B88.0Other acariasis

B88.0 is the ICD-10-CM diagnosis code for other acariasis. It belongs to category B88 (other infestations), 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 2 subcodes must be used instead.

Within B88, choose B88.0 (Other acariasis) only when documentation doesn't support a more specific option: Tungiasis [sandflea infestation] (B88.1), other arthropod infestations (B88.2), external hirudiniasis (B88.3), other specified infestations (B88.8) and infestation, unspecified (B88.9).

To report this condition, pick the subcode that matches the documentation: B88.01 (mites) and B88.09 (acariasis).

The conditions in its Excludes2 note aren't part of B88.0, but may be coded alongside it if the patient has both: scabies (B86).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2026 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 133.8 (other acariasis).
