Allergic dermatitis of unspecified eye, unspecified eyelid

This code signifies inflammation of the eyelid due to an allergic reaction, where the specific eye (left or right) and the precise eyelid (upper or lower) are not documented. It indicates an immune response to an allergen manifesting as dermatitis affecting the periocular region.

Apply this code when documentation confirms allergic dermatitis of an eyelid, but the medical record does not specify which eye or which eyelid is affected. This is appropriate for initial encounters where laterality and specific eyelid involvement are not yet determined or clearly recorded.

• Avoid using this code if laterality (left/right) or specific eyelid (upper/lower) is documented; instead, use a more specific code from the H01.11- subcategory.
• Ensure the documentation explicitly states "allergic dermatitis" or a similar allergic inflammatory process of the eyelid.
• Consider querying the provider for more specific anatomical detail if available to allow for more precise coding.
