Corrosion of second degree of right ear, initial encounter

This code signifies a second-degree chemical burn affecting the external structures of the right ear, excluding the eardrum. A second-degree corrosion involves blistering, partial-thickness skin damage, and significant pain, resulting from contact with a corrosive substance.

Apply this code when documenting the initial treatment for a patient presenting with a chemical burn to the right outer ear, characterized by blistering and partial skin destruction. This would be used for the first encounter for this specific injury.

• Ensure the documentation clearly specifies "corrosion" (chemical burn) rather than a thermal burn.
• Verify the degree of the burn is explicitly stated as "second degree" and the location is the "right ear."
• Confirm this is the patient's initial encounter for this specific injury; subsequent encounters would require a different seventh character.
