About B65

B65 is the ICD-10-CM diagnosis code for schistosomiasis [bilharziasis]. It belongs to block B65-B83 (helminthiases) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: B65.0 (schistosomiasis]), B65.1 (schistosomiasis]), B65.2 (japonicum), B65.3 (dermatitis), B65.8 (schistosomiasis) and B65.9 (unspecified).

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