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

This code signifies a severe burn injury affecting a significant portion of the body. Specifically, it indicates that 20-29% of the patient's total body surface area (TBSA) has sustained burns, and within that affected area, 20-29% of the burns are full-thickness (third-degree). This combination points to a critical burn requiring extensive medical intervention.

This code is appropriate for patients presenting with extensive burns where a precise assessment confirms that between one-fifth and just under one-third of their body has been burned, and a substantial portion of those burns are full-thickness. It would be used after a thorough evaluation, often involving a burn unit or specialized burn care. This code is typically assigned for initial encounters for such injuries.

• Ensure accurate documentation of both total body surface area (TBSA) burned and the percentage of third-degree burns within that TBSA.
• This code is for initial encounters; subsequent encounters for healing or complications will require different codes.
• Always review the "Rule of Nines" or Lund-Browder chart documentation to verify the percentages before assigning this code.
