Other miliary tuberculosis

This code represents a disseminated form of tuberculosis where the infection has spread from the primary site to multiple organs via the bloodstream, forming numerous small (1-5 mm) lesions resembling millet seeds. It signifies a systemic manifestation of Mycobacterium tuberculosis infection that doesn't fit the criteria for specific organ involvement or unspecified miliary tuberculosis.

Use this code when documentation specifies miliary tuberculosis affecting multiple sites or systems, but the specific organs involved are not explicitly detailed or do not have a more precise miliary tuberculosis code. This applies when the physician's diagnosis clearly states "other miliary tuberculosis" or provides clinical evidence of widespread dissemination without further specificity.

• Ensure the documentation clearly distinguishes "other miliary" from "unspecified miliary" (A19.9) or miliary TB affecting a specific organ (e.g., A19.0, A19.1).
• Always sequence this code after the underlying cause of the miliary tuberculosis, if known and separately reportable.
• Look for terms like "disseminated TB," "generalized TB," or "systemic TB" with miliary features when specific organ involvement isn't coded elsewhere.
