Additional Info
- Infectious mononucleosis (IM, mono), also known as glandular fever, is an infection usually but not always caused by the Epstein–Barr virus (EBV). While usually caused by Epstein–Barr virus (EBV), also known as human herpesvirus 4, which is a member of the herpes virus family, a few other viruses may also cause the disease.
- This code is NOT a "buglist" code because it can be caused by various viruses, and usually the causative bug is never identified, or even sought in clinical Mononucleosis.
- Thus, for this diagnosis, since we do not have a specific bug code for EBV, do the following:
- If the virus IS known and is on our list of specific bug list viruses, use that.
- If the virus IS known and is NOT on our list of specific bug list viruses, use Virus, NOS -- this is the current situation for EBV, by the way.
- If the virus is NOT known, use Infectious organism, unknown
- Thus, for this diagnosis, since we do not have a specific bug code for EBV, do the following:

Infections
Infections in ICD10 have combined coding requirements for some of their pathogens. Any that have antibiotic resistances would store those as Combined ICD10 codes as well. If the infection is acquired in the hospital, see Nosocomial infection, NOS. See Lab and culture reports for confirmation and details about tests. See Infections in ICD10 for more general info.
Possible Simultaneous Presence of Multiple Different Types of Infection in a Single Site
- This refers to the situation where there may be simultaneous infection with multiple types of organisms -- e.g. 2 of bacteria, virus, fungus. While a classic example is a proven viral pneumonia (e.g. influenza) with a suspected/possible bacterial pneumonia superimposed, this kind of thing can occur in places other than the lungs, e.g. meningitis.
- The "signature" of this is typically the patient being treated simultaneously with antimicrobial agents for multiple types of organisms. BUT don't confuse this with there being infections at DIFFERENT body sites.
- As per our usual practice, we will consider a diagnosis as present if the clinical team thinks it's present and are treating it, with the exception that the team initially treated for the possible 2nd type of infection but then decided it likely was NOT present and stopped those agents.
- And remember that Infectious organism, unknown is used when the the specific organism is unknown (this could be not knowing the TYPE of organism, or suspecting the type but not having identified the specific organism of that type), while when the organism has been identified but it's not in our bug list, THEN use Bacteria, NOS, Virus, NOS or Fungus or yeast, NOS.
