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

This code signifies a severe burn injury affecting nearly half of the patient's total body surface area (TBSA). A substantial portion of these burns, also approaching half of the TBSA, are classified as third-degree, indicating full-thickness skin destruction. This level of injury often involves significant systemic effects and requires intensive medical management.

Use this code for patients presenting with extensive burns where approximately 40-49% of their body surface is affected, and within that affected area, 40-49% are full-thickness (third-degree) burns. This typically applies to cases documented by burn specialists following initial assessment and TBSA estimation.

• Ensure documentation clearly specifies both the total burn percentage and the percentage of third-degree burns.
• Verify that the percentages fall within the 40-49% range for both total body surface and third-degree involvement.
• Remember to also code for the specific burn sites and any associated complications.
