About W21.2

W21.2 is the ICD-10-CM diagnosis code for struck by hockey stick or puck. 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 2 subcodes must be used instead.

Within W21 (striking against or struck by sports equipment), W21.2 is specifically for struck by hockey stick or puck. Related codes cover struck by hit or thrown ball (W21.0), struck by bat, racquet or club (W21.1), struck by sports foot wear (W21.3), striking against diving board (W21.4), striking against or struck by other sports equipment (W21.8) and striking against or struck by unspecified sports equipment (W21.9).

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.

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