What is the ICD-10 code for diastolic heart failure?

The ICD-10 code for diastolic heart failure is I50.3-, which includes acute, chronic, and acute on chronic conditions.

How do you code heart failure with preserved ejection fraction?

Heart failure with preserved ejection fraction (EF ≥50%) is coded as diastolic heart failure under ICD-10 code I50.3-.

Code Comparison: When to Use Each Code

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
I50.30	Unspecified diastolic heart failure	Use when diastolic heart failure is documented without specification of acuity.	Documentation of heart failure with preserved ejection fraction (EF ≥50%)
I50.31	Acute diastolic heart failure	Use when acute exacerbation of diastolic heart failure is documented.	Acute symptoms with EF ≥50% requiring immediate treatment.
I50.32	Chronic diastolic heart failure	Use for chronic diastolic heart failure without acute exacerbation.	Chronic symptoms with EF ≥50%.
I50.33	Acute on chronic diastolic heart failure	Use when acute exacerbation occurs on a chronic diastolic heart failure background.	Acute exacerbation on a background of chronic symptoms with EF ≥50%.

Differential Codes

Alternative codes to consider when ruling out similar conditions

Unspecified systolic heart failureI50.20

Use when EF is less than 50% or 'reduced EF' is documented.

Chronic diastolic heart failureI50.32

Use for chronic conditions without acute exacerbation.

Acute diastolic heart failureI50.31

Use for acute exacerbations.

Documentation & Coding Risks

Avoid these common issues when documenting Diastolic Heart Failure.

Omitting EF documentation in heart failure cases.

Impact

Clinical: Leads to misclassification of heart failure type., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.

Mitigation

Ensure EF is recorded in all heart failure diagnoses.

Coding diastolic heart failure without EF documentation.

Impact

Reimbursement: Potential for reduced reimbursement if coded as unspecified., Compliance: Risk of non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.

Mitigation

Ensure EF is documented as ≥50% to support diastolic heart failure coding.

Incorrectly coding chronic diastolic heart failure as acute.

Impact

Reimbursement: Incorrect DRG assignment may affect payment., Compliance: Non-compliance with coding standards., Data Quality: Misrepresents patient condition severity.

Mitigation

Verify documentation for acute symptoms and treatment before coding as acute.

Unspecified Heart Failure Coding

Impact

Using unspecified codes without supporting documentation.

Mitigation

Ensure EF and causal factors are documented to support specific coding.
