Acute miliary tuberculosis of a single specified site

This code signifies a severe, disseminated form of tuberculosis characterized by widespread small lesions (miliary) affecting a single, identified organ or anatomical location. It indicates an acute presentation of the infection, distinct from chronic or latent forms.

Apply this code when documentation clearly specifies acute miliary tuberculosis confined to a single site, such as the lung, kidney, or bone. This diagnosis typically arises from biopsy results, imaging findings, and positive mycobacterial cultures from the affected site.

• Ensure documentation explicitly states "acute" and "miliary" and specifies a single affected site.
• Do not use for disseminated miliary TB affecting multiple sites (refer to A19.1).
• Code also the specific site of involvement, if applicable and not inherently covered by the miliary designation.
