What This Code Means

Severe chemical burns affecting 90% or more of the body with 70-79% of the burns being the most severe third-degree type that destroys all skin layers.

Coding Tips

•Document the extent of third-degree involvement (70-79%) separately from total body surface area involvement
•Requires seventh character extension for episode of care classification

Clinical Significance

This represents severe chemical burns affecting 90% or more of the body with the deepest burns covering 70-79% of that area. This indicates one of the most catastrophic chemical injuries possible, with near-total full-thickness destruction requiring immediate intensive care and extensive surgical reconstruction with grave prognosis.

Documentation Requirements

✓Total body surface area (90% or greater)
✓Third-degree burn percentage (70-79%)
✓Chemical agent causing catastrophic injury
✓Exposure circumstances and duration
✓Current care phase and survival assessment
✓Detailed anatomical involvement
✓Multiple organ complications
✓Extensive surgical procedures and grafting
