Burn of third degree of unspecified ankle, initial encounter

This code signifies a severe burn affecting all layers of skin and potentially underlying tissue on an unspecified ankle. It indicates a full-thickness injury that results in tissue destruction and often requires surgical intervention. The "initial encounter" aspect specifies that this code is used for the first time a patient is seen for this particular burn injury.

Apply this code when documenting a patient presenting with a third-degree burn to their ankle, where the specific ankle (left or right) is not documented or known. This is appropriate for the initial assessment and treatment of the burn, such as in an emergency department or during the first inpatient admission for the injury.

• Ensure documentation clearly specifies "third degree" and "ankle" as the burn site.
• Only use the "A" (initial encounter) seventh character for the active treatment phase of the burn.
• If the specific ankle (left or right) is documented, use the more specific code (T25.311A or T25.312A).
