What This Code Means

Catastrophic chemical burn covering 90% or more of the body with 40-49% showing the deepest, most severe burns. This represents severe full-thickness injury affecting nearly half of the burned area.

Coding Tips

•Document the causative chemical agent and concentration if known, as this impacts treatment and prognosis
•Seventh character extension is required; ensure coordination with documentation of burn center admission and specialized burn care protocols

Clinical Significance

This indicates catastrophic chemical burns affecting 90% or more of the body with massive full-thickness destruction (40-49% third-degree), representing near-fatal injury with exceptional mortality risk. These patients require immediate specialized burn center intervention with extensive surgical reconstruction and face grave prognosis with high likelihood of death or profound disability.

Documentation Requirements

✓Body surface area documentation (90% or greater)
✓Third-degree burn extent (40-49%)
✓Chemical agent identification and concentration
✓Exposure timeline and circumstances
✓Current care phase and viability assessment
✓Detailed anatomical distribution
✓Multiple organ complications
✓Extensive surgical interventions and grafting
