About B88

B88 is the ICD-10-CM diagnosis code for other infestations. It belongs to block B85-B89 (pediculosis, acariasis and other infestations) 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: B88.0 (acariasis), B88.1 (infestation]), B88.2 (infestations), B88.3 (hirudiniasis), B88.8 (infestations) and B88.9 (unspecified).

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