I50.3-I50.33Primary Range
Heart failure with preserved ejection fraction
This range covers heart failure conditions where the ejection fraction is preserved, which is typical in diastolic dysfunction.
Other ill-defined heart diseases
Used for cases of diastolic dysfunction without heart failure symptoms.
Hypertensive heart disease with heart failure
Applicable when hypertension is the underlying cause of heart failure.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I50.31 | Acute diastolic heart failure | Use when acute symptoms of heart failure are present with preserved ejection fraction. |
|
| I50.32 | Chronic diastolic heart failure | Use for chronic heart failure with preserved ejection fraction. |
|
| I51.89 | Other ill-defined heart diseases | Use for diastolic dysfunction without heart failure symptoms. |

Use for diastolic dysfunction without heart failure symptoms.
Applicable To
- Asymptomatic diastolic dysfunction
Excludes
- Heart failure with preserved ejection fraction (I50.3-)
Clinical Validation Requirements
- Echocardiogram showing diastolic dysfunction without symptoms
Coding Notes
Ensure no heart failure symptoms are documented.

I11.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Left Ventricular Diastolic Dysfunction to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.31.
Impact
Clinical: Inaccurate diagnosis of heart failure type., Regulatory: Non-compliance with coding standards., Financial: Potential loss of reimbursement.
Mitigation Strategy
Ensure all heart failure symptoms are documented., Use standardized templates for heart failure documentation.
Impact
Reimbursement: May result in lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure ejection fraction and heart failure type are documented.
Impact
Using unspecified codes when specific ejection fraction data is available.
Mitigation Strategy
Implement EHR alerts for missing ejection fraction 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.
