Burns of 90%/more of body surfc w 70-79% third degree burns

This diagnosis code signifies a critical burn injury affecting at least 90% of the patient's total body surface area. Within this extensive burn, a significant portion, specifically 70% to 79%, is classified as full-thickness (third-degree) burns. This indicates severe damage to the skin and underlying tissues across a vast area of the body.

Use this code for patients presenting with life-threatening burns where the total body surface area involved is 90% or greater, and the extent of third-degree burns within that total is precisely documented as 70% to 79%. This typically applies to severe trauma cases requiring intensive care and specialized burn unit management.

• Ensure documentation clearly specifies both the total body surface area burned (90% or more) and the percentage of third-degree burns (70-79%).
• Do not use if the percentage of third-degree burns falls outside the 70-79% range, even if the total body surface area is 90% or more.
• Always sequence this code as the primary diagnosis when it represents the reason for the encounter.
