About A39.8

A39.8 is the ICD-10-CM diagnosis code for other meningococcal infections. It belongs to category A39 (meningococcal infection), block A30-A49 (other bacterial diseases) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within A39, choose A39.8 (Other meningococcal infections) only when documentation doesn't support a more specific option: meningococcal meningitis (A39.0), Waterhouse-Friderichsen syndrome (A39.1), acute meningococcemia (A39.2), chronic meningococcemia (A39.3), meningococcemia, unspecified (A39.4), meningococcal heart disease (A39.5) and unspecified (A39.9).

To report this condition, pick the subcode that matches the documentation: A39.81 (encephalitis), A39.82 (neuritis), A39.83 (arthritis), A39.84 (arthritis) and A39.89 (infections).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
