Measles keratitis and keratoconjunctivitis

This code signifies inflammation of the cornea and/or conjunctiva specifically caused by the measles virus. It represents an ocular complication of a measles infection, characterized by symptoms such as eye redness, pain, light sensitivity, and vision changes.

Use this code when documentation clearly states a diagnosis of keratitis or keratoconjunctivitis directly attributed to a measles infection. This typically occurs in patients presenting with measles who develop ophthalmic manifestations.

• Always sequence the measles infection code (B05.-) first, followed by this code as a manifestation.
• Ensure documentation specifies "measles" as the etiology of the keratitis/keratoconjunctivitis to differentiate from other infectious causes.
• Do not use this code for other forms of viral keratitis or keratoconjunctivitis not explicitly linked to measles.
