Corrosion of third degree of unsp hand, unsp site, init

This code signifies a severe chemical burn affecting the full thickness of the skin and underlying tissues of an unspecified hand. The injury involves destruction of all skin layers, often presenting with a leathery appearance, numbness, and potential damage to nerves, blood vessels, and muscle.

Apply this code when documentation confirms a third-degree corrosion to any part of the hand, and the specific location on the hand (e.g., palm, dorsum, finger) is not specified. This code is appropriate for the initial treatment of such an injury, prior to any subsequent care or healing phases.

• Ensure the documentation clearly states "corrosion" (chemical burn) and not a thermal burn.
• Only use this code when the specific site on the hand is truly unknown or not documented.
• Verify this is the patient's first encounter for this specific injury.
