About B17

B17 is the ICD-10-CM diagnosis code for other acute viral hepatitis. It belongs to block B15-B19 (viral hepatitis) 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: B17.0 (carrier), B17.1 (C), B17.2 (E), B17.8 (hepatitis) and B17.9 (unspecified).

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