Disseminated due to other mycobacteria

This code describes a systemic infection caused by mycobacterial species other than Mycobacterium tuberculosis (which causes tuberculosis) or Mycobacterium leprae (which causes leprosy). It indicates that the infection has spread beyond a localized site to affect multiple organs or systems throughout the body. These "other mycobacteria" are often referred to as nontuberculous mycobacteria (NTM) or atypical mycobacteria.

Use this code when documentation specifies a disseminated infection due to a mycobacterium that is explicitly identified as non-tuberculous and non-leprous. This typically occurs in immunocompromised individuals, such as those with HIV/AIDS, or patients on immunosuppressive therapy. Supporting documentation should clearly state the disseminated nature of the infection and identify the causative mycobacterial species (e.g., M. avium complex, M. kansasii).

• Do not use this code for tuberculosis or leprosy; specific codes exist for those conditions.
• Ensure the documentation specifies "disseminated" or "generalized" involvement; localized NTM infections are coded differently.
• Always sequence this code after the underlying condition (e.g., HIV) if applicable, as the NTM infection is often an opportunistic infection.
