is there a way to see the customer billing is to know what the co-pay charges are electronically?

I can't give a certain answer but if you are not already enrolled in eBenefits and MyHealtheVet do so. I'm enrolled in both. I've never tried to access billing information. Otherwise call billing and ask if you can do that electronically. Hope this helped.

That is exactly what you should do!

You can call accounts receivable and they can answer that.

That was exactly what I was going to suggest
