Decision Criteria
clinical Criteria
- Echocardiogram confirms moderate stenosis criteria.
documentation Criteria
- Documentation specifies nonrheumatic etiology.
Applicable To
- Moderate aortic stenosis
Excludes
- Rheumatic aortic stenosis (I06.0)
Clinical Validation Requirements
- Echocardiogram showing Vmax 3.0–3.9 m/s
- Mean gradient 20–39 mmHg
- Aortic valve area (AVA) >1.0 cm²
Code-Specific Risks
- Incorrectly coding as unspecified (I35.9) when severity is documented.
Coding Notes
- Ensure documentation specifies 'nonrheumatic' and includes echocardiographic values.
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.

I06.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Moderate Aortic Stenosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I35.0.
Impact
Clinical: May lead to incorrect severity classification., Regulatory: Non-compliance with documentation standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Ensure echocardiogram results are included in the patient's record.
Impact
Reimbursement: Incorrect coding may affect DRG assignment and reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation includes specific echocardiographic values for moderate stenosis.
Impact
Inadequate documentation of echocardiographic criteria for moderate AS.
Mitigation Strategy
Implement checklist for required echocardiographic values in documentation.
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.
