Allergic dermatitis of right upper eyelid

This code signifies an inflammatory skin reaction affecting the upper eyelid of the right eye, specifically caused by an allergic response. This condition typically presents with redness, itching, swelling, and sometimes scaling or blistering of the eyelid skin due to contact with an allergen.

Use this code when documentation clearly indicates allergic dermatitis affecting the right upper eyelid. This diagnosis is supported by physician notes detailing an allergic reaction, such as contact dermatitis, localized to the specified anatomical site.

• Differentiate from non-allergic inflammatory conditions of the eyelid, such as blepharitis or simple irritant dermatitis.
• Ensure laterality (right) and eyelid specificity (upper) are explicitly documented.
• Consider an additional code for the causative allergen if identified and documented.
