About A02

A02 is the ICD-10-CM diagnosis code for other salmonella infections. It belongs to block A00-A09 (intestinal infectious 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.

To report this condition, pick the subcode that matches the documentation: A02.0 (enteritis), A02.1 (sepsis), A02.2 (infections), A02.8 (infections) and A02.9 (unspecified).

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