Other meningococcal infections

This code represents meningococcal infections that do not fit into more specific categories of meningococcal disease, such as meningitis or septicemia. It encompasses less common or atypical presentations of Neisseria meningitidis infection affecting various body sites.

Use this code when documentation specifies a meningococcal infection that is not meningitis (A39.0), Waterhouse-Friderichsen syndrome (A39.1), acute meningococcemia (A39.2), or chronic meningococcemia (A39.3). Examples include meningococcal conjunctivitis, arthritis, or pneumonia, when the organism is identified as Neisseria meningitidis. Documentation should clearly state the site of infection and confirm it is meningococcal in origin.

• Do not use this code if a more specific meningococcal infection code (A39.0-A39.5) is applicable.
• Always sequence this code after the specific manifestation of the infection, if applicable (e.g., H10.89 for other conjunctivitis, then this code).
• Ensure the documentation explicitly identifies Neisseria meningitidis as the causative agent for the "other" infection.
