HCC Category Mapping

What This Code Means

A rare heart defect where both the pulmonary artery and aorta originate from the left ventricle instead of their normal positions.

Coding Tips

• •Document the anatomical relationship of the great arteries
• •Note any associated ventricular septal defects or other cardiac anomalies

Clinical Significance

Double outlet left ventricle is an extremely rare congenital heart defect where both great arteries arise from the left ventricle, creating complex hemodynamic abnormalities. This condition requires specialized pediatric cardiac care and often multiple surgical procedures to establish adequate circulation.

Documentation Requirements

• ✓Echocardiographic confirmation of both great arteries from left ventricle
• ✓Associated ventricular septal defect location and size
• ✓Hemodynamic assessment and impact
• ✓Surgical planning and intervention history
• ✓Current cardiac function and output
• ✓Associated congenital anomalies
• ✓Growth and development monitoring
• ✓Specialized cardiac center follow-up
