Eczematous dermatitis of right upper eyelid

This code signifies an inflammatory skin condition affecting the right upper eyelid, characterized by redness, itching, scaling, and sometimes blistering or weeping. It represents a form of contact dermatitis or atopic dermatitis specifically localized to this ocular adnexa.

Apply this code when documentation clearly specifies eczematous changes on the patient's right upper eyelid. This is appropriate for conditions like allergic contact dermatitis, irritant contact dermatitis, or atopic dermatitis manifesting on this specific anatomical site. Supporting documentation should include the laterality and the specific eyelid involved.

• Ensure documentation specifies "right" upper eyelid; otherwise, an unspecified laterality code may be more appropriate.
• Distinguish from other eyelid inflammations like blepharitis (H01.0-) or hordeolum/chalazion (H00.-).
• If the cause of the eczematous dermatitis is known (e.g., allergic contact), consider an additional code from Chapter 20 (External Causes of Morbidity) to identify the allergen.
