| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I50.30 | Unspecified diastolic heart failure | Use when diastolic heart failure is documented without specification of acuity. |
|
| I50.31 | Acute diastolic heart failure | Use when acute exacerbation of diastolic heart failure is documented. |
|
| I50.32 | Chronic diastolic heart failure | Use for chronic diastolic heart failure without acute exacerbation. |
|
| I50.33 | Acute on chronic diastolic heart failure | Use when acute exacerbation occurs on a chronic diastolic heart failure background. |

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 diastolic heart failure
Decision Criteria
clinical Criteria
- EF ≥50% with symptoms of heart failure.
Applicable To
- Diastolic heart failure NOS
Clinical Validation Requirements
- Documentation of heart failure with preserved ejection fraction (EF ≥50%)
Code-Specific Risks
- Risk of under-coding if acuity is not specified.
Coding Notes
- Ensure EF is documented to avoid unspecified coding.
I50.31 - Acute diastolic heart failure
Use when acute exacerbation of diastolic heart failure is documented.
Applicable To
- Acute heart failure with preserved ejection fraction
Excludes
- Chronic diastolic heart failure (I50.32)
Clinical Validation Requirements
- Acute symptoms with EF ≥50%, requiring immediate treatment.
Coding Notes
Document acute symptoms and treatment interventions.
I50.32 - Chronic diastolic heart failure
Use for chronic diastolic heart failure without acute exacerbation.
Applicable To
- Chronic heart failure with preserved ejection fraction
Excludes
- Acute diastolic heart failure (I50.31)
Clinical Validation Requirements
- Chronic symptoms with EF ≥50%.
Coding Notes
Document chronic symptoms and management plan.
I50.33 - Acute on chronic diastolic heart failure
Use when acute exacerbation occurs on a chronic diastolic heart failure background.
Applicable To
- Acute exacerbation of chronic heart failure with preserved ejection fraction
Excludes
- Chronic diastolic heart failure (I50.32)
Clinical Validation Requirements
- Acute exacerbation on a background of chronic symptoms with EF ≥50%.
Coding Notes
Document both acute exacerbation and chronic management.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Diastolic Heart Failure to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.30.
Impact
Clinical: Leads to misclassification of heart failure type., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Ensure EF is recorded in all heart failure diagnoses.
Impact
Reimbursement: Potential for reduced reimbursement if coded as unspecified., Compliance: Risk of non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Ensure EF is documented as ≥50% to support diastolic heart failure coding.
Impact
Reimbursement: Incorrect DRG assignment may affect payment., Compliance: Non-compliance with coding standards., Data Quality: Misrepresents patient condition severity.
Mitigation Strategy
Verify documentation for acute symptoms and treatment before coding as acute.
Impact
Using unspecified codes without supporting documentation.
Mitigation Strategy
Ensure EF and causal factors are documented to support specific coding.
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.
