Burns of 40-49% of body surface w 20-29% third degree burns

This code signifies a severe burn injury affecting nearly half of the patient's total body surface area (TBSA). Specifically, 40-49% of the body has sustained burns, with a significant portion (20-29%) of these burns being full-thickness (third-degree). This indicates extensive tissue damage requiring intensive medical intervention.

This code is appropriate for patients presenting with extensive burn injuries where the physician documentation clearly specifies the TBSA involved and the percentage of third-degree burns falls within the specified ranges. It is typically used in acute care settings, such as emergency departments or burn units, following initial assessment and documentation of burn extent and depth.

• Ensure physician documentation explicitly states both the total body surface area burned and the percentage of third-degree burns.
• Do not assign this code if the percentages for total burn or third-degree burn fall outside the specified ranges.
• Remember to also code for any associated complications, such as smoke inhalation or infection, as well as the external cause of the burn.
