Additional Info

This code indicates only what it says, colonized BUT NOT INFECTED, with an organism. Do not use this code if there is an actual infection (symptomatic or not), for those use the proper infection code.
If present on admission, code as a Comorbid Diagnosis, not as an Admit Diagnosis. If applicable, still code Isolation, infectious in CCI Picklist .
We are only tracking colonization with the following organisms that infection prevention and control is interested in:
- MRSA
There ARE lots of other bugs that can colonize various parts of the body, almost all of which CAN also cause infection. There is a smallish list of bugs that NEVER colonize and are always believed to be active infectious agent, e.g. Mycobacterium TB, Legionella, ebola.

Colonization

You can use the "set MRSA Colonized" button to enter the following:

Combined code the following as a Comorbid Diagnosis (not as an Admit Diagnosis.
Enter CCI Picklist Isolation, infectious, likely as Acquired Procedure, but consult Admit Procedure/Acquired Procedure to be sure.

Infection

Combined code the following

the appropriate code from one of the following

Colonized vs local infection

If MRSA drawn from an abscess or deep in wound and you think it is causing the "local" infection, else code colonization.
