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

This code signifies a chemical burn affecting multiple fingers on the right hand, excluding the thumb, where the specific depth of the burn is not documented. The injury involves the nail and is being treated in a follow-up encounter after initial care.

Apply this code when a patient presents for subsequent treatment of a chemical burn to multiple right fingers (excluding the thumb), impacting the nail, and the degree of corrosion is unspecified. This is appropriate for office visits, wound care, or other follow-up appointments related to the initial injury.

• Ensure the documentation specifies "multiple" right fingers, not including the thumb, and involves the nail.
• Confirm the encounter is for subsequent care, not the initial treatment of the injury.
• If the degree of corrosion is documented (e.g., first, second, or third degree), a more specific code should be used.
