ICD-10-CM Code for Nonspecific reaction to tuberculin skin test without active tuberculosis R76. 11.
A diagnosis of latent TB infection is made if a person has a positive TB test result and a medical evaluation does not indicate TB disease. The decision about treatment for latent TB infection will be based on a person's chances of developing TB disease by considering their risk factors.
Persons with latent TB infection do not feel sick and do not have any symptoms. They are infected with M. tuberculosis, but do not have TB disease. The only sign of TB infection is a positive reaction to the tuberculin skin test or TB blood test.
Your tests show that you have latent TB infection, also referred to as "LTBI." Latent TB infection means TB germs are in your body but it is like the germs are sleeping. The latent TB germs are not hurting you and cannot spread to other people. If the TB germs wake up and become active, they can make you sick.
If you are a provider that has administered a Tuberculin Skin Test (TST) or an Interferon Gamma Release Assay (IGRA) where the result was positive, you must complete a Latent Tuberculosis Infection reporting form.
TB is a notifiable disease, meaning that clinicians have a statutory duty to notify local authorities or a local Public Health England centre of suspected cases, and efforts have been made to strengthen services and ensure clear lines of accountability and responsibility.

In active tuberculosis, the bacteria multiply in the body, causing noticeable symptoms. This is also when the disease can spread to others. The difference between active and latent TB is the amount of organisms in the body, according to Dr. Reichman.
The main ways to diagnose LTBI are by placing a tuberculin skin test (TST) on the forearm or by getting a TB blood test, in addition to obtaining a chest radiograph (x-ray) if either one of these tests is positive. One-third of the world's population has LTBI. The TB germs are dormant (asleep) in the body.
Tuberculosis is a bacterial infection that usually infects the lungs. It may also affect the kidneys, spine, and brain. Being infected with the TB bacterium is not the same as having active tuberculosis disease. There are 3 stages of TB—exposure, latent, and active disease.
The recommended 2020 LTBI treatment guidelines include three preferred rifamycin-based regimens and two alternative daily-isoniazid monotherapy regimens. These recommendations are intended for Mycobacterium tuberculosis infections with presumed susceptibility to isoniazid or rifampin.
Latent infection, generally speaking, means the residence in the body of a specific infectious agent without any manifest symptoms. The symptomless incubation period, which in certain diseases, notably measles and smallpox, is fairly definite in length, is a period of latency in infection.

A person who has been exposed to TB bacteria may become infected. A person with latent TB infection (LTBI) cannot spread the bacteria to others right away. Only those who develop active TB disease can spread the bacteria to others.
However, latent TB bacteria can 'wake up' and become active in the future, making you ill. This can happen many years after you first breathe in TB bacteria. Latent TB bacteria are more likely to wake up if you experience lifestyle stresses or other illnesses that weaken your immune system.
After exposure, it usually takes 8 to 10 weeks before the TB test would show if someone had become infected." "Depending on ventilation and other factors, these tiny droplets [from the person who has active tuberculosis] can remain suspended in the air for several hours.
