| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I50.22 | Chronic systolic (congestive) heart failure | Use when documentation specifies chronic systolic heart failure with EF ≤40%. |
|
| I50.32 | Chronic diastolic (congestive) heart failure | Use when documentation specifies chronic diastolic heart failure with EF ≥50%. |
|
| I50.42 | Chronic combined systolic and diastolic heart failure | Use when both systolic and diastolic dysfunction 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.

Primary ICD-10-CM Codes for chronic heart failure
Decision Criteria
clinical Criteria
- EF ≤40% with chronic symptoms
documentation Criteria
- Explicit mention of 'chronic systolic heart failure'
Applicable To
- HFrEF
- Heart failure with reduced ejection fraction
Excludes
- Acute systolic heart failure (I50.21)
Clinical Validation Requirements
- Ejection fraction ≤40%
- S3 gallop
- Pulmonary edema on chest X-ray
Code-Specific Risks
- Ensure EF documentation is present to avoid misclassification.
Coding Notes
- Ensure to document EF and specify 'chronic' to differentiate from acute conditions.
I50.32 - Chronic diastolic (congestive) heart failure
Use when documentation specifies chronic diastolic heart failure with EF ≥50%.
Applicable To
- HFpEF
- Heart failure with preserved ejection fraction
Excludes
- Acute diastolic heart failure (I50.31)
Clinical Validation Requirements
- Ejection fraction ≥50%
- E/E' ratio >15 on echocardiogram
- Left atrial enlargement
Coding Notes
Document diastolic dysfunction and EF to ensure accurate coding.
I50.42 - Chronic combined systolic and diastolic heart failure
Use when both systolic and diastolic dysfunction are documented.
Applicable To
- Combined heart failure
Excludes
- Acute combined heart failure (I50.41)
Clinical Validation Requirements
- Documentation of both systolic and diastolic dysfunction
- Ejection fraction and diastolic parameters
Coding Notes
Document both systolic and diastolic dysfunction clearly.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Chronic Heart Failure 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 inappropriate treatment plans., Regulatory: May result in non-compliance with coding standards., Financial: Can cause claim denials or reduced reimbursement.
Mitigation Strategy
Ensure EF is documented in every heart failure diagnosis., Train staff on the importance of EF in coding.
Impact
Reimbursement: Incorrect coding can lead to lower reimbursement rates., Compliance: Non-specific coding may not meet compliance standards., Data Quality: Ambiguous data affects clinical decision-making and reporting.
Mitigation Strategy
Always specify whether the heart failure is systolic, diastolic, or combined.
Impact
Reimbursement: May result in denied claims or reduced payments., Compliance: Fails to meet coding guidelines for active conditions., Data Quality: Leads to inaccurate clinical data and reporting.
Mitigation Strategy
Ensure active management or treatment is documented before coding.
Impact
Coding heart failure without EF can lead to audits and claim denials.
Mitigation Strategy
Implement mandatory EF documentation policies.
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.
