Hey guys
I use TotalMD and Gateway EDI as a clearinghouse and after a 2-3 month learning curve we are finally filing clean! I started late December, and our last batch had only 3 rejections! Best of all, Gateway is so good at keeping track of what is not paid, it is just a matter of resubmitting the failed efiles, so you don't lose any in the shuffle. The transition from AC to TotalMD requires you to "polish" each submission (ie add a clia number or referring provider number) but is otherwise clean.
Take care
