Corros 60-69% of body surface w 40-49% third degree corros

This code signifies a severe chemical burn or corrosion affecting a significant portion of the body, specifically 60% to 69% of the total body surface area. Within this extensive damage, a substantial portion, 40% to 49%, is classified as third-degree, indicating full-thickness tissue destruction. This level of injury involves damage to all layers of the skin and potentially underlying tissues.

This code is appropriate for patients presenting with extensive chemical burns where the total body surface area (TBSA) involved is precisely documented as 60-69%. Furthermore, the medical record must clearly indicate that 40-49% of this affected area exhibits third-degree damage. This is typically seen in industrial accidents or other severe exposures to corrosive substances.

• Ensure the medical record 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 percentages for total body surface area or third-degree corrosion fall outside the specified ranges.
• Remember to also code for any associated complications, such as infection or respiratory involvement, if present.
