Allergic dermatitis of left upper eyelid

This code signifies an inflammatory reaction of the skin on the left upper eyelid due to an allergic response. It presents with symptoms such as redness, itching, swelling, and possibly scaling or blistering, specifically affecting the superior portion of the left eye's protective covering.

Apply this code when documentation clearly indicates an allergic etiology for dermatitis localized to the left upper eyelid. This typically occurs following exposure to an allergen, such as cosmetics, environmental irritants, or topical medications. Supporting documentation should specify "allergic dermatitis" and "left upper eyelid."

• Ensure the documentation differentiates between irritant contact dermatitis and allergic contact dermatitis.
• Verify laterality (left) and specific eyelid (upper) are clearly stated in the medical record.
• Consider an additional code for the specific allergen if identified and documented.
