Corros unsp deg mult right fngr (nail), not inc thumb, init

This code describes chemical damage to multiple fingers on the right hand, excluding the thumb, where the specific depth or severity of the corrosion is not documented. It indicates the initial treatment or evaluation for this injury.

Apply this code when a patient presents with chemical burns to several right-hand fingers (not the thumb), and the medical record does not specify whether the corrosion is first, second, or third degree. This is appropriate for the first visit for this specific injury.

• Ensure documentation specifies "multiple" fingers and excludes the thumb.
• Only use the "A" seventh character for the initial encounter for this injury.
• Confirm the laterality is "right" and the etiology is "corrosion" (chemical burn).
