Pharyngoconjunctival fever

This code identifies an acute viral infection characterized by inflammation of both the pharynx (throat) and conjunctiva (the membrane lining the eyelids and covering the white part of the eye). It is typically caused by adenoviruses and presents with symptoms such as sore throat, fever, and red, watery eyes.

Apply this code when documentation clearly indicates a diagnosis of pharyngoconjunctival fever, often seen in outbreaks in schools or camps. Supporting documentation should include clinical findings consistent with both pharyngitis and conjunctivitis, along with systemic symptoms like fever.

• Ensure documentation specifies involvement of both the pharynx and conjunctiva; if only one is affected, a more specific code for pharyngitis or conjunctivitis should be used.
• Do not use this code for bacterial conjunctivitis or pharyngitis; differentiate based on clinical presentation and, if available, lab results.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter.
