The ICD10 Diagnosis List contains specific codes for a number of different bacteria, viruses, fungi/yeast, mycobacteria and miscellaneous types of organisms. The entire list can be found in category and subcategories:

Pathogens are coded as their own diagnosis codes:

Pathogens codes:

They are always entered as Combined ICD10 codes with an infection, but not all infections require pathogens. See Template:ICD10 Guideline Infection, Infections in ICD10 for more info.

Information about pathogens can be found in the patient's chart's Lab and culture reports; see that page for specific use instructions.

NOS pathogens

NOS vs Unknown in the context of pathogens

  • We must distinguish NOS from unknown.
    • NOS means that we do know the bug, but it's not in our list of specific pathogens
    • Infectious organism, unknown means we assume that there IS in fact a pathogen, but we have no idea about it's actual identity.
