Unfortunately it's not all that strange. when i was working for the dental software company we were required to add a diagnosis code field to every treatment. Insurance, you know. We were laughing about one that said "horse fell on patient". I forget the code. Then one day a local dentist who is located near the race track called. Seems like one of the jockeys was thrown and the hose fell on his jaw. So those things that you think can't happen, do.
What happened to the jockey is not so sad. He recovered. What is sad is that my life is so boring that I have actually read the ICD-9 CM.
