Additional Info

• Mycobacterium Tuberculosis is the pathogen that causes tuberculosis (Tuberculosis of the respiratory system, confirmed).
• The M. tuberculosis complex (MTBC) includes four other TB-causing mycobacteria:
  • M. bovis
  • M. africanum
  • M. canetti
  • M. microti

• Includes:
  • tuberculous involvement of the GI tract
  • renal tuberculosis
  • combine with Lymphangitis for a lymph node tuberculosis infection (also called TB lymphadenitis)
  • Use this code combined with Infectious disease NOS for treatment of latent tuberculosis
  • For TB of any organ not listed under "excluded: below, use this code (Mycobacterium tuberculosis (M. TB)) with an "NOS" code for the organ in question.

• Excludes:
  • Observation for SUSPECTED tuberculosis
  • Infectious contact/exposure, tuberculosis, without disease (yet)
  • Past history, tuberculosis, believed cured or inactive
  • We have specific codes for the following organs affected by TB:

• Arthritis, due to tuberculosis
• Bone, tuberculosis (tuberculous osteomyelitis)
• Spine, tuberculosis (Pott's disease)
• Tuberculosis of the nervous system
• Tuberculosis of the respiratory system, confirmed

Double Duty Pathogen code

• SMW

• Cargo

• Categories

This ICD10 code does double duty as both a pathogen and a disease condition:

• as the Infection with implied pathogen tuberculosis of other organs for which we don't have a specific code
• as the pathogen any pathogen from the Mycobacterium tuberculosis complex
