Oculoglandular listeriosis

This code describes a specific form of listeriosis characterized by inflammation of the eye and surrounding glandular structures. It is caused by the bacterium Listeria monocytogenes and typically presents with conjunctivitis, regional lymphadenopathy, and sometimes systemic symptoms.

Use this code when documentation clearly indicates a diagnosis of oculoglandular listeriosis, often presenting as Parinaud's oculoglandular syndrome. Supporting documentation should include microbiological confirmation of Listeria monocytogenes or a strong clinical suspicion with characteristic ocular and lymphatic involvement.

• Differentiate from other causes of oculoglandular syndrome, such as cat-scratch disease (A28.1) or tularemia (A21.2).
• Ensure the documentation specifies "oculoglandular" involvement to distinguish from other forms of listeriosis.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter.
