FED insurance and job change??

I may have a good chance for a job change with a different agency and it be well worth my time to take it, so far they have gotten a reference from my supervisor so it looks good. I have e-mailed HR (VT) and trying very hard to find out if "CIS" carries the Fepblue with the 3 mo WLS lapband plan - no answer ---If you know anyone who works for them, If they have the BCBS fed plan and if the coverage is the same with the same WLS prerequisites, please let me know...
I know it is alot to ask, but the job is falling right in the middle of when the surgery could take place.
- I am stressed because I do not have a surgery date until after OCT 6 when paper works is submitted, and I really would like to know what to say, with out giving all my surgery details, should they send me a job offer. I know I am rambling, It's like too many blessing at once!
