Other specified mycobacterial diseases

This code identifies mycobacterial infections that are not tuberculosis, leprosy, or other specifically classified mycobacterial diseases. It encompasses a range of atypical mycobacterial infections affecting various organ systems, often seen in immunocompromised individuals or those with pre-existing lung disease.

Apply this code for documented diagnoses of non-tuberculous mycobacterial (NTM) infections where the specific species is identified but does not have its own distinct ICD-9-CM code, or when the physician specifies "other" mycobacterial disease. Supporting documentation includes culture results, pathology reports, and physician notes detailing the specific NTM organism or the "other specified" nature of the infection.

• Ensure the documentation explicitly states "other specified" or identifies an NTM species not otherwise classified.
• Do not use this code for tuberculosis (010-018) or leprosy (030).
• Consider an additional code for manifestations or complications of the mycobacterial disease, such as lung disease or lymphadenitis.
