Heart Failure codes including systolic, diastolic, and combined heart failure
These codes cover the primary types of heart failure, which are essential for accurate diagnosis and treatment documentation.
Hypertensive heart disease with heart failure
These codes are used when heart failure is due to hypertensive heart disease, affecting sequencing and reimbursement.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I50.21 | Acute systolic (congestive) heart failure | Use when acute symptoms of systolic heart failure are documented with an EF ≤40%. |
|
| I50.31 | Acute diastolic (congestive) heart failure | Use when acute diastolic dysfunction is documented with EF >50%. |

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 heart failure
Decision Criteria
clinical Criteria
- Presence of acute symptoms and EF ≤40%
Applicable To
- Acute heart failure with reduced ejection fraction (HFrEF)
Excludes
- Chronic systolic heart failure (I50.22)
Clinical Validation Requirements
- Ejection fraction ≤40%
- Symptoms such as orthopnea or edema
Code-Specific Risks
- Incorrectly coding chronic conditions as acute
Coding Notes
- Ensure documentation specifies 'acute' and provides EF value.
I50.31 - Acute diastolic (congestive) heart failure
Use when acute diastolic dysfunction is documented with EF >50%.
Applicable To
- Acute heart failure with preserved ejection fraction (HFpEF)
Excludes
- Chronic diastolic heart failure (I50.32)
Clinical Validation Requirements
- Ejection fraction >50%
- Elevated BNP levels
Coding Notes
Document EF and specify 'acute' in the clinical notes.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Heart Failure to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.21.
Impact
Clinical: Leads to inappropriate treatment plans., Regulatory: Non-compliance with ICD-10 coding standards., Financial: Potential for denied claims or reduced reimbursement.
Mitigation Strategy
Always specify systolic or diastolic in documentation., Educate providers on the importance of detailed documentation.
Impact
Reimbursement: May lead to reduced reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases the accuracy of clinical data.
Mitigation Strategy
Always document and code the specific type (systolic, diastolic, or combined) and acuity (acute, chronic).
Impact
High risk of audit if unspecified codes are used when specific documentation is available.
Mitigation Strategy
Implement regular documentation audits and provider education.
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.
