2025 ICD-10-CM code A19.0
(Active) Effective Date: N/A Infectious and Parasitic Diseases - Miliary tuberculosis Certain infectious and parasitic diseases (A00-B99) Feed
Acute miliary tuberculosis affecting a single specific site in the body.
Medical necessity is established by the presence of active, symptomatic miliary tuberculosis requiring treatment to prevent further dissemination and organ damage.The affected site should be clearly documented.
Diagnosis involves patient history, physical examination, imaging (X-ray, CT, MRI), and laboratory tests (tuberculin skin test, CSF analysis). Treatment typically requires a multi-drug regimen including isoniazid, rifampin, pyrazinamide, and ethambutol.
In simple words: This is a severe form of tuberculosis (TB) that spreads through the bloodstream and affects one particular organ in the body.
Acute miliary tuberculosis is a rare, disseminated form of tuberculosis where small tubercles form in multiple organs due to the spread of Mycobacterium tuberculosis via the bloodstream.This code specifies that the miliary tuberculosis is acute and involves only one site.
Example 1: A patient presents with fever, headache, and altered mental status.A chest X-ray reveals miliary pattern, and subsequent MRI shows a single tuberculoma in the brain, confirming a diagnosis of acute miliary tuberculosis of the brain., A patient with a history of pulmonary tuberculosis develops acute onset of right upper quadrant pain and hepatomegaly. Imaging reveals multiple small lesions within the liver consistent with miliary tuberculosis, but no other organ involvement is found., A child with persistent fever and weight loss is found to have splenomegaly and a positive tuberculin skin test. Further investigations reveal miliary tuberculosis isolated to the spleen.
Documentation should include evidence of active tuberculosis infection, such as positive cultures, imaging findings (e.g., miliary pattern on chest X-ray, granulomas on CT/MRI), and clinical symptoms.Specificity of the single affected site is crucial for accurate coding.
** Distinguishing A19.0 from A19.1 (multiple sites) and other forms of tuberculosis is crucial for accurate reporting.
