So, an orca (9 codes) and a squirrel (6 codes) have their own damn codes but a friggin bear is in the other category?!? Heck, wolves, coyotes, bears, and mountain lions all don't have their own codes. I see a lobbying effort that needs to go on to show the true nature of dangerous animals in the US and quit hiding these attacks in the other category.
On the other hand, I do like the difference between cats and dogs:
W540XXA Bitten by dog, initial encounter
W540XXD Bitten by dog, subsequent encounter
W540XXS Bitten by dog, sequela
W541XXA Struck by dog, initial encounter
W541XXD Struck by dog, subsequent encounter
W541XXS Struck by dog, sequela
W548XXA Other contact with dog, initial encounter
W548XXD Other contact with dog, subsequent encounter
W548XXS Other contact with dog, sequela
W5501XA Bitten by cat, initial encounter
W5501XD Bitten by cat, subsequent encounter
W5501XS Bitten by cat, sequela
W5503XA Scratched by cat, initial encounter
W5503XD Scratched by cat, subsequent encounter
