Hi Khill,
You asked, or I wouldn't put this link here. This is going to sound like an ad, please forgive me - unless someone asked, I wouldn't even put this up here. Michelle Hannon gave you some excellent links, but if you want more information, there's a way you can get it.
DecisionHealth puts on an annual 2-day anesthesia conference - on all things anesthesia! To be fair, I'm a speaker with them and one of my topics is going to be on
medical direction, what it means, how it works, the whole bit - and I'll include a handy-dandy cheat sheet along with direct, black & white links from CMS & other places where you can find solid information to show your docs.
Ask your docs to send you so you can have the answers they need -even bring one along. Kelly Dennis will be there, as well as Dr. Pam Upadya and a bunch of others. If you want to spend some time with the pain management team, they're awesome too - Marvel Hammer, Judi Blaszczyk & some others, sometimes they let you go to both tracks so you can get the most out of the time you're there.
Anyhow, you can find information that you need by going here:
