Corrosion of first degree of unspecified ear, init encntr

This code signifies a superficial chemical burn to the outer ear, excluding the eardrum, that presents as redness without blistering or skin loss. It indicates damage limited to the epidermis, caused by contact with a corrosive substance.

Apply this code when a patient presents with a first-degree chemical burn to any part of the external ear, such as the auricle or earlobe, and it is the initial treatment for the injury. This would include exposure to mild acids, bases, or other irritants resulting in erythema.

• Ensure the documentation specifies "first degree" and "corrosion" (chemical burn) to the ear.
• Verify that the burn location is described as the external ear, excluding the tympanic membrane.
• Confirm this is the initial encounter for this specific injury; subsequent encounters will require a different seventh character.
