| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I06.0 | Rheumatic aortic stenosis | Use when aortic stenosis is due to rheumatic fever. |
|
| I35.0 | Nonrheumatic aortic stenosis | Use for nonrheumatic causes of aortic stenosis. |
|
| I08.0 | Rheumatic disorders of both mitral and aortic valves | Use when both mitral and aortic valves are affected by rheumatic disease. |
|
| Q23.1 | Congenital bicuspid aortic valve | Use for congenital bicuspid aortic valve. |

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

Z95.2Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Aortic Valve Stenosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I06.0.
Impact
Clinical: Inadequate treatment planning., Regulatory: Potential for coding audits., Financial: Incorrect reimbursement levels.
Mitigation Strategy
Document AVA and gradients., Ensure echocardiogram results are included.
Impact
Reimbursement: Incorrect DRG assignment may affect payment., Compliance: Potential for audit discrepancies., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Verify rheumatic history before coding.
Impact
Misclassification of rheumatic vs. nonrheumatic stenosis.
Mitigation Strategy
Verify patient history and echocardiogram findings.
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.
