Burns of 30-39% of body surface w 30-39% 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 30% and 39%. Crucially, within this affected area, 30% to 39% of the burns are classified as full-thickness (third-degree), indicating extensive tissue damage.

This code is appropriate for patients presenting with extensive burn injuries where a precise calculation of TBSA burned falls within the 30-39% range, and a substantial portion (also 30-39%) of those burns are documented as third-degree. This typically applies to major burn trauma requiring specialized medical intervention.

• Ensure documentation clearly specifies both the total body surface area burned and the percentage of third-degree burns.
• Do not use this code if the percentages for total burn or third-degree burn fall outside the 30-39% range.
• Always sequence this code first when it represents the primary reason for the encounter, followed by codes for specific burn sites.
