What This Code Means

Chemical burn affecting 70-79% of the body surface with 10-19% deep tissue damage (third degree corrosion). This is a critical chemical injury with extensive body surface involvement and moderate full-thickness burns.

Coding Tips

•Document the source and type of chemical agent involved for complete clinical documentation
•Include the seventh character extension to properly classify the episode of care

Clinical Significance

This represents extensive chemical burns affecting 70-79% of the body with moderate full-thickness involvement (10-19% third-degree), indicating critical injury requiring immediate burn center management. These patients face significant mortality risk and require intensive medical care, surgical intervention, and prolonged rehabilitation with high potential for complications.

Documentation Requirements

✓Total body surface area (70-79%)
✓Third-degree burn extent (10-19%)
✓Chemical agent identification
✓Exposure circumstances and timeline
✓Current treatment phase
✓Anatomical areas involved
✓Associated complications or organ dysfunction
✓Surgical procedures and wound care
