In my opinion, you're needlessly worrying about something that MIGHT happen. Do you have any inkling that your insurance is about to change? If not, don't worry so much. If you're ready to get the band, do it now when you know for sure that it's covered. If your insurance changes, then you worry. If it doesn't, that's a long time and a lot of energy you've spent on something that isn't happening.
Good luck!
