Key Information: ICD-10 Coding for Heart Failure with Reduced Ejection Fraction

Essential facts and insights about ICD-10 Coding for Heart Failure with Reduced Ejection Fraction

Use ICD-10 code I50.20 for unspecified systolic (congestive) heart failure, ensuring proper documentation in clinical notes.

Primary ICD-10-CM Codes

Unspecified systolic (congestive) heart failure

Billable Code
I50.20
Billable

Diagnostic Criteria

  • • Lack of acuity specification in documentation.

Applicable To

  • • Systolic heart failure NOS

Important Notes

  • • Ensure documentation specifies acuity to avoid using unspecified codes.

Acute systolic (congestive) heart failure

Billable Code
I50.21
Billable

Diagnostic Criteria

  • • LVEF ≤40%
  • • Acute onset of symptoms such as dyspnea or orthopnea

Applicable To

  • • Acute heart failure with reduced ejection fraction

Important Notes

  • • Document acute symptoms and LVEF to support code use.

Chronic systolic (congestive) heart failure

Billable Code
I50.22
Billable

Diagnostic Criteria

  • • LVEF ≤40%
  • • Stable symptoms managed with medication

Applicable To

  • • Chronic heart failure with reduced ejection fraction

Important Notes

  • • Document chronic management and LVEF to support code use.

Acute on chronic systolic (congestive) heart failure

Billable Code
I50.23
Billable

Diagnostic Criteria

  • • LVEF ≤40%
  • • Documentation of both chronic baseline and acute exacerbation

Applicable To

  • • Acute exacerbation of chronic heart failure with reduced ejection fraction

Important Notes

  • • Document both chronic and acute components to support code use.
Ancillary Codes

Additional codes that may be used with this diagnosis

I11.0

Hypertensive heart disease with heart failure

Use when hypertension is documented as contributing to heart failure.

I25.10

Atherosclerotic heart disease of native coronary artery without angina pectoris

Use when coronary artery disease is documented.

Frequently Asked Questions

What is the ICD-10 code for HFrEF?

The ICD-10 code for Heart Failure with Reduced Ejection Fraction (HFrEF) is typically coded under the I50.2x series, which includes specific codes for acute, chronic, and acute on chronic systolic heart failure.

How do you document HFrEF?

Document HFrEF by specifying the acuity (acute, chronic, or acute on chronic) and including the left ventricular ejection fraction (LVEF) percentage.
