Labcorp installs an interface and then it is turned on by AC - you still have to pay the fee, but Labcorp historically pays the fee for you. You just need to speak with your rep. Jon from AC coordinates the interface and I do not believe that Labcorp gets any data from AC - it just allows you to import the data. I think the advantage of getting actual HL7 data will become more apparent as CCHIT requires the integration of data.
I personally use PAML with a lab interface, but I think you really should bite the bullet and get the lab interface (one time fee they pay as long as you pay for guardian angel tech support yearly).
