Contact blepharoconjunctivitis, right eye

This code describes inflammation of both the eyelid and the conjunctiva in the right eye, specifically caused by contact with an irritant or allergen. It signifies a localized allergic or irritant reaction affecting these ocular structures.

Apply this code when documentation clearly indicates blepharoconjunctivitis in the right eye resulting from external contact. This includes reactions to cosmetics, airborne allergens, or topical ophthalmic medications. Supporting documentation should specify the laterality and the contact etiology.

• Ensure documentation specifies "right eye" to support laterality.
• Distinguish from other forms of blepharoconjunctivitis (e.g., H10.52- for left eye, H10.51- for bilateral) and non-contact etiologies.
• Consider an additional code for the specific allergen or irritant if known and documented (e.g., T49.3X5A for adverse effect of ophthalmic preparations).
