We went live on 3/1/15. The training prior to that was fine but very basic. You really can't learn alot of the things until you are actually working in the system. AC took too many practices live on the same day without enough support staff, so I have found it hard to get answers to my questions in a timely fashion. Also, I was not aware that I would have to re-enter all the appointments into the PM side and re-enter all the insurance information for each patient. They did offer to help with the appointments, but we are a fairly small practice so it wasn't a huge deal - just a surprise I wasn't prepared for! Another issue I have encountered is that the insurance company addresses are not entered for any of the insurance companies, causing claim errors. Other functions and tables have not been set up correctly (my eligibility check is not working yet, etc.). I'm sure once we get all the kinks worked out it will be great. I have been able to submit electronic claims once I added the insurance company addresses. Just be prepared for it to not go smoothly right at first!
