About W22

W22 is the ICD-10-CM diagnosis code for striking against or struck by other objects. It belongs to block W20-W49 (exposure to inanimate mechanical forces) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: W22.0 (object), W22.1 (airbag) and W22.8 (objects).

Don't report W22 together with the conditions in its Excludes1 note: striking against or struck by object with subsequent fall (W18.09).

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