Sorry for the delay in responding!
First, I do not know anywhere you can get a crash course in Medisoft. If you have any other Practice Management Software experience and you are pretty proficient on the computer you should be fine. It is a fairly user friendly software. You could always go to the Medisoft website and see if they have a demo.
As far as top 10 claim denials, that's a great idea for an article. I will email you when it is done. Too long to include in this post. Alice did write an article on appealing a denial. You can read it at

I also am not aware of any HIPAA courses, but we do have an articles= about HIPAA that may help you,
http://ezinearticles.com/?HIPAA-And-How-It-Will-Affect-Your-Office&id=195696Pre-auth can usually be obtained by calling the insurance company. In some cases, the company has a form that they require that you fax in for pre-auth. Each company has their own requirements. Anyway if you just understand what pre-auth is, and the importance of getting it, you should be ok. If you don't know with a particular company, just call the insurance company and ask what they require.
Good luck!
