Update:
I did get in touch with a co-ordinator today. She (co-ordinates) between the GI, the infusion center, the drug company, and handles the paperwork for insurance, and any additonal financial assistance.
The good news is, that whatever portion my insurance won't cover, there's an extended plan to pay for the balance.
So right now it looks like there will only be a minimal cost to me each month.
Rough numbers being, I would have had to pay about $400-$500 a month without this, so it's really significant.
Thanks to everyone for replying.
Tom.
