Burn of third degree of unspecified lower leg, init encntr

This code signifies a full-thickness burn affecting an unspecified area of the lower leg, indicating destruction of the epidermis, dermis, and often underlying subcutaneous tissue. The burn wound will appear leathery, charred, or waxy white, with absent sensation due to nerve damage. This specific code is for the initial treatment phase of the injury.

Apply this code when documenting a patient's first encounter for a third-degree burn to an unspecified lower leg, such as when the specific location (e.g., ankle, calf) is not documented or is unknown. This is appropriate for initial evaluations, emergency department visits, or the first inpatient admission for the burn.

• Ensure the documentation clearly specifies "third degree" and "lower leg."
• Only use the "A" (initial encounter) seventh character for the period of active treatment for the burn.
• If the specific lower leg (right or left) is known, a more specific code should be selected.
