Boy I don't know about the units since I've not had to bill that many units. However, I do know that I cannot add certain modifiers, specfically the QW which we have to use a lot.
I'm not sure why the restrictions. Since we currently are billing though office ally (though we are going to be outsourcing again), we have to change the HCFA on that end to do what we want.
Others have suggestions?
