The '''pathogens''' are a list of possible entries that make up the sub-code for diagnoses categorized as [[Infections]].
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 drawn from the '''[[S_Pathogens]]''' table on your PDA and in the [[CCMDB.mdb]].
{{subcat collapsible|supercategory = Pathogens}}


== Pathogen Table ==
Pathogens are coded as their own diagnosis codes:
*For the most up-to-date list of pathogens, see your PDA or Diagnosis code book.  This is the list as of May 08 and for orientation only.
{{ListICD10Category | categoryName = Pathogens}}


'''*will update this list with a table.''' (trish pending)
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.

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

***g+ve = gram positive
*In each of those categories there are a number of specific bugs with their own codes (e.g. B95.3 is Strep pneumoniae)
***R = Rod
*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:
***C = coccus
**[[Bacteria, NOS]]
**[[Virus, NOS]]
**[[Fungus or yeast, NOS]]
**[[Nontuberculous mycobacteria]]
**[[Other type of infectious organism, NOS]]

***AFB is defined as Acid Fast Bacilli, which is a laboratory test used to identify certain types of bacteria such as mycobacteria that cause TB.  There was a question from data collectors about how to capture this sputum sample.  I guess the fact that the sputum sample is used to categorize the pathogen is why the discussion was placed here.--[[User:JHutton|JHutton]] 12:49, 11 August 2008 (CDT)

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

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.
