Burns of 80-89% of body surface w 80-89% third degree burns

This code signifies a severe burn injury affecting a substantial portion of the patient's total body surface area (TBSA), specifically between 80% and 89%. Within this extensive burn, a high percentage, also 80% to 89%, is classified as full-thickness (third-degree) burns, indicating damage through all layers of the skin. Such injuries are life-threatening and require intensive medical intervention.

Apply this code for patients presenting with extensive burn injuries where clinical assessment confirms 80-89% TBSA involvement. This code is appropriate when the majority of these burns, specifically 80-89%, are documented as third-degree. This typically occurs in catastrophic burn events, often involving fire, chemicals, or electricity.

• Ensure physician documentation clearly specifies both the total body surface area burned and the percentage of third-degree burns.
• Do not use this code if the percentages for total burn or third-degree burn fall outside the 80-89% range.
• Always sequence this code as the principal diagnosis when it is the reason for the admission.
