My staff is celebrating the end of tracking down paper superbills!! My billing company is MTBC.com. We just contacted them and they gave the staff instructions in transferring the data directly to them. They already have experience w/ AmazingCharts and only charge 4%. They did tell me they are working w/ AC on some glitches in the transfer of data that does need to be sent separately in a message. I think it has to do w/ modifiers but we just started doing this a few days ago so I am still learning.
