I50.22

HCC Category Mapping

What This Code Means

A long-term condition where the heart's left chamber gradually loses its ability to pump blood effectively, leading to persistent fluid accumulation and fatigue.

Coding Tips

• •Confirm documentation indicates 'chronic' or 'long-standing' systolic dysfunction
• •Verify this is not an acute exacerbation; if acute worsening occurs, use I50.23 instead

Clinical Significance

Chronic systolic congestive heart failure (chronic heart failure with reduced ejection fraction) reflects an ongoing condition requiring lifelong management with guideline-directed medical therapy. These patients have persistently reduced left ventricular function and are at continued risk for decompensation, arrhythmia, and death. Accurate annual recapture is essential for risk adjustment.

Documentation Requirements

• ✓Provider must document 'chronic' systolic heart failure or chronic heart failure with reduced ejection fraction
• ✓Ejection fraction value, typically less than 40%
• ✓Current guideline-directed medical therapy and compliance status
• ✓New York Heart Association functional class
• ✓Monitoring plan including follow-up schedule and lab monitoring
• ✓Absence of current acute exacerbation — if worsening, code I50.23 instead
