I would have your doctor's office find out. Before I had my first treatment, my doctor's office found out what the copay or percentage would be and found the least expensive place for me to have the infusions.
When I looked up Remicade online for my insurance, it also said it was not covered but then in the "nitty gritty" details, I found out that certain conditions needed to be met before it was covered. I don't know if BCBS is set up the same way online as my insurance is, but when I looked under RX for Remicade, it said not covered, but I did a search on their website and found a document stating it would be covered, and for the reasons.
Keep us updated on what you find out and best of luck!
