About the W50–W64 Code Range
These events involve contact with another person, an animal, or sharp parts of a plant. The categories first separate the source of contact. Some then distinguish the action or the specific animal.
W50 separates accidental hits, kicks, twists, bites, and scratches by another person. W51 describes bumping into another person, while W52 describes being crushed, pushed, or stepped on by a crowd.
Animal categories distinguish rodents (W53), dogs (W54), other mammals (W55), and nonvenomous marine animals (W56). They also distinguish nonvenomous insects and other arthropods (W57), crocodiles and alligators (W58), other nonvenomous reptiles (W59), birds (W61), and nonvenomous amphibians (W62). W60 describes contact with plant thorns, spines, or sharp leaves. W64 describes other animate mechanical forces.
Each category lists a seventh character for an initial encounter, subsequent encounter, or sequela, meaning a later effect.
