Burns of 90%/more of body surfc w 30-39% third degree burns

This code signifies a critical burn injury affecting at least 90% of the patient's total body surface area (TBSA), with a significant portion (30-39%) of these burns being full-thickness (third-degree). Such extensive and deep burns indicate severe tissue damage, often involving muscle, bone, and nerve endings, leading to profound systemic effects.

Apply this code for patients presenting with massive burn injuries where the total body surface area involved is 90% or greater, and a detailed assessment confirms that 30% to 39% of that extensive burn area is classified as third-degree. This is typically seen in catastrophic burn events requiring immediate and intensive critical care.

• Ensure accurate documentation of both total burn surface area (TBSA) and the percentage of third-degree burns.
• This code is highly specific; verify that both the overall TBSA (90%+) and the third-degree percentage (30-39%) are met.
• Do not use this code if the percentage of third-degree burns falls outside the 30-39% range, even if the total body surface area is 90% or more.
