Corrosion of third degree of right wrist, initial encounter

This code signifies a severe chemical burn affecting the entire thickness of the skin and underlying tissues of the patient's right wrist. The injury results in full destruction of the skin layers, often appearing charred, waxy, or leathery, and typically involves nerve damage leading to a lack of sensation.

Apply this code for initial treatment of a patient presenting with a third-degree chemical burn to the right wrist. This includes the initial assessment, debridement, and any immediate surgical interventions or wound care performed during the first encounter for this specific injury.

• Ensure documentation clearly specifies the cause as "corrosion" (chemical burn) and not a thermal burn.
• Verify the laterality (right wrist) and the depth of the burn (third degree) are explicitly stated in the medical record.
• The "A" suffix indicates an initial encounter, meaning the patient is receiving active treatment for the injury.
