Carrier or suspected carrier of other venereal diseases

This code identifies an individual who is a known carrier or is suspected of being a carrier of a sexually transmitted infection (STI) other than those specifically classified elsewhere (e.g., HIV, syphilis, gonorrhea). It indicates the presence of the pathogen without necessarily exhibiting active disease symptoms.

This code is appropriate for documenting a patient who has tested positive for an STI but is asymptomatic, or for a patient who has been exposed to an STI and is being evaluated as a potential carrier. It can also be used for contact tracing purposes when a patient is identified as a source of infection for others.

• Always sequence this code after the definitive diagnosis of the specific STI, if known and active.
• Do not use this code for active, symptomatic STI infections; use the specific STI code instead.
• Consider using this code in conjunction with screening or exposure codes when applicable.
