Burns of 70-79% of body surface w 20-29% 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 portion, 20% to 29%, is classified as full-thickness (third-degree) burns, indicating damage through all layers of the skin. Such injuries are life-threatening and require intensive medical intervention.

Use this code for patients presenting with extensive burns where the total body surface area involved is between 70% and 79%, and a detailed assessment confirms that 20% to 29% of these burns are third-degree. This code is appropriate for initial encounters and subsequent care during the acute phase of such severe burn injuries.

• Ensure accurate documentation of both total burn surface area (TBSA) and the percentage of third-degree burns.
• This code requires an additional code to identify the specific burn sites (e.g., T20-T25 series).
• Do not use this code for burns classified as first- or second-degree only, regardless of TBSA.
