Corros 3rd deg mu right fingers (nail), not inc thumb, init

This code signifies a severe, full-thickness chemical burn affecting multiple fingers on the right hand, excluding the thumb. The corrosion has damaged all layers of skin and potentially underlying tissue, specifically involving the nail area.

Apply this code when documentation confirms a third-degree chemical burn to several right-hand fingers (excluding the thumb), with specific mention of the nail or nail bed involvement. This is appropriate for the initial treatment of such an injury.

• Ensure the documentation specifies "corrosion" or "chemical burn" and not a thermal burn.
• Verify the degree of the burn is explicitly stated as "third degree" and involves multiple right fingers, excluding the thumb.
• Confirm this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
