Influenza in ICD10

Additional Info

• There are 3 influenza-specific codes.
• These two codes do double-duty:
  • Influenza virus, avian (bird flu)
  • Influenza virus, other than avian
  • When combined with Influenza without pneumonia they identify influenza pneumonia.
  • Similarly they can be used to identify the organism to go along with any of:
    • Upper respiratory infection, acute NOS
    • Sinusitis, acute
    • Pharyngitis, acute
    • Tonsillitis, acute
    • Laryngitis or tracheitis, acute
    • Epiglotittis, acute

Alternate ICD10s to consider coding instead or in addition

• Pneumonia, viral
