Epidemic keratoconjunctivitis

This code represents an acute, highly contagious viral infection of the conjunctiva and cornea, typically caused by adenoviruses. It is characterized by sudden onset of red, watery eyes, foreign body sensation, photophobia, and often preauricular lymphadenopathy. Corneal involvement can lead to subepithelial infiltrates and temporary vision impairment.

Use this code for documented cases of epidemic keratoconjunctivitis, often presenting in outbreaks. The diagnosis is typically made clinically based on characteristic signs and symptoms, sometimes confirmed by viral culture or PCR. Documentation should clearly indicate both conjunctival and corneal involvement.

• Differentiate from other forms of conjunctivitis (e.g., bacterial, allergic) which have distinct codes.
• Ensure documentation specifies "epidemic" or viral etiology consistent with adenovirus infection.
• Consider sequencing if other ocular conditions or systemic viral infections are also present.
