Corrosion of second degree of left ear, subsequent encounter

This code signifies a second-degree chemical burn affecting any part of the left ear, excluding the eardrum, during a follow-up visit. A second-degree corrosion indicates damage extending beyond the epidermis into the dermis, characterized by blistering, pain, and redness.

Apply this code when a patient presents for ongoing treatment, evaluation, or management of a previously diagnosed second-degree chemical burn to their left ear. This includes situations like wound care, infection checks, or assessment of healing progress after the initial injury.

• Ensure the documentation clearly specifies "left ear" and "second degree" corrosion.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing phase.
• Differentiate from initial encounters (A) or sequela (S) based on the patient's current stage of care.
