| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I50.20 | Unspecified systolic (congestive) heart failure | Use when documentation lacks specificity on acuity (acute, chronic, or acute on chronic). |
|
| I50.21 | Acute systolic (congestive) heart failure | Use when acute symptoms and reduced ejection fraction are documented. |
|
| I50.22 | Chronic systolic (congestive) heart failure | Use when chronic symptoms and reduced ejection fraction are documented. |
|
| I50.23 | Acute on chronic systolic (congestive) heart failure | Use when both chronic heart failure and acute exacerbation are documented. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Decision Criteria
documentation Criteria
- Lack of acuity specification in documentation.
Applicable To
- Systolic heart failure NOS
Excludes
- Diastolic heart failure (I50.3-)
Clinical Validation Requirements
- Documentation of systolic heart failure without specification of acuity
Code-Specific Risks
- Potential for reduced reimbursement due to lack of specificity.
Coding Notes
- Ensure documentation specifies acuity to avoid using unspecified codes.
I50.21 - Acute systolic (congestive) heart failure
Use when acute symptoms and reduced ejection fraction are documented.
Applicable To
- Acute heart failure with reduced ejection fraction
Excludes
- Chronic systolic heart failure (I50.22)
Clinical Validation Requirements
- LVEF ≤40%
- Acute onset of symptoms such as dyspnea or orthopnea
Coding Notes
Document acute symptoms and LVEF to support code use.
I50.22 - Chronic systolic (congestive) heart failure
Use when chronic symptoms and reduced ejection fraction are documented.
Applicable To
- Chronic heart failure with reduced ejection fraction
Excludes
- Acute systolic heart failure (I50.21)
Clinical Validation Requirements
- LVEF ≤40%
- Stable symptoms managed with medication
Coding Notes
Document chronic management and LVEF to support code use.
I50.23 - Acute on chronic systolic (congestive) heart failure
Use when both chronic heart failure and acute exacerbation are documented.
Applicable To
- Acute exacerbation of chronic heart failure with reduced ejection fraction
Excludes
- Chronic systolic heart failure without acute exacerbation (I50.22)
Clinical Validation Requirements
- LVEF ≤40%
- Documentation of both chronic baseline and acute exacerbation
Coding Notes
Document both chronic and acute components to support code use.
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.
Unspecified diastolic (congestive) heart failure
I50.30Chronic systolic (congestive) heart failure
I50.22Acute systolic (congestive) heart failure
I50.21Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Heart Failure with Reduced Ejection Fraction to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.20.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Ensure echocardiogram results are included in the patient's record.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces accuracy of clinical data.
Mitigation Strategy
Ensure documentation specifies acuity to use the most specific code.
Impact
Failure to document acuity can lead to audit findings.
Mitigation Strategy
Educate providers on the importance of documenting acuity.
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.
