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

This code signifies a severe burn injury affecting a significant portion of the patient's total body surface area (TBSA), specifically between 70% and 79%. Within this extensive burn, a substantial proportion (also 70% to 79%) is classified as full-thickness (third-degree) burns, indicating damage to all layers of the skin and potentially underlying tissues.

Apply this code for patients presenting with extensive burns where the physician documentation clearly specifies that 70-79% of the body surface is involved, and within that burned area, 70-79% are identified as third-degree burns. This is typically used in acute care settings for initial burn assessment and subsequent treatment planning.

• Ensure physician documentation explicitly states both the total body surface area burned and the percentage of third-degree burns within that total.
• Do not use this code if the percentages for total burn or third-degree burn fall outside the 70-79% range.
• Always sequence this code first for the burn injury, followed by codes for specific burn sites and any associated complications.
