I50.2-I50.23Primary Range
Heart failure codes including chronic systolic heart failure
This range includes codes for chronic systolic heart failure, which is synonymous with HFrEF.
Hypertensive heart disease with heart failure
These codes are used when hypertension is the underlying cause of heart failure.
Chronic ischemic heart disease
These codes are relevant when coronary artery disease is the underlying cause of heart failure.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I50.22 | Chronic systolic (congestive) heart failure | Use when the patient has chronic heart failure with LVEF ≤40% and symptoms are documented. |
|
| I50.23 | Acute on chronic systolic (congestive) heart failure | Use when there is an acute exacerbation of chronic systolic 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 chronic hfref
Decision Criteria
clinical Criteria
- LVEF ≤40% confirmed by echocardiogram
documentation Criteria
- Explicit mention of 'chronic systolic heart failure' or 'HFrEF'
Applicable To
- Chronic heart failure with reduced ejection fraction (HFrEF)
Excludes
- Acute heart failure (I50.21)
Clinical Validation Requirements
- LVEF ≤40%
- Documentation of chronicity
- Symptoms such as dyspnea, edema
Code-Specific Risks
- Confusion with HFpEF if LVEF is not documented
- Misclassification if chronicity is not specified
Coding Notes
- Ensure documentation specifies 'chronic' and includes LVEF to avoid coding errors.
I50.23 - Acute on chronic systolic (congestive) heart failure
Use when there is an acute exacerbation of chronic systolic heart failure.
Applicable To
- Acute exacerbation of chronic systolic heart failure
Excludes
- Chronic heart failure without acute exacerbation (I50.22)
Clinical Validation Requirements
- LVEF ≤40%
- Documentation of acute exacerbation symptoms
Coding Notes
Ensure acute symptoms are clearly documented to justify the use of this code.
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.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Chronic HFrEF to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.22.
Impact
Clinical: Leads to misclassification of heart failure type., Regulatory: Increases risk of audit discrepancies., Financial: Potential loss of reimbursement due to incorrect coding.
Mitigation Strategy
Standardize LVEF documentation in all heart failure cases, Educate providers on the importance of LVEF
Impact
Reimbursement: Incorrect coding can lead to improper DRG assignment., Compliance: May result in compliance issues during audits., Data Quality: Affects the accuracy of clinical data and research.
Mitigation Strategy
Ensure LVEF is documented to distinguish between reduced and preserved ejection fraction.
Impact
Reimbursement: Affects DRG and RAF score calculations., Compliance: Leads to potential audit flags., Data Quality: Impacts longitudinal patient data tracking.
Mitigation Strategy
Always document whether the heart failure is acute, chronic, or acute on chronic.
Impact
Failure to document LVEF can lead to incorrect coding and audit issues.
Mitigation Strategy
Implement mandatory LVEF documentation protocols.
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.
