0.000What This Code Means
Severe chemical burn covering 80-89% of the body with the deepest burns affecting 60-69% of that area. This represents an extremely critical injury with high mortality risk.
Coding Tips
- •Verify documentation clearly distinguishes between corrosion (chemical) and thermal burns, as this affects code selection
- •Ensure the seventh character extension is included to indicate whether this is the initial encounter, subsequent visit, or sequela
Clinical Significance
This indicates extremely severe chemical burns affecting 80-89% of the body where the majority of affected area has full-thickness destruction (60-69% third-degree), representing near-fatal injury with exceptional mortality risk. These patients require immediate burn center intervention with aggressive surgical management and face critical prognosis with extensive tissue loss.
Documentation Requirements
- ✓Body surface area involvement (80-89%)
- ✓Third-degree burn extent (60-69%)
- ✓Specific chemical agent and exposure details
- ✓Timeline of injury and emergency care
- ✓Current treatment status and response
- ✓Anatomical distribution of burns
- ✓Associated complications and organ dysfunction
- ✓Extensive surgical interventions required
