Corrosion of third degree of back of right hand, init encntr

This code signifies a full-thickness chemical burn affecting the back of the right hand, characterized by destruction of all skin layers, including subcutaneous tissue. The injury typically presents with a leathery appearance, insensitivity to touch, and may involve underlying structures.

Apply this code when documenting the initial treatment for a third-degree chemical burn to the dorsal aspect of the right hand. This includes scenarios such as chemical exposure in industrial settings, laboratory accidents, or household incidents resulting in severe tissue damage.

• Ensure documentation specifies "corrosion" or "chemical burn" and the "back of the right hand."
• The "A" suffix indicates an initial encounter for active treatment of the injury.
• Confirm the burn depth is explicitly stated as third-degree or full-thickness.
