Corrosion of unspecified degree of chin, initial encounter

This code signifies a chemical burn of the chin, where the specific depth of the burn (e.g., first, second, or third degree) is not documented. It indicates damage to the chin tissue caused by corrosive substances, such as strong acids or alkalis.

Apply this code when a patient presents with a chemical burn to the chin, and the medical record does not specify the degree of the burn. This is appropriate for the initial visit for treatment of the corrosion.

• Ensure the documentation clearly states "chin" as the affected body part.
• Only use this code when the burn degree is truly unspecified; if a degree is documented, use the more specific code.
• The "A" at the end indicates an initial encounter for this condition.
