| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I50.30 | Unspecified diastolic (congestive) heart failure | Use when diastolic dysfunction is explicitly linked to heart failure. |
|
| I51.89 | Other ill-defined heart diseases | Use when diastolic dysfunction is documented without heart failure. |

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 grade 1 diastolic dysfunction
Decision Criteria
clinical Criteria
- Presence of heart failure symptoms and echocardiographic evidence of diastolic dysfunction.
documentation Criteria
- Explicit mention of 'diastolic heart failure' or 'HFpEF'.
Applicable To
- Diastolic heart failure with unspecified acuity
Excludes
- Systolic heart failure
- Combined systolic and diastolic heart failure
Clinical Validation Requirements
- E/A ratio <0.8
- e' velocity <8 cm/s
- Normal LA volume
Code-Specific Risks
- Incorrect use without HF linkage
- Misclassification as systolic HF
Coding Notes
- Ensure documentation explicitly links diastolic dysfunction to heart failure.
I51.89 - Other ill-defined heart diseases
Use when diastolic dysfunction is documented without heart failure.
Applicable To
- Heart disease not otherwise specified
Excludes
- Diastolic heart failure
- Systolic heart failure
Clinical Validation Requirements
- Absence of heart failure symptoms
- Echocardiographic findings without HF linkage
Coding Notes
Ensure no heart failure is documented when using this code.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Encounter for cardiovascular exam
Z00.6Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Grade 1 Diastolic Dysfunction to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.30.
Impact
Clinical: Misrepresentation of patient's condition., Regulatory: Non-compliance with coding standards., Financial: Potential revenue loss due to incorrect coding.
Mitigation Strategy
Educate providers on documentation requirements., Use templates to ensure complete documentation.
Impact
Reimbursement: Incorrect DRG assignment, potential revenue loss., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Query provider to confirm if diastolic dysfunction is causing heart failure.
Impact
Incorrect coding of diastolic dysfunction without heart failure linkage.
Mitigation Strategy
Implement provider education and documentation audits.
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.
