Corrosion of second degree of buttock, initial encounter

This code signifies a second-degree burn, specifically a corrosion, affecting the buttock area. A second-degree burn involves damage to the epidermis and dermis, characterized by blistering, pain, and redness. Corrosion indicates the injury was caused by a chemical agent.

Apply this code for a patient presenting with a chemical burn to the buttock that has resulted in blistering and partial-thickness skin damage. This code is appropriate for the initial treatment of such an injury, indicating the patient is receiving active care for the burn.

• Ensure the documentation clearly specifies a chemical etiology for the burn to use "corrosion" rather than "burn."
• Verify the depth of the burn is explicitly stated as second-degree or partial-thickness.
• Confirm this is the initial encounter for this specific injury; subsequent encounters will require a different seventh character.
