I work at a Doctor's office and the provider line is absolutely awful. It constantly gives you the run around and under no circumstances does it let you reach a representative. I had to call the member services number and argue with a rep there to transfer me to the provider rep. When I transferred, the rep told me I had to go to evicore for the PA. When I tried to use the evicore website, BCBS of IL wasn't even a listed insurer. So I had to call that member number again. They told me if I call the provider number and say I don't know the DOB on the patient, it will connect me to a provider rep. Finally, I got a phone a number for evicore and was able to do the PA that was pended and will probably end up denied. Regardless, this has been by far the worst experience I've ever had with an insurance company.
