Corros 70-79% of body surface w 10-19% third degree corros

This code signifies a severe chemical or thermal burn (corrosion) affecting a substantial portion of the patient's total body surface area (TBSA), specifically between 70% and 79%. Within this extensive burn, a significant portion, 10% to 19%, is classified as third-degree, indicating full-thickness tissue destruction.

This code is appropriate for patients presenting with extensive corrosive injuries where the total body surface area involved is precisely documented as 70-79%, and the third-degree component is specifically identified as 10-19% of the TBSA. This often occurs in industrial accidents, chemical exposures, or severe thermal incidents.

• Ensure precise documentation of both total body surface area (TBSA) and the percentage of third-degree corrosion.
• Do not use this code if the TBSA or third-degree percentage falls outside the specified ranges (e.g., 69% TBSA or 20% third-degree).
• Always sequence this code after any external cause codes (e.g., X-codes) that describe the mechanism of injury.
