Corros 60-69% of body surface w 30-39% third degree corros

This code signifies a severe chemical burn, or corrosion, affecting a significant portion of the patient's body surface, specifically between 60% and 69%. Within this affected area, a substantial portion, 30% to 39%, has sustained full-thickness tissue damage, indicating third-degree corrosion. This level of injury involves destruction of the epidermis and dermis, often extending into subcutaneous tissue.

Apply this code when documentation clearly states a chemical burn covering 60-69% of the total body surface area (TBSA), with 30-39% of that TBSA being full-thickness (third-degree) corrosion. This is typically seen in cases of extensive industrial accidents or severe chemical exposures. Ensure the physician's documentation explicitly quantifies both the total body surface area affected and the percentage of third-degree involvement.

• Always verify the percentage of total body surface area (TBSA) affected by corrosion and the percentage of third-degree involvement from the physician's notes.
• Do not use this code for thermal burns; it is specific to corrosions (chemical burns).
• Remember to also code for the external cause of the corrosion (e.g., exposure to corrosive chemicals) and any associated complications.
