Contact blepharoconjunctivitis, unspecified eye

This code signifies inflammation of both the eyelid margins (blepharitis) and the conjunctiva (conjunctivitis) due to contact with an irritant or allergen. It represents a general diagnosis when the specific irritant or allergen is unknown, and the affected eye is not specified.

Apply this code when documentation indicates blepharoconjunctivitis caused by contact, but the laterality (right, left, or bilateral) is not recorded, and the specific causative agent is not identified. This is often used for initial presentations where further investigation is pending.

• Avoid using this code if the laterality is documented; instead, choose the more specific H10.531 (right), H10.532 (left), or H10.533 (bilateral).
• Do not use this code if the specific contact allergen or irritant is known; instead, code the specific type of allergic or irritant conjunctivitis.
• This code should be considered a less specific option and should be avoided if more detailed information is available in the medical record.
