I had all sorts of trouble getting my insurance to pay for Humira (Humana). They flat out denied me. I appealed twice, I believe, and after that I was accepted into the Abbot Patient Assistance program. It's a lot of pushing papers and a big pain to do. You have to get your doctor involved to fax over necessary paperwork and such and it could take several weeks to get it going but now I get my Humira delivered to my workplace for FREE in a big ice chest. They send me 6 pens at a time and when I need to refill all I have to do is call. I started the program in June and I know it lasts a year and then you have to re-apply but as far as I know as long as you have documentation that you've filed with your insurance, have record of every appeals and denials, then you should be able to be accepted to the program. Once you get in the Abbott people that I deal with on the phone (i.e. ordering) are very, very nice and they give you an exact date when you're medicine will be delivered so you know when it is coming.

Like I said, the process was tedious, but in the end it was worth it. I have my medicine.... and it's free.
