Exposure keratoconjunctivitis, right eye

This code signifies an inflammatory condition of the cornea and conjunctiva in the right eye, specifically caused by inadequate eyelid closure or exposure to environmental elements. This leads to drying and damage of the ocular surface.

Apply this code when documentation clearly indicates keratoconjunctivitis in the right eye resulting from exposure, such as in cases of lagophthalmos, facial nerve palsy, or proptosis. The physician's notes should specify the laterality and the etiology as exposure.

• Ensure documentation specifies "right eye" to support this laterality-specific code.
• Distinguish from other forms of keratoconjunctivitis (e.g., allergic, infectious) by confirming the exposure etiology.
• Consider co-reporting with codes for the underlying cause of the exposure (e.g., H02.211 for lagophthalmos, right eye).
