Corrosion of first degree of right ear, initial encounter

This code signifies a superficial burn injury to the right ear, affecting only the outermost layer of skin (epidermis) and characterized by redness, mild swelling, and pain, but without blistering or deeper tissue damage. It specifically excludes injuries to the eardrum.

This code is appropriate for initial encounters where a patient presents with a first-degree corrosion (chemical burn) to any part of the right outer ear, such as the auricle or earlobe. Examples include exposure to mild acids or bases that cause only epidermal damage.

• Ensure the documentation clearly specifies "first degree" and "right ear" to support this code.
• Verify that the injury is a corrosion (chemical burn) and not a thermal burn, as different codes apply.
• Confirm this is the initial encounter for this specific injury; subsequent encounters will require a different seventh character.
