I got mine to work with $400 upgrade (paid by McKesson as I am persistent) - spoke with the company who did it and they are in my State - for about 1,000 per year will provide ongoing support and switch me to new clearing house (Availity) instead of one through McKesson... still use Medisoft but change clearinghouse. I already pay 100-150 per month for RelayHealth and that will go away - Availity is free.
I may eventually switch to AC PM once it is perfected as I really hate medisoft and the ability for anyone to look up amount due, etc would be great.
