Carrier or suspected carrier of typhoid

This code identifies an individual who is either asymptomatic but harbors Salmonella typhi (the bacterium causing typhoid fever) or is suspected of carrying the bacterium. These individuals can transmit the disease to others even without showing active symptoms themselves.

This code is appropriate for documenting a patient identified through public health screening as a typhoid carrier, or for individuals with a history of typhoid fever who continue to excrete the bacteria. It also applies to contacts of confirmed typhoid cases who are being investigated for carrier status.

• This code is for carrier status, not active typhoid fever. Active infection would be coded separately.
• Ensure documentation clearly supports either confirmed carrier status or strong suspicion based on clinical context or public health investigation.
• Consider any associated screening or laboratory tests that confirm the carrier state.
