| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I50.23 | Acute on chronic systolic (congestive) heart failure | Use when documentation specifies acute exacerbation of chronic systolic heart failure with supporting clinical evidence. |
|
| I50.33 | Acute on chronic diastolic (congestive) heart failure | Use when documentation specifies acute exacerbation of chronic diastolic heart failure with supporting clinical evidence. |

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 exacerbation
Decision Criteria
clinical Criteria
- EF <40% with acute symptoms
documentation Criteria
- Explicit mention of acute on chronic systolic heart failure
Applicable To
- Acute exacerbation of chronic systolic heart failure
Excludes
- Diastolic heart failure (I50.3-)
Clinical Validation Requirements
- Ejection Fraction (EF) <40%
- BNP >500 pg/mL
- Symptoms of acute decompensation
Code-Specific Risks
- Incorrectly using unspecified codes when specifics are documented.
Coding Notes
- Ensure documentation specifies systolic vs diastolic and acute vs chronic.
I50.33 - Acute on chronic diastolic (congestive) heart failure
Use when documentation specifies acute exacerbation of chronic diastolic heart failure with supporting clinical evidence.
Applicable To
- Acute exacerbation of chronic diastolic heart failure
Excludes
- Systolic heart failure (I50.2-)
Clinical Validation Requirements
- Ejection Fraction (EF) ≥50%
- NT-proBNP >300 pg/mL
- Diastolic dysfunction on echocardiogram
Coding Notes
Ensure documentation specifies diastolic dysfunction and acute symptoms.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Heart Failure Exacerbation to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.23.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Use templates that prompt for EF and type., Educate providers on documentation standards.
Impact
Reimbursement: Using specific codes can increase reimbursement significantly., Compliance: Ensures compliance with coding guidelines., Data Quality: Improves accuracy of clinical data.
Mitigation Strategy
Query for EF and type of heart failure to use specific codes.
Impact
High risk of audit if unspecified codes are used when specific documentation is available.
Mitigation Strategy
Implement regular audits of documentation to ensure specificity.
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.
