Acute epidemic hemorrhagic conjunctivitis (enteroviral)

This code signifies an acute, highly contagious form of conjunctivitis characterized by sudden onset, redness, swelling, and often subconjunctival hemorrhage. It is specifically caused by an enterovirus, leading to rapid spread within communities. Patients typically present with severe eye pain, photophobia, and watery discharge.

Apply this code when documentation clearly indicates a diagnosis of acute epidemic hemorrhagic conjunctivitis with an identified or suspected enteroviral etiology. This diagnosis is often made clinically based on the characteristic presentation during an outbreak. Supporting documentation should include physician notes detailing the acute onset, hemorrhagic features, and epidemiological context.

• Ensure documentation specifies "epidemic" and "hemorrhagic" to differentiate from other forms of acute conjunctivitis.
• Do not use for non-epidemic or non-hemorrhagic viral conjunctivitis, which would be coded elsewhere.
• Consider an additional code for any associated systemic symptoms if documented and clinically significant.
