I don't think it is AC, Newcrop, Clearinghouse. It is likely CVS, and there may even be a good reason.
Automatic refills to eRX is just that. In order for you to get a fax,CVS has to fax you. Plain and simple. I don't think NewCrop has anything to do with faxes.
Again, there are reasons it is done. I will talk to my people again. I can certainly talk to NewCrop.
