Does anyone know how long it takes BCBSTX-FEP to determine approval/not approved once paperwork is submitted and is there a way to check the status online?

I have BC BS FEP in TN...I was really disappointed with the process. The doctor submitted my paperwork and I kept calling the 800 number to see if it was received. Each time the person would say they don't know if it was received or not (no system to tell), that it would be posted when it was approved. After 4 weeks of calling another guy on the phone said if we had received it, it would show in the system as pending approval (totally opposite of what I was told for 4 weeks). At this point my doctor resent the package and I called a week later and it was received and approved. I just called the BCBS 800 number, they'll tell you when it's approved...but my doctor didn't get the letter til a week later (they wouldn't schedule me without it). So...with that being said I would make sure they show it in the system and don't give you the run-around like I got. No way to check it on-line, they only show paid or pending claims. Once it's received it's fast!
