Corrosion of second degree of chin, initial encounter

This code signifies a second-degree chemical burn affecting the chin area. It indicates damage extending through the epidermis and into the dermis, characterized by blistering, pain, and redness, resulting from exposure to a corrosive substance.

Apply this code when documenting a patient's initial presentation for a second-degree chemical injury specifically located on the chin. This includes cases where the patient is first seen for evaluation and treatment of this particular corrosion.

• Ensure the documentation clearly specifies a chemical burn (corrosion) rather than a thermal burn.
• Verify the burn depth is explicitly stated as "second degree" and the anatomical site as "chin."
• Confirm this is the initial encounter for treatment of this specific injury, not a subsequent visit.
