Heart failure codes including systolic, diastolic, and unspecified types
This range includes all relevant codes for congestive heart failure exacerbation, covering different types and acuity levels.
Hypertensive heart disease with heart failure
These codes are used when heart failure is due to hypertension, often requiring sequencing before heart failure codes.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I50.23 | Acute on chronic systolic heart failure | Use when acute decompensation occurs in a patient with chronic systolic heart failure. |
|
| I50.33 | Acute on chronic diastolic heart failure | Use when acute decompensation occurs in a patient with chronic diastolic 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 congestive heart failure exacerbation
Decision Criteria
clinical Criteria
- EF ≤40% and acute symptoms
documentation Criteria
- Documented acute decompensation
Applicable To
- Acute decompensation of chronic systolic heart failure
Excludes
- Diastolic heart failure
- Unspecified heart failure
Clinical Validation Requirements
- Ejection fraction ≤40%
- Prior CHF history
- Response to diuretics
Code-Specific Risks
- Coding without EF or BNP documentation
Coding Notes
- Ensure documentation specifies systolic dysfunction with acute exacerbation.
I50.33 - Acute on chronic diastolic heart failure
Use when acute decompensation occurs in a patient with chronic diastolic heart failure.
Applicable To
- Acute diastolic failure with pulmonary edema
Excludes
- Systolic heart failure
- Unspecified heart failure
Clinical Validation Requirements
- Ejection fraction ≥50%
- BNP >900 pg/mL for age >75
Coding Notes
Ensure documentation specifies diastolic dysfunction with acute exacerbation.
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 Congestive 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 decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Ensure echocardiogram results are included in the documentation., Train staff on the importance of EF documentation.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Query for systolic/diastolic specificity if not documented.
Impact
Using unspecified codes when specific documentation is available.
Mitigation Strategy
Implement regular audits and training to ensure specificity in documentation.
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.
