About B87

B87 is the ICD-10-CM diagnosis code for myiasis. 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: B87.0 (myiasis), B87.1 (myiasis), B87.2 (myiasis), B87.3 (myiasis), B87.4 (myiasis), B87.8 (of other sites) and B87.9 (unspecified).

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