I had full coverage for surgery and fills with the BCBS Federal Employee plan. I'm not sure what the PPO offers, but check the booklet that you should be able to get from your employer or BCBS. Mine specifically said that it covered restrictive and combination procedures.
I had the lap band done in July and my total out of pocket has been less than $2000. If you want to, you can sent me a PM or email me at
