We've recently had an issue with a particular FSA card brand being declined at our pharmacies. Our credit card processor is telling us it is due to our POS passing them a NACS product code that is not eligible for an FSA payment. I'm not familiar with what that is. I see no mention of it in any ACE documentation nor can I find anything by searching with Google about how this data would be entered or configured in ACE.
I did a little experiment of my own. I got the product code that was "passed to them" for one of the declined transactions. I then found another transaction for the same item that was approved by them. They looked up the product code for that transaction and it was different. Same store, same item, different product code. Makes no sense to me.
Is anyone aware of an NACS Product Code? Is what our card processor telling us accurate?
