Cutaneous diseases due to other mycobacteria

This code describes skin infections caused by mycobacterial species other than Mycobacterium tuberculosis or Mycobacterium leprae. These atypical mycobacterial infections often manifest as chronic skin lesions, nodules, or ulcers, which can be localized or disseminated.

Assign this code when documentation specifies a cutaneous infection confirmed to be caused by a non-tuberculous, non-leprous mycobacterium. This typically follows laboratory identification of the specific mycobacterial species from a skin biopsy or culture. Common scenarios include infections from M. marinum (fish tank granuloma) or M. fortuitum.

• Ensure the documentation clearly distinguishes the mycobacterial species from M. tuberculosis (017.0x) or M. leprae (030.x).
• Code any associated open wound or ulcer separately if applicable, following sequencing guidelines.
• Do not use this code for systemic mycobacterial infections without specific cutaneous manifestations.
