ICD-10 Code A19.8 – Other miliary tuberculosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A19.8 – Other miliary tuberculosis
What it is
A19.8 identifies miliary tuberculosis that does not fit a more specific subtype. Use it for disseminated tuberculosis when documentation states “other miliary tuberculosis” or an equivalent term.
Clinical signs
Clinical features vary; refer to documentation. Miliary tuberculosis generally reflects widespread TB infection with systemic illness and multiple organ involvement, but the record must support the “other” designation.
When to use this code
Use A19.8 when the provider documents other miliary tuberculosis and does not specify a different miliary TB type. It may also apply when the note clearly describes disseminated TB but leaves the form unspecified. Check documentation if the record only says tuberculosis without miliary involvement.
Do not use for
Do not use this code for pulmonary tuberculosis, latent TB, or ordinary active TB without miliary spread. If the chart names a more specific miliary tuberculosis code, report that code instead.
Coding tip
Code the exact documented TB type; if “miliary” is not stated, verify the provider’s wording before assigning A19.8.
