Carrier of other infectious diseases

This code identifies an individual who harbors a pathogenic organism for an infectious disease but does not exhibit active symptoms or signs of the illness. The individual can transmit the disease to others, acting as a reservoir for the infection.

Use this code when documenting a patient identified as a carrier of a specified infectious disease, such as a chronic carrier of Hepatitis B or a healthy carrier of Salmonella, without currently experiencing an acute infection. This is often identified through screening or contact tracing.

• Always code the specific infectious disease as a secondary diagnosis, if known.
• Do not use this code for individuals with active infections; use the specific disease code instead.
• Ensure documentation clearly states the patient is a "carrier" and not merely exposed or at risk.
