About W21.210

W21.210 is the ICD-10-CM diagnosis code for struck by ice hockey stick. It belongs to category W21 (striking against or struck by sports equipment), 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.

Within W21.21 (struck by hockey stick), W21.210 is specifically for struck by ice hockey stick. Related codes cover field hockey stick (W21.211).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
