in all reports.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation includes AVA and gradient measurements.
Impact
Risk of coding errors due to lack of specific documentation.
Mitigation Strategy
Implement thorough documentation practices.
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.
