Allergic dermatitis of left lower eyelid

This code signifies an inflammatory response of the left lower eyelid skin due to an allergic reaction. It presents as redness, itching, swelling, and sometimes blistering or scaling, specifically affecting the lower portion of the left eye.

Apply this code when documentation clearly indicates allergic contact dermatitis or atopic dermatitis affecting the left lower eyelid. Supporting documentation should specify the laterality (left) and the precise eyelid involved (lower).

• Ensure documentation differentiates allergic dermatitis from irritant contact dermatitis.
• Verify laterality and specific eyelid involvement; do not use for unspecified or bilateral cases.
• Consider an additional code for the specific allergen if identified and documented.
