What This Code Means

Severe chemical burn covering 80-89% of the body with the deepest, most severe burns affecting 50-59% of that area. This is a life-threatening injury requiring immediate intensive care.

Coding Tips

•This code requires documentation of both the total body surface area percentage (80-89%) and the extent of third-degree corrosion (50-59%)
•Always code with a seventh character for episode of care (A=initial, D=subsequent, S=sequela) and ensure documentation specifies chemical corrosion, not thermal burns

Clinical Significance

This represents severe chemical burns covering 80-89% of the body with majority deep tissue destruction (50-59% third-degree), indicating life-threatening injury requiring immediate intensive care. These patients face extremely high mortality risk and require extensive surgical intervention with prolonged specialized burn care and significant potential for death or severe disability.

Documentation Requirements

✓Total body surface area (80-89%)
✓Third-degree burn percentage (50-59%)
✓Chemical agent causing massive injury
✓Exposure details and contact duration
✓Current treatment phase and prognosis
✓Anatomical areas involved
✓Systemic complications and organ failure
✓Multiple surgical procedures and outcomes
