Corrosion of unsp degree of unspecified ear, init encntr

This code signifies damage to any part of the external or middle ear, excluding the eardrum, caused by a corrosive substance. The severity of the corrosion is not specified, and this code is used for the initial treatment of the injury.

Apply this code when a patient presents for the first time with a chemical burn to an unspecified part of the ear (e.g., auricle, external auditory canal) where the degree of the burn is not documented. This would include scenarios where a corrosive liquid or gas has come into contact with the ear, causing tissue damage.

• Ensure the documentation clearly states "corrosion" or "chemical burn" to the ear, not a thermal burn.
• Only use this code for the initial encounter for treatment of the injury. Subsequent care will require a different seventh character.
• If the specific degree of corrosion (e.g., first, second, third degree) is known, a more specific code should be selected.
