I50.41

HCC Category Mapping

What This Code Means

A sudden onset of combined heart failure affecting both the heart's pumping function and its ability to relax, causing acute symptoms and fluid buildup.

Coding Tips

• •Verify documentation explicitly states 'acute' combined systolic and diastolic dysfunction
• •Confirm both systolic and diastolic components are documented before assigning this code

Clinical Significance

Acute combined systolic and diastolic congestive heart failure represents a sudden onset of dual ventricular dysfunction where both pumping ability and relaxation are impaired. This represents severe acute cardiac compromise requiring immediate intervention. The combination of both dysfunction types indicates more critical disease than isolated systolic or diastolic failure.

Documentation Requirements

• ✓Provider must document 'acute' combined systolic and diastolic heart failure
• ✓Clinical evidence of acute decompensation with both types of dysfunction
• ✓Echocardiographic evidence of reduced ejection fraction AND diastolic filling abnormalities
• ✓Precipitating factors for the acute event
• ✓Response to acute treatment
• ✓Distinction from acute on chronic — implies no pre-existing chronic combined heart failure
