Allergic dermatitis of right eye, unspecified eyelid

This code signifies an inflammatory reaction of the skin surrounding the right eye, specifically an unspecified eyelid, caused by an allergic response. This condition presents with symptoms such as redness, itching, swelling, and scaling of the affected eyelid.

Apply this code when documentation clearly indicates allergic dermatitis affecting the right eye, without specifying which eyelid (e.g., upper or lower). This diagnosis is typically supported by physician notes detailing an allergic reaction manifesting on the right eyelid, often after exposure to an allergen.

• Ensure the documentation specifies "allergic" dermatitis and laterality (right eye).
• Do not use this code if the specific eyelid (upper or lower) is documented; instead, use the more specific codes within the H01.11- series.
• Consider an external cause code if the allergen is identified and documented.
