Corrosion of third degree of right ear, initial encounter

This code signifies a full-thickness tissue injury to the right ear, excluding the tympanic membrane, caused by corrosive substances. It indicates severe damage extending through all layers of the skin and potentially into underlying tissues. This is the initial encounter for this specific injury.

Apply this code when documentation clearly states a third-degree corrosive burn to any part of the right ear, such as the auricle or external auditory canal, but not the eardrum. This is appropriate for the first time the patient is seen for this particular injury.

• Ensure documentation specifies "third degree" and "corrosion" for the ear.
• Verify laterality (right ear) and exclude tympanic membrane involvement.
• Confirm this is the "initial encounter" for the injury; subsequent care would use a different seventh character.
