Acute pharyngitis, unspecified

This code signifies an acute inflammation of the pharynx, commonly known as a sore throat, without further specification of the causative agent. It represents a sudden onset of pharyngeal discomfort, often accompanied by pain, difficulty swallowing, and redness of the throat.

Apply this code when documentation indicates an acute pharyngitis but lacks specific details regarding the etiology (e.g., bacterial, viral, streptococcal). This is appropriate for cases where the provider has not identified a specific pathogen or when the diagnostic workup is incomplete or negative for specific causes.

• Do not use this code if a specific infectious agent (e.g., streptococcus, influenza) is documented; instead, code to the specific organism.
• Review documentation for terms like "sore throat," "pharyngitis," or "acute pharyngitis" without further qualification.
• Be mindful of the Excludes1 note; never code this with influenza with other respiratory manifestations.
