Corros 80-89% of body surface w 60-69% third degree corros

This code signifies a severe chemical or electrical burn (corrosion) affecting a very large portion of the patient's body, specifically between 80% and 89% of the total body surface area. A significant portion of this extensive injury, between 60% and 69%, is classified as third-degree, indicating full-thickness tissue destruction.

This code is appropriate for patients presenting with life-threatening chemical or electrical burns that cover nearly the entire body. It should be assigned when documentation clearly specifies the total body surface area (TBSA) affected by corrosion is within the 80-89% range, and the third-degree component is between 60-69% of that TBSA. This often applies to industrial accidents or severe electrical injuries.

• Ensure the documentation explicitly states both the total body surface area affected by corrosion and the percentage of third-degree involvement.
• Do not use this code if the injury is thermal (fire, heat); use the appropriate burn codes instead.
• Always sequence this code first if it represents the primary reason for the encounter.
