You do not need to transfer anything from your current biller. Just contact Office Ally and they will tell you what to do. I found them to be very helpful. They also have manuals and web training. I am using their billing module and practice management module called practice mate. Mr. Scalpel is right: the most important thing is chasing denials and it is much less cost effective for us as family doctors than for surgeons.
On the other note it is quite frustrating that we have to deal with all those issues outside AC. It does not have to be this way. Unfortunately, I see some users actually urging the owner not to attract the capital (not to get "sold to big companies", etc) Here we have a great EMR - Amazing Charts, produced amazingly well by family doctor. And I say great product not necessarily because of the price, I had a chance to evaluate closely eCW, soapnotes and a few others. I liked AC best. But AC needs a further development, rapidly and simultaneously on many fronts. That can not be accomplished without investment and big muscles behind the whole project. There are certain rules in play when it comes to business and it does not matter in principal if it is EMR company or publishing company or computer or car production. I do not think there will be any more advantageous environment to sell EMRs than now. Stimulus money (even if it is a complete BS it still generates a lot of interest), the fact that the health industry is one of very few which is not "under" yet, general feeling among doctors that EMRs are inevitable - all these factors contribute to urgency to come up with COMPLETE product for small or medium size medical office. Why did eCW sign up with Sam's club? Why AC is not sold at Costco? Because management at eCW works accordingly to old russian saying - it does not matter if we are trying to sell a "rotten" product as long as our buyer is blind. So they put a lot of resources "to blind" the buyer so to speak. AC is superior product by itself but needs resources for development. The Owner does not have to surrender his vision and direction. It can be accomplished in a way Steve Jobs directs his company. ( I am not a fan of Apple but I do respect their business culture).
