Insurance Approved my surgery... I think there is a mistake

I have BCBS and they approved my revision without the 6 month wait due to my gerd. Maybe they processed yours quickly for similar reasons? Definitely make sure you get it in writing, if the paperwork is in order I would proceed with your revision. Perhaps your Dr included a letter suggesting they proceed with surgery sooner rather than later as well. The dr insurance coordinator should be able to elaborate as well.
