Corros 3rd deg mu right fingers (nail), inc thumb, init

This code signifies a severe chemical burn affecting multiple fingers, including the thumb, on the patient's right hand. The corrosion has penetrated all layers of the skin, indicating full-thickness tissue destruction, specifically involving the nail beds.

This code is appropriate for the initial encounter of a patient presenting with third-degree chemical burns to several right-hand fingers and thumb, with documented involvement of the nail. It would be used when the patient is first seen for this specific injury, such as in an emergency department or initial clinic visit.

• Ensure documentation clearly specifies "corrosion" (chemical burn) rather than thermal burn.
• Verify that multiple fingers on the right hand, including the thumb, are affected, and the burn is explicitly third-degree.
• Confirm this is the initial encounter for this specific injury; subsequent encounters will require different seventh characters.
