Wow--I'd never heard of this and I hope it doesn't become more widespread.
CIC--Janssen specifically says that they will cover deductible payments, so I think your reprocessing probably comes from your insurance company. This is from the Carepath website:
-------------
If you are eligible, you may be able to lower your out-of-pocket costs for REMICADEĀ®, including deductible, co-pay, and coinsurance medication costs. With Janssen CarePath Savings Program for REMICADEĀ®, eligible patients pay just $5 for each infusion for your REMICADEĀ® medication costs, with a $20,000 maximum program benefit each calendar year.

Thus far, our insurance company doesn't care about our payments from Janssen. We get our bill from insurance (we have a 20% copay on Remicade costs), pay our insurer, and then submit the bill to Janssen and get the money back; no reprocessing required. Most years we get back most of E's out-of-pocket expenses, since Remicade is by far our biggest expense.
