RxHCCHCC 191 — Congenital Heart/Circulatory Disorders and Fontan Circulation
0.000What This Code Means
A rare heart defect where the main blood vessels leaving the heart are connected to the wrong chambers, causing improper blood circulation.
Coding Tips
- •This is a complex congenital heart defect often requiring surgical intervention; ensure documentation specifies the exact vessel-chamber connections
- •Commonly associated with other cardiac anomalies; review records for additional defects that may require separate coding
Clinical Significance
Discordant ventriculoarterial connection involves the great arteries being connected to the wrong ventricles, creating life-threatening circulatory abnormalities. This complex condition requires immediate recognition and sophisticated surgical intervention to establish compatible circulation patterns.
Documentation Requirements
- ✓Detailed cardiac imaging showing discordant connections
- ✓Hemodynamic assessment and impact on circulation
- ✓Associated cardiac anomalies and complications
- ✓Surgical intervention planning and history
- ✓Current cardiac function and exercise capacity
- ✓Arrhythmia monitoring and management
- ✓Growth and development assessment
- ✓Long-term cardiac follow-up requirements
