Burns of 70-79% of body surface w 50-59% third degree burns

This code signifies a severe burn injury affecting a large portion of the patient's total body surface area (TBSA), specifically between 70% and 79%. Within this extensive burn, a significant proportion, 50% to 59%, is classified as full-thickness (third-degree) burns, indicating deep tissue destruction.

Apply this code for patients presenting with extensive burns where the total body surface area involved is precisely documented as 70-79%, and the third-degree component is specifically identified as 50-59% of the total burn. This is typically used in acute care settings for initial burn assessment and subsequent treatment planning.

• Ensure documentation clearly specifies both the total burn percentage and the percentage of third-degree burns within that total.
• Do not use this code if the percentages fall outside the 70-79% total or 50-59% third-degree ranges.
• Always sequence this code first for burn encounters, followed by codes for specific burn sites and external cause codes.
