Burns of 70-79% of body surface w 40-49% third degree burns

This code signifies extensive burn injuries affecting 70% to 79% of the patient's total body surface area (TBSA). Within this significant burn area, a substantial portion, specifically 40% to 49%, consists of full-thickness (third-degree) burns. These are severe injuries requiring intensive medical intervention.

This code is appropriate for patients presenting with widespread burns where a precise assessment confirms the specified TBSA involvement and the percentage of third-degree burns. It is typically used in acute care settings, such as emergency departments or burn units, following initial stabilization and detailed burn assessment.

• Ensure documentation clearly specifies both the total burn surface area and the percentage of third-degree burns.
• Do not use this code if the percentages for TBSA or third-degree burns fall outside the 70-79% and 40-49% ranges, respectively.
• Always sequence this code after any codes for specific burn sites, if applicable, and before external cause codes.
