Corrosion of third degree of unspecified ear, subs encntr

This code signifies a third-degree burn, also known as a full-thickness burn, affecting any part of the external ear, excluding the eardrum. These severe injuries involve destruction of the epidermis and dermis, extending into subcutaneous tissue, and often present with a leathery, waxy, or charred appearance.

Apply this code for follow-up encounters, such as wound care, debridement, or skin grafting, for a previously diagnosed third-degree corrosion of the ear. It is appropriate when the patient is receiving active treatment for the acute effects of the burn, but not for the initial injury or for sequelae.

• Ensure the documentation clearly specifies a third-degree burn and identifies the ear as the affected site, excluding the eardrum.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is still receiving active treatment for the burn.
• Do not use this code for initial treatment of the burn; refer to codes with an "A" seventh character for initial encounters.
