We go to billing and download the data to a simpletext file that is then sent by FTP to their servers. It will "scrub" the data a little bit and ask if DOB, guarantor or such demographic data is not filled in. If all the data elements are present, it only takes a couple minutes.
On their end they then go through the claims and electronically submit. Seems like they get them out within a week, probably sooner, I haven't really followed their submission pattern.
If you are submitting PDFs now, I would suspect it is pretty similar.
