I going to sound like a whiner. I have BCBS and the process really did move forward quickly. The snag I had was my PCP. He outsourced my chart being copied and it took almost 6 weeks of chsing them. The first few weeks the company didn't come in to make the copies. Then when they made the copies they sent them to Altanta, I live in Michigan, and mailed me a bill to pay them $29.18 for the copies before they would send them to the suergeon. Once I paid online the very da I rec'd the invoice they snail mailed it to the suergeon.
So, with the whole process of 6 and half weeks I shouldn't complain. It really depends on your insurance company.
