About B83

B83 is the ICD-10-CM diagnosis code for other helminthiases. 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: B83.0 (migrans), B83.1 (Gnathostomiasis), B83.2 (cantonensis), B83.3 (Syngamiasis), B83.4 (hirudiniasis), B83.8 (helminthiases) and B83.9 (unspecified).

Don't report B83 together with the conditions in its Excludes1 note: capillariasis NOS (B81.1).

The conditions in its Excludes2 note aren't part of B83, but may be coded alongside it if the patient has both: intestinal capillariasis (B81.1).

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