Z22.4
ICD-10-CMCarrier of infections with a predominantly sexual mode of transmission
This code identifies an individual who is a known carrier of a sexually transmitted infection (STI) but is currently asymptomatic and not experiencing an active infection. It signifies the presence of the pathogen without active disease manifestation, indicating the potential for transmission.
This code is appropriate for documenting a patient who has tested positive for an STI pathogen, such as HIV, Hepatitis B, or Herpes Simplex Virus, but shows no current signs or symptoms of the disease. It is often used for public health tracking, partner notification, or when counseling patients on safe practices to prevent further transmission.
