Epidemic hemorrhagic conjunctivitis

This code represents an acute, highly contagious viral infection of the conjunctiva, characterized by sudden onset of redness, pain, tearing, and often subconjunctival hemorrhage. It is typically caused by enteroviruses, particularly coxsackievirus A24 variant and enterovirus 70, and can occur in outbreaks.

Use this code for documented cases of conjunctivitis specifically identified as epidemic hemorrhagic conjunctivitis, often during a recognized outbreak. Documentation should clearly indicate the characteristic hemorrhagic presentation and/or a confirmed viral etiology consistent with an epidemic strain.

• Differentiate from other forms of acute conjunctivitis; this code is specific to the epidemic hemorrhagic type.
• Ensure documentation specifies "epidemic" or "hemorrhagic" to support this specific diagnosis.
• Consider additional codes for any associated systemic symptoms if documented and clinically relevant.
