Unspecified systolic (congestive) heart failure

This code signifies heart failure primarily characterized by impaired ventricular contraction, leading to reduced ejection fraction, without further specification of acuity or severity. It indicates the heart's inability to pump sufficient blood to meet the body's metabolic demands due to a systolic dysfunction.

Use this code when the medical record clearly documents systolic heart failure but lacks specific details regarding its chronicity (acute, chronic, acute on chronic) or severity (e.g., compensated, decompensated). It is appropriate when the physician's diagnosis is simply "systolic heart failure" without further elaboration.

• Avoid using this code if more specific documentation of systolic heart failure (e.g., acute, chronic, acute on chronic) is available.
• Always query the provider for clarification if the documentation is vague regarding the type or acuity of heart failure.
• Do not confuse this with diastolic heart failure (I50.3x) or combined systolic and diastolic heart failure (I50.4x).
