Burns of 90%/more of body surfc w 90%/more third deg burns

This code signifies an extremely severe burn injury affecting nearly the entire body surface, with the vast majority of the burned area being full-thickness (third-degree) burns. These extensive burns penetrate all layers of the skin, often damaging underlying tissues, and represent a life-threatening condition requiring intensive critical care.

Apply this code for patients presenting with burns covering 90% or more of their total body surface area (TBSA), where 90% or more of that burned area is classified as third-degree. This is typically seen in catastrophic burn events, often involving large-scale fires or explosions, leading to widespread tissue destruction.

• Always ensure documentation clearly specifies both the total body surface area (TBSA) affected and the percentage of third-degree burns within that TBSA.
• This code is for the extent and depth of the burn; additional codes for the specific burn site(s) and external cause are also required.
• Verify that the physician's assessment aligns with the "90% or more" threshold for both TBSA and third-degree involvement.
