98% of my 2017 IL U65 biz is with BCBS - about 400 people / families
There are issues / problems pretty often but really not very bad this year - and I'm yet to have them NOT deal with a problem the right way - tho you may have to call them several times. There's usually some info missing that's holding up a resolution - that they didn't communicate to client or me. Like SEP documentation etc.
They never reach out, you have to call & ask - and ask for supervisor if the 1st rep is unable to help. Seems like there are a lot of new phone reps in Cust Serv.
Also, my mgr will step in if I need another level, is responsive. Having a decent size book seems to help.
The biggest problem I have is people new to HMO
not wanting to accept how it works - and that they can't see their out-of-network old Dr's and have it be covered. That's not a BCBS issue. Its an emotional one
