Pathogens

The pathogens are a list of possible entries that make up the sub-code for diagnoses categorized as Infection. Also referred to as: UPL, Universal Pathogen List. Pathogens are drawn from the S_Pathogens table on your PDA and in the CCMDB.mdb.

Pathogen Table

• 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.

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

Discussion

Can someone confirm for me again when it is appropriate to use code 59 from pathogen table?--MWaschuk 18:25, 2 March 2009 (CST)

Fungi

Aspergillus species Blastomyces, Candida, Crytococcus, Histoplasma

Virus

Adenoviruses, Cytomegaloviruses, Epstein-Barr virus, Herpes simplex, Herpes zoster, West Nile

Parasites

Cryptosporidium, Giardia Lamblia, Malaria, Pneumocystis carinii (PCP), Toxoplasma gondii

Data Integrity Rules

The CCMDB.mdb runs checks for the following:

• no infections without pathogens
• no non-infections with pathogens

For details, see the coding in Access.

Discussion

• Sputums for AFB (Acid Fast Bacilli). As per Dr. Kumar: a negative AFB culture is considered a negative culture and should not to be coded as NO C&S culture sent.--FLindell 15:33, 6 August 2008 (CDT)
  • Fran, what's an AFB, and how does this entry relate to the pathogens? Can you give a little more detail? Thanks--Ttenbergen 16:09, 6 August 2008 (CDT)
    • 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.--JHutton 12:49, 11 August 2008 (CDT)

• How do we code scabies ?cellulitis other parasite? Please let me know ThanksSKiesman 13:30, 17 November 2008 (CST)
  • Don't code. We haven't been tracking incidence of scabies nor are we going to start. TOstryzniuk 21:21, 17 November 2008 (CST)

• Can someone confirm for me again when it is appropriate to use code 59 form pathogen table (aspiration-early presentation with documentation). Many times it occurs where the pt is in respiratory distress and requires urgent intubation and because there LOC was decreased prior to intubation the physician will document that the pt likely aspirated and cxr will show a new infiltrate or the like. The ETT sample may or may not detect a pathogen. Is this a HAP with subcode 59 or is this a HAP with subcode pathogen detected or negative culture.--MWaschuk 11:26, 16 March 2009 (CDT)

• Mary-Lou, this topic was discussed with Dan Roberts at a previous meeting. He told us to code HAP or CAP with a subcode of aspiration, if this is known, as the admission code. Then if the patient subsequently has an organism, we are to code this as a complication (eg. HAP with subcode the organism.) Let me know if you have any other questions about this. --LKolesar 13:11, 16 March 2009 (CDT)
