What This Code Means

Chemical burn affecting 60-69% of the body surface with 50-59% deep tissue damage (third degree corrosion). This is a severe, potentially life-threatening chemical injury with majority deep tissue involvement.

Coding Tips

•Ensure coordination with trauma and burn specialists for appropriate management coding
•Include seventh character to denote initial encounter, subsequent visit, or sequela

Clinical Significance

This represents severe chemical burns affecting 60-69% of the body with majority deep tissue involvement (50-59% third-degree), indicating potentially fatal injury requiring immediate specialized burn care. These cases require extensive surgical intervention, prolonged hospitalization, and comprehensive rehabilitation with significant risk of permanent disability or death.
