Infections in ICD10 are coded somewhat inconsistently. There are #Diagnoses where the pathogen is implied and #Diagnoses where the pathogen must be coded separately. #Coding Antibiotic Resistance should also be done when there is one.

Dx_Date infections in Acquired Diagnosis / Complication

  • The date we want to use is the date in which the infection first appeared clinically. This can be a very difficult determination, and may include consideration of:
    • Date on which the clinical signs or symptoms first appeared (e.g. fever, or dysuria, etc)
    • Date on which the culture was sent --- but this can be misleading because a culture may not be sent until several days after the symptoms appear.
    • Thus, as usual, you must use your clinical judgment to decide when the infection first showed up.

Untreated positive cultures

  • Probably the most common of these is urine and sputum.
  • How to code these depends on what the clinical team thinks is true:
    • If they're not treating because they think it's NOT an infection and instead is colonization, then code it as one or the other of: Colonized with organism (not infected) and/or something like Urine tests, NOS, abnormal
    • If on the other hand, they just failed (permanently, or temporarily) to treat what became apparent later to be a real infection, then code it as an infection.
