Miliary tuberculosis, unspecified

This code represents a disseminated form of tuberculosis characterized by widespread, small (millet-seed sized) lesions throughout multiple organs, typically the lungs, but potentially affecting the liver, spleen, and bone marrow. It signifies a severe, systemic infection with Mycobacterium tuberculosis that has not been further specified regarding its site or manifestation.

This code is appropriate when documentation confirms a diagnosis of miliary tuberculosis, but the specific organ system or site of involvement is not detailed. It should be used when the physician explicitly states "miliary tuberculosis, unspecified" or similar terminology without further anatomical specificity.

• Do not use this code if the specific site of miliary tuberculosis (e.g., miliary tuberculosis of lung, miliary tuberculosis of meninges) is documented; instead, use the more specific code.
• Always review the entire medical record for any mention of specific organ involvement before assigning this unspecified code.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter, followed by codes for any associated complications or manifestations.
