Herpesviral conjunctivitis

This code signifies an inflammation of the conjunctiva caused by a herpesvirus infection. It typically presents with redness, irritation, and discharge in one or both eyes, often accompanied by characteristic vesicular lesions on the eyelids or periorbital area. The infection can be primary or recurrent.

Use this code when documentation clearly indicates a diagnosis of conjunctivitis specifically attributed to a herpesvirus. This diagnosis is often made clinically based on characteristic signs and symptoms, and may be supported by laboratory confirmation (e.g., viral culture, PCR) or a history of recurrent herpes simplex infections.

• Differentiate from other forms of viral conjunctivitis; only use for herpesviral etiology.
• Specify laterality if documented (e.g., right, left, bilateral) using additional codes if available for laterality.
• Ensure documentation supports the viral cause, not just "conjunctivitis."
