What This Code Means

Catastrophic chemical burn covering 90% or more of the body with 30-39% showing the deepest, most severe burns. This indicates extensive full-thickness injury with critical prognosis.

Coding Tips

•Ensure all documentation specifies the extent of third-degree corrosion separately from the total body surface area percentage
•Include seventh character and coordinate with codes for specific body regions affected and any associated complications

Clinical Significance

This represents catastrophic chemical burns covering 90% or more of the body with extensive full-thickness destruction (30-39% third-degree), indicating potentially fatal injury with extremely high mortality risk. These patients require immediate intensive burn care with extensive surgical reconstruction and represent among the most severe chemical injuries possible with critical prognosis.

Documentation Requirements

✓Total body surface area (90% or greater)
✓Third-degree burn percentage (30-39%)
✓Chemical agent and exposure circumstances
✓Timeline of injury and emergency care
✓Current treatment status
✓Anatomical involvement pattern
✓Associated organ dysfunction
✓Extensive surgical procedures
