About W59.22
W59.22 is the ICD-10-CM diagnosis code for struck by turtle. It belongs to category W59 (contact with other nonvenomous reptiles), block W50-W64 (exposure to animate 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 W59.2 (contact with turtles), W59.22 is specifically for struck by turtle. Related codes cover Bitten by turtle (W59.21) and other contact with turtle (W59.29).
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.
