Key Information: ICD-10 code for acute HFpEF

Essential facts and insights about Acute HFpEF

The ICD-10 code for acute HFpEF is I50.31, indicating acute diastolic heart failure.

Primary ICD-10-CM Code for acute hfpef

Acute diastolic heart failure
Billable Code

Decision Criteria

clinical Criteria

  • Ejection fraction ≥50% with acute symptoms

documentation Criteria

  • Explicit mention of 'acute diastolic heart failure' or 'acute HFpEF'

Applicable To

  • Acute heart failure with preserved ejection fraction

Excludes

  • Chronic diastolic heart failure (I50.32)
  • Unspecified heart failure (I50.9)

Clinical Validation Requirements

  • Ejection fraction ≥50%
  • Acute decompensation symptoms such as pulmonary edema
  • Elevated BNP or NT-proBNP levels

Code-Specific Risks

  • Misclassification as chronic diastolic heart failure
  • Use of unspecified heart failure codes

Coding Notes

  • Ensure documentation explicitly states 'acute diastolic heart failure' or 'acute HFpEF'.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Fluid overload

E87.70
Use if hypervolemia is present alongside acute HFpEF.

Hypertensive heart disease with heart failure

I11.0
Use if hypertensive heart disease is a contributing factor.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Chronic diastolic heart failure

I50.32
Use for stable, non-acute cases with preserved ejection fraction.

Heart failure, unspecified

I50.9
Avoid when EF and type are documented.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Acute HFpEF to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.31.

Impact

Clinical: Leads to inappropriate treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential loss of reimbursement.

Mitigation Strategy

Always document the acuity (acute, chronic, acute on chronic).

Impact

Reimbursement: May lead to incorrect DRG assignment and reimbursement., Compliance: Triggers audits due to lack of specificity., Data Quality: Reduces accuracy of clinical data.

Mitigation Strategy

Ensure EF and type are documented to use specific codes like I50.31.

Impact

High audit risk when EF and type are documented but unspecified codes are used.

Mitigation Strategy

Ensure documentation includes EF and specifies diastolic or HFpEF.

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.

Frequently Asked Questions

Common questions about ICD-10 coding for Acute HFpEF, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Acute HFpEF

Use these documentation templates to ensure complete and accurate documentation for Acute HFpEF. These templates include all required elements for proper coding and billing.

Acute decompensated HFpEF admission

Specialty: Cardiology

Required Elements

  • Ejection fraction percentage
  • BNP or NT-proBNP levels
  • Symptoms of acute decompensation

Example Documentation

Admitted for acute decompensated HFpEF with EF 55%, pulmonary edema, and BNP 800 pg/mL.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient admitted with heart failure.
Good Documentation Example
Patient admitted with acute decompensated HFpEF, EF 55%, BNP 800 pg/mL.
Explanation
The good example specifies the type of heart failure and provides clinical validation.
