2025 ICD-10-CM code A19
Miliary tuberculosis. This condition involves the spread of Mycobacterium tuberculosis throughout the body via the bloodstream, affecting multiple organs.
Medical necessity for services related to A19 is established by the diagnosis of miliary tuberculosis, confirmed through clinical findings, imaging, and microbiological tests.Treatment with antituberculosis medications is medically necessary to prevent serious complications and death.
Physicians diagnosing miliary tuberculosis consider symptoms such as fever, weight loss, cough, and night sweats.Physical exams may reveal enlarged lymph nodes, liver, or spleen.Diagnostic tests include chest X-rays, CT scans, blood cultures, and biopsies to identify the characteristic millet-seed-like lesions in affected organs.Treatment involves a prolonged course of antituberculosis medications and may require consultations with infectious disease specialists, pulmonologists, and other specialists depending on organ involvement.
In simple words: Miliary TB is a rare but serious type of tuberculosis (TB) that spreads throughout the body.It happens when TB bacteria get into the bloodstream and travel to different organs, forming tiny bumps like millet seeds. This can cause a range of symptoms like fever, weight loss, tiredness, and coughing. If not treated, it can be life-threatening.Treatment usually involves taking several antibiotics for many months.
Miliary tuberculosis is a disseminated form of tuberculosis that occurs when Mycobacterium tuberculosis spreads from the lungs to other parts of the body through the bloodstream. It is characterized by the formation of small, millet-seed-like lesions (tubercles) in multiple organs.Symptoms can vary depending on the organs involved but often include fever, weight loss, fatigue, cough, and night sweats. If left untreated, miliary tuberculosis can be fatal.Treatment typically involves a combination of antituberculosis medications for an extended period.
Example 1: A 30-year-old patient presents with persistent fever, weight loss, and a cough.Chest X-ray reveals miliary nodules.Sputum cultures and biopsies confirm miliary tuberculosis., An infant with a weakened immune system develops fever and difficulty breathing.Chest X-ray shows miliary patterns, and further tests confirm miliary tuberculosis., An older adult with a history of latent tuberculosis presents with fatigue, confusion, and low blood pressure.Imaging and laboratory tests reveal disseminated tuberculosis consistent with miliary TB.
Documentation for A19 should include clinical findings (fever, cough, weight loss, etc.), imaging results (chest x-ray, CT scan) showing miliary nodules, and microbiological confirmation (positive cultures or biopsies) of Mycobacterium tuberculosis in affected organs.Additional documentation may be needed depending on the specific organ involvement (e.g., neurological exam findings for meningitis, liver function tests for hepatic involvement).
