What This Code Means

Catastrophic chemical burn covering 90% or more of the body with 20-29% showing the deepest, most severe burns. This represents massive injury with significant deep tissue destruction.

Coding Tips

•Verify documentation clearly specifies chemical corrosion rather than thermal burn to ensure correct code selection
•Include seventh character extension and coordinate with burn center protocols for documentation of fluid resuscitation and treatment

Clinical Significance

This indicates catastrophic chemical burns affecting 90% or more of the body with significant full-thickness destruction (20-29% third-degree), representing near-fatal injury with exceptional mortality risk. These patients require immediate specialized burn center care with aggressive surgical intervention and represent the most severe chemical burn injuries with massive tissue destruction.

Documentation Requirements

✓Body surface area involvement (90% or greater)
✓Third-degree burn extent (20-29%)
✓Chemical agent causing massive injury
✓Exposure details and duration
✓Current care phase and viability
✓Specific anatomical areas affected
✓Multiple organ complications
✓Extensive surgical interventions
