What This Code Means

Chemical burn affecting 10-19% of the body surface with moderate deep tissue damage (10-19% third degree burns).

Coding Tips

•Ensure documentation clearly specifies both the total body surface percentage and the third degree burn percentage
•Consider burn center referral criteria and document severity for appropriate level of care

Clinical Significance

Corrosions involving 10-19% of body surface area with equivalent third-degree involvement represent significant chemical burn injury requiring specialized treatment protocols. Chemical burns often continue to cause tissue damage until the causative agent is neutralized, making early recognition and appropriate decontamination critical for preventing progression to deeper injury and systemic toxicity.

Documentation Requirements

✓Documentation of 10-19% total body surface area involvement from chemical exposure
✓Clear documentation that 10-19% of affected area has third-degree corrosion
✓Identification of the specific chemical agent involved if known
✓Documentation of decontamination procedures performed
✓Assessment of ongoing chemical activity and tissue damage progression
✓Evidence of specialized chemical burn treatment protocols
✓Documentation of systemic toxicity assessment and monitoring
✓Treatment plan addressing both local and systemic chemical effects
