Burns of 70-79% of body surface w 30-39% third degree burns

This code signifies a severe burn injury affecting a significant portion of the body, specifically 70% to 79% of the total body surface area. Within this extensive burn, a substantial component, 30% to 39%, is classified as full-thickness (third-degree) burns, indicating damage through all layers of the skin.

Apply this code for patients presenting with extensive burn injuries where the total body surface area (TBSA) burned falls within the 70-79% range, and the third-degree component constitutes 30-39% of that total. This is typically seen in critical burn cases requiring intensive care and specialized burn unit management.

• Ensure accurate documentation of both total body surface area burned and the percentage of third-degree burns.
• Do not use this code if the percentages for total or third-degree burns fall outside the specified ranges.
• Always sequence this code as the principal diagnosis when it is the primary reason for admission.
