Burns of 80-89% of body surfc w 0% to 9% third degree burns

This diagnosis code signifies extensive burn injuries affecting 80% to 89% of the patient's total body surface area (TBSA). Crucially, within this significant burn extent, the proportion of third-degree burns is minimal, ranging from 0% to 9%. This indicates a large area of superficial or partial-thickness burns with very limited full-thickness tissue destruction.

This code is appropriate for patients presenting with widespread burns covering nearly the entire body, where the majority of the injury involves first or second-degree burns. It would be used in cases where a comprehensive assessment confirms the TBSA burned falls within the 80-89% range, and the most severe (third-degree) burns constitute less than 10% of that total.

• Always confirm both the total body surface area burned and the percentage of third-degree burns from the physician's documentation.
• Do not use this code if the third-degree burn percentage is 10% or greater, even if the total burn extent is within the 80-89% range.
• Remember to code any associated external cause of the burn and the burn site(s) as additional diagnoses.
