Hemophilus influenzae infection, unspecified site

This code signifies an infection caused by Haemophilus influenzae where the specific anatomical location of the infection is not documented. It indicates the presence of this bacterial pathogen as the causative agent without further detail regarding the affected body system or organ.

Use this code when the medical record explicitly states a Haemophilus influenzae infection but provides no information about the site of infection. This is appropriate when the provider has confirmed the bacterial etiology but has not specified if it's pneumonia, meningitis, otitis media, or another localized infection.

• Avoid using this code if a more specific site of infection (e.g., pneumonia, meningitis) is documented; always code to the highest level of specificity.
• Query the provider if the documentation indicates a Haemophilus influenzae infection but omits the site, to allow for more precise coding.
• This code does not differentiate between encapsulated (e.g., Hib) and non-encapsulated strains.
