The ICD10 buglist 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 Infections in ICD10 for more info.

The Structure of the Pathogen List

  • There are categories for: Bacteria, Viruses, Fungi/Yeast, Mycobacteria, and Miscellaneous Organisms
  • In what comes below, we must distinguish NOS from unknown.
    • NOS means that we do know the bug, but it's not in our list of specific bugs
    • Unknown means we assume that there IS in fact a bug, but we have no idea about it's actual identity.
  • 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:

Old coding

The pathogens are a list of possible entries that make up the sub-code for diagnoses categorized as Infection.

Culture reports (old)

Follow up all culture reports up to 5 days after discharge from unit. If pathogen is still not available then, enter Unknown Pathogen.

Special Codes

Could someone please fill in specifics about how or when these are to be used? Specifically, if we know specific bugs, are there any that should be coded implicitly even if there are others (ie precedence rules)?

Coding when antibiotics are given but no cultures

If there is evidence of an ongoing infection, even if no further culture code the previous pathogen.

If no culture is sent then we choose the subcode No Culture Sent or Resulted
