What This Code Means

A severe chemical burn affecting 80-89% of the body surface, with the deepest burns (third degree) covering 30-39% of the affected area. This is an extremely critical injury with very high mortality and morbidity risk.

Coding Tips

•Verify burn center transfer documentation and ensure appropriate codes for transfer of care are applied
•Monitor for systemic complications including infection, organ failure, and metabolic derangements

Clinical Significance

This represents extremely critical chemical burns covering 80-89% of the body with extensive full-thickness destruction (30-39% third-degree), indicating potentially fatal injury with very high mortality risk. These patients require immediate burn center care with extensive surgical intervention and face grave prognosis with significant risk of death or severe permanent disability.

Documentation Requirements

✓Third-degree burn percentage (30-39%)
✓Chemical agent and exposure circumstances
✓Timeline of injury and care
✓Current treatment status
✓Anatomical involvement pattern
✓Associated organ dysfunction
✓Extensive surgical procedures
