Chemical burn of eyelids and periocular area

This code signifies tissue damage to the eyelids and the surrounding area of the eye caused by exposure to a chemical substance. This injury can range from superficial irritation to deep tissue necrosis, affecting the delicate structures of the eye and adnexa.

Apply this code when documentation specifies a chemical burn affecting the eyelids, canthi, or periorbital skin. This includes injuries from acids, alkalis, solvents, or other corrosive agents. Supporting documentation should clearly state the chemical nature of the burn and its anatomical location.

• Differentiate from thermal burns of the same area; this code is exclusively for chemical etiology.
• Always sequence this code first if it represents the primary reason for the encounter.
• Look for additional codes to specify the type of chemical (e.g., external cause codes) and the severity or extent of the burn, if documented.
