Carrier of infectious disease. Includes colonization status and suspected carrier. Excludes2: carrier of viral hepatitis (B18.-)

Example 1: A patient is tested and found to be a carrier of methicillin-resistant Staphylococcus aureus (MRSA) but displays no symptoms. The patient is visiting their primary care physician for an annual check up., A healthcare worker is identified as a carrier of Neisseria meningitidis after a routine nasal swab. They are asymptomatic but may pose a risk of infection transmission., During a pre-surgical screening, a patient is found to have Streptococcus pyogenes in their throat, even without any signs of strep throat. This asymptomatic carrier status needs to be documented before surgery.

Documentation should include the specific infectious agent identified, the diagnostic method used for confirmation, and the absence or presence of symptoms. It's also essential to document the context of identifying the carrier status, such as during routine screening, contact tracing, or pre-operative evaluation.

** This code is used for individuals with a potential health hazard related to communicable diseases, rather than a current illness or injury.It helps track individuals who may not be sick but could transmit infectious diseases to others.
