HCC Category Mapping

What This Code Means

Heart failure that develops as a long-term consequence of rheumatic heart disease, where the damaged valves prevent the heart from pumping effectively.

Coding Tips

• •Ensure documentation establishes the causal relationship between rheumatic heart disease and the heart failure
• •Code the type of heart failure (systolic, diastolic, etc.) separately if documented

Clinical Significance

Rheumatic heart failure represents heart failure as a consequence of rheumatic heart disease, typically resulting from prior rheumatic fever causing permanent valvular damage. This condition reflects advanced cardiac disease with significant morbidity and mortality. Capturing both the rheumatic etiology and the heart failure is important for accurate risk adjustment and care planning.

Documentation Requirements

• ✓Documented history of rheumatic fever or rheumatic heart disease
• ✓Clinical evidence of heart failure (dyspnea, edema, reduced exercise tolerance)
• ✓Echocardiographic findings showing valvular disease consistent with rheumatic etiology
• ✓Heart failure classification (systolic, diastolic, or combined; NYHA class if documented)
• ✓Ejection fraction if available
• ✓Current treatment regimen including medications (diuretics, ACE inhibitors, etc.)
• ✓Documentation linking the heart failure causally to the rheumatic heart disease
