I panicked when I read this thread, as I have lapband surgery scheduled for early May.
But I got my DH to ring Medibank Private, and they didn't know anything about it (item number 30511) being declined. In fact they wanted to know where we heard that.
They're even sending me a letter confirming acceptance.
I am in SmartPlus (Hospital plus Extras) so I don't know if that made a difference or not.
I'm just soooooo glad I'm still covered (fingers crossed nothing happens to change that by the date of surgery).
PS I'm being banded by Dr Munro at North Gosford Private Hospital (NSW), and have started Optifast although I haven't even seen the Dr yet - my appt is next month.
