Carrier of other specified bacterial diseases

This code identifies an individual who harbors and can transmit a specific bacterial pathogen without currently exhibiting active symptoms of the disease. The individual acts as a reservoir for the bacteria, potentially infecting others, but is not acutely ill themselves.

Apply this code when documentation indicates a patient is a known carrier of a bacterial disease not otherwise specified, such as a chronic carrier of Streptococcus pneumoniae or Neisseria meningitidis based on laboratory findings. This is often used in public health surveillance or when screening contacts of infected individuals.

• Ensure the documentation clearly states "carrier" status and specifies the bacterial disease.
• Do not use this code for active infections; those require specific disease codes.
• This code is typically a secondary diagnosis, indicating a risk factor or public health concern.
