What is the ICD-10 code for CHFpEF?

The ICD-10 code for Congestive Heart Failure with Preserved Ejection Fraction (CHFpEF) is I50.3-, which includes acute, chronic, and acute on chronic diastolic heart failure.

How do you document HFpEF?

Document HFpEF by specifying the ejection fraction (EF ≥50%), acuity (acute, chronic, acute on chronic), and any underlying causes such as hypertension.

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
I50.31	Acute diastolic (congestive) heart failure	Use when acute symptoms of diastolic heart failure are present with EF >50%.	Ejection fraction >50% Symptoms of acute heart failure such as pulmonary edema
I50.32	Chronic diastolic heart failure	Use for chronic diastolic heart failure with EF >50%.	Ejection fraction >50% Chronic symptoms of heart failure such as fatigue dyspnea
I50.33	Acute on chronic diastolic heart failure	Use for acute exacerbations on a background of chronic diastolic heart failure.	Ejection fraction >50% Combination of acute and chronic heart failure symptoms

Use when EF <40% indicating systolic dysfunction.

Documentation & Coding Risks

Avoid these common issues when documenting Congestive Heart Failure with Preserved Ejection Fraction.

Documenting 'diastolic dysfunction' without linking to heart failure

Impact

Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with coding standards requiring specificity., Financial: Potential for denied claims due to lack of specificity.

Mitigation

Always link diastolic dysfunction to heart failure in documentation.

Using 'CHF' without specifying type

Impact

Reimbursement: May lead to lower reimbursement due to unspecified code I50.9., Compliance: Non-compliance with coding guidelines for specificity., Data Quality: Reduces accuracy of clinical data and outcomes tracking.

Mitigation

Specify 'diastolic' or 'HFpEF' to avoid unspecified coding.

Unspecified Heart Failure Coding

Impact

Risk of audits due to high use of unspecified codes like I50.9.

Mitigation

Ensure documentation specifies type and acuity of heart failure.
