Corros unsp degree of unsp mult fngr (nail), inc thumb, init

This code signifies damage to the skin and/or underlying tissue of multiple fingers, including the thumb, due to a chemical burn or corrosive substance. The specific depth of the burn (e.g., first, second, or third degree) is not documented or is unknown. This code is used for the initial treatment of such an injury.

Apply this code when a patient presents with a chemical burn affecting more than one finger, including the thumb, and the degree of the burn is not specified in the medical record. This is appropriate for the first encounter for this specific injury.

• Ensure documentation explicitly states "multiple fingers" and includes the thumb, and that the burn is due to corrosion.
• Only use this code for the initial treatment of the injury; subsequent encounters will require a different seventh character.
• If the degree of corrosion is known and documented, a more specific code should be selected.
