About Y08

Y08 is the ICD-10-CM diagnosis code for assault by other specified means. It belongs to block X92-Y09 (assault) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Y08.0 (equipment) and Y08.8 (means).

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