Acute pharyngitis due to other specified organisms

This code represents an acute inflammation of the pharynx caused by a bacterial, fungal, or parasitic organism other than those specifically classified elsewhere. It signifies a sudden onset of sore throat symptoms attributed to a pathogen that is identified but not a common viral or streptococcal etiology.

Apply this code when documentation specifies acute pharyngitis and identifies a causative organism that is not Strep, a common virus (like influenza or adenovirus), or one of the organisms listed in the Excludes1 notes. This often requires laboratory confirmation of the specific pathogen, such as Mycoplasma pneumoniae, Chlamydophila pneumoniae, or certain fungal infections.

• Ensure the documentation clearly states "acute" pharyngitis and specifies the "other" organism.
• Do not use this code if the organism is unknown; in such cases, an unspecified pharyngitis code would be more appropriate.
• Review Excludes1 notes carefully to avoid incorrect co-coding with conditions like gonococcal pharyngitis or pharyngitis due to infectious mononucleosis.
