I had the Serology 7 test done and my insurance did not cover it. I had my GI's office submit two letters to my insurance, and it was still denied. In the meantime, Prometheus was coming after me for payment...I contacted my insurance directly and they said to submit an appeal and I did so, only to find out they have a 6 month window on appeals and I missed it by a week. As it stands, I was left with the entire bill.
I was irritated I had the test done for a couple of reasons. First, my first GI had the blood test run right after I had my scopes, so I was groggy and had no idea what they were testing me for. Second, and I am sure the GI knows this from past experience, I wish they would have asked me BEFORE doing the test, so I could check with my insurance company. I realize doctors want to do what's best but with something that it seems most insurances see as "experimental" they should, at least, give you a choice and the chance to see if it is covered first.
If I had to do it again, I would have been a lot more pushy with both the doctor's office and my insurance. I wish you the very best of luck with getting this covered!
