They are always entered as [[Combined ICD10 codes]] with an [[Infections in ICD10|infection]], but not all infections require pathogens. See [[Template:ICD10 Guideline Infection]], [[Infections in ICD10]] for more info.
Follow up all culture reports up to 5 days after discharge from unit. If pathogen is still not available then, enter [[Unknown Pathogen]].

*In each of those categories there are a number of specific bugs with their own codes (e.g. B95.3 is Strep pneumoniae)
*But obviously we can't list every bug of any type, so for each of those categories there is also a "wastebasket" code for "NOS". For example, if the bug is a specific bacteria but it's not in our list, then use [[Bacteria, NOS]], etc.  These are:
**[[Bacteria, NOS]]
**[[Virus, NOS]]
**[[Fungus or yeast, NOS]]
**[[Nontuberculous mycobacteria]]
**[[Other type of infectious organism, NOS]]

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.
