Acute miliary tuberculosis of multiple sites

This code signifies a severe, widespread form of tuberculosis characterized by the hematogenous dissemination of Mycobacterium tuberculosis throughout the body, leading to the formation of numerous small, millet seed-sized lesions in multiple organs. It represents an acute, systemic infection affecting various anatomical sites simultaneously.

Apply this code when documentation explicitly states acute miliary tuberculosis with involvement of more than one organ system. This typically occurs in immunocompromised individuals or as a complication of primary TB. Documentation should clearly indicate the acute nature and multi-organ involvement.

• Ensure documentation specifies "acute" and "multiple sites" or lists several affected organs.
• Do not confuse with chronic miliary tuberculosis or miliary TB affecting a single site.
• Sequence as the primary diagnosis when it is the reason for the encounter, followed by codes for specific organ manifestations if further detail is needed.
