I just happened to have the Jan 2007 Coding Edge at my desk. How's that for coincidence? Page 29 lists the State Coders Day. Arizona is July 14. I was looking for ours also (Indiana) and was told it was in November but was unsure of the day. It's November 9. Pretty cool huh? LOLFunny you should ask this now. I was looking at an old copy of the Coding Edge from Jan 2007 I believe last night. It had a map with State Coder's Day listings. I think 33 states have Coder's Day and it listed the dates. If I remember I will look today at Arizona and let you know. You could also check with the local chapters there, it is usually a chapter that gets the ball rolling. I am in DC and we actually petition the Mayor's office and he gives us a proclamation. District Medical Coder's Day is July 12th.
