There's a medical code for just about every medical condition or cause, it seems, from being struck by shoe cleats to being bitten by a dolphin to walking into a lamppost for the first time. For fun, search this directory at the WSJ.
The US edition of International Classification of Diseases, 10th Revision, will be expanded to include around 140,000 codes. Enjoy!
