Carrier of other Enterobacterales

This code identifies an individual who harbors a strain of Enterobacterales, a broad family of gram-negative bacteria, without exhibiting active symptoms of infection. The individual acts as a reservoir for the bacteria, potentially capable of transmitting it to others. This status is typically confirmed through laboratory testing, such as culture or PCR.

Apply this code when documentation indicates a patient is an asymptomatic carrier of an Enterobacterales species other than those specifically classified elsewhere (e.g., Salmonella, Shigella, E. coli O157:H7). This often arises in public health screenings, contact tracing, or follow-up after a resolved infection where the organism persists. It is also relevant for healthcare workers or food handlers identified as carriers.

• Ensure the documentation clearly states "carrier" or "asymptomatic colonization" and specifies an Enterobacterales species not covered by more specific Z22 codes.
• Do not use this code if the patient has an active infection; instead, code the specific infection.
• Consider any associated risk factors or reasons for screening, which may require additional codes.
