Other mycobacterial infections

This code signifies mycobacterial infections that are not tuberculosis and are not otherwise specified as leprosy or specific atypical mycobacterial diseases. It encompasses a range of infections caused by various non-tuberculous mycobacteria (NTM) that do not fit into more specific ICD-10-CM categories.

Apply this code when documentation confirms a mycobacterial infection, but the specific species or type of NTM is not identified, or the infection is not explicitly classified elsewhere. This is appropriate for NTM infections of the skin, soft tissue, lymph nodes, or disseminated disease when a more precise NTM code is unavailable. Documentation should clearly state a mycobacterial infection, excluding tuberculosis and leprosy.

• Do not use this code if a more specific NTM infection code (e.g., due to Mycobacterium avium complex) is available and documented.
• Always sequence this code after the definitive diagnosis of the mycobacterial infection, if applicable.
• Ensure documentation explicitly rules out tuberculosis and leprosy before assigning this code.
