Nonspecific reaction to test for tuberculosis
ICD-10 R76.1 is a billable code used to indicate a diagnosis of nonspecific reaction to test for tuberculosis.
R76.1 is used to classify a nonspecific reaction to a test for tuberculosis (TB), which may include a positive tuberculin skin test (TST) or interferon-gamma release assay (IGRA) without definitive evidence of active TB disease. This reaction indicates that the individual has been exposed to the TB bacteria, but it does not confirm active infection. The nonspecific nature of the reaction means that it could be due to prior vaccination (e.g., BCG vaccine), latent TB infection, or cross-reactivity with other mycobacterial infections. Clinicians must interpret these results in the context of the patient's clinical history, risk factors, and additional diagnostic tests to determine the appropriate management and follow-up. The presence of a nonspecific reaction necessitates further evaluation to rule out active TB disease and to assess the need for treatment or monitoring.
Detailed patient history, including risk factors for TB, vaccination status, and any symptoms suggestive of active TB.
Patients presenting with a positive TST or IGRA without active TB symptoms.
Consideration of the patient's immunocompromised status and potential for false-positive results.
Acute care notes should include the reason for TB testing, results, and any immediate management plans.
Patients with respiratory symptoms or recent exposure to TB who undergo testing in the emergency setting.
Rapid assessment of risk factors and potential need for isolation if active TB is suspected.
Used for screening patients for TB exposure.
Document the reason for the test, results, and any follow-up actions.
Internal medicine and infectious disease specialists should ensure thorough documentation of patient history.
R76.1 should be used when a patient has a nonspecific reaction to a TB test without evidence of active TB disease. It is essential to document the clinical context and any follow-up evaluations.
