Corrosion of first degree of right ear, subsequent encounter

This code indicates a superficial burn, specifically a first-degree corrosion, affecting the outer part of the right ear, excluding the eardrum. This type of injury typically presents with redness and mild pain without blistering or skin breakage. The "subsequent encounter" designation signifies that the patient is receiving follow-up care for this previously treated injury.

Apply this code when a patient presents for ongoing management, such as wound checks, dressing changes, or medication refills, related to a first-degree corrosive burn on their right outer ear. This would be used after the initial treatment for the burn has already been provided and coded.

• Ensure the documentation clearly specifies a first-degree burn and that the injury is due to corrosion, not a thermal burn.
• Verify the laterality (right ear) and that the eardrum is not involved.
• Confirm that this is not the initial visit for this specific injury; otherwise, an "initial encounter" code would be more appropriate.
