Z22.338
ICD-10-CMThis code indicates an individual who harbors streptococcal bacteria other than Group A or Group B, without exhibiting active symptoms or disease. The person is a carrier, meaning they can potentially transmit the bacteria to others, but are not currently infected themselves.
This code is appropriate for documenting asymptomatic carriage of various streptococcal species (e.g., Streptococcus pneumoniae, viridans streptococci) identified through laboratory testing, such as a positive culture, in the absence of clinical signs of infection. It would be used when a patient is found to be a carrier during screening or follow-up for exposure.
