Miliary tuberculosis (A19)

The ICD-10 code A19 and its subcategories are specifically used to classify cases of miliary tuberculosis, a severe form of tuberculosis characterized by tiny lesions spread throughout the body. These codes differentiate between acute and chronic forms, as well as specify whether the disease affects one site, multiple sites, or remains unspecified.

The term miliary tuberculosis is also known by various synonyms such as disseminated tuberculosis, acute miliary tuberculosis, and chronic granulomatous tuberculosis, helping healthcare providers accurately identify cases when searching for the ICD-10 code for miliary tuberculosis. For example, A19.0 is used when acute miliary tuberculosis involves a single site, while A19.1 applies to multiple sites. A19.2 and A19.9 cover unspecified cases, with A19.8 addressing other or chronic forms. Recognizing these codes ensures proper documentation and aids in distinguishing between different presentations of this disseminated infectious disease.
