ICD-10-CM A19: Miliary Tuberculosis Overview
This group represents disseminated tuberculosis infections characterized by numerous tiny lesions throughout multiple organs, typically due to hematogenous spread of Mycobacterium tuberculosis. It targets systemic infection rather than a single organ system and may involve lungs, liver, bone marrow, and central nervous system. Accurate coding is important for reflecting disease severity and complexity, which affects clinical documentation and reimbursement.
