BCBS HMO IL-Chicago

Hello everyone, I have BCBS IL HMO. Just recently changed my medical group for logistical purposes. I went to the doctor and we discussed WLS. She stated that she would be unable to put in the referral because I had not been a member of the medical group for one year. I know my health insurance covers this surgery, but she said she cannot make a referral for one year. Has anyone ever heard of this. Is this true for all medical groups? I can change, but would like to find a group that does not have such strict policy. I am currently with Presence Medical Group.

I have BC/BS of PA and I didn't need a doctor referral.
