2025 ICD-10-CM code Z20.1

Contact with and (suspected) exposure to tuberculosis.

This code should only be used when there is documented contact or suspected exposure to tuberculosis. It should not be used in isolation; additional codes should be used to represent any diagnosis, treatment, or other relevant findings.

Medical necessity is established by the patient's documented exposure to tuberculosis and the need for assessment and prevention of the disease.Guidelines for preventative treatment should be followed.

The clinical responsibility includes assessing the patient's risk of developing TB based on exposure history and performing appropriate screening tests such as tuberculin skin tests or interferon-gamma release assays (IGRAs).Treatment may include prophylactic antibiotics if indicated.

IMPORTANT:Consider using additional codes to specify the type of contact or the results of any testing performed.May be used with other ICD-10 codes depending on clinical circumstances.

In simple words: This code is used when someone has been near a person with tuberculosis or there's a chance they were exposed to it, whether or not they get sick.

This code classifies encounters for individuals who have had contact with or suspected exposure to tuberculosis (TB).It is used when a person is known to have been in proximity to a person with TB, or when there is a suspicion of exposure, regardless of whether the individual develops the disease.A corresponding procedure code should be used if a diagnostic test or preventative treatment is performed.

Example 1: A healthcare worker is exposed to a patient with confirmed pulmonary tuberculosis.Z20.1 is used to document the encounter for assessment and potential preventative therapy., A child living in a household with a recently diagnosed case of tuberculosis is brought in for testing. Z20.1 is used to document the encounter and any results., A patient presents to a clinic following travel to a region with a high incidence of tuberculosis.Z20.1 is used to document the encounter for evaluation and potential testing/treatment.

Details of the exposure, including the date, duration, and nature of contact with the source case.Results of any TB screening tests performed.Any treatment administered.
