Hey Dani.
If it makes you feel any better, the thingy doesn't actually stick out of your head. It's pretty much flush with the skin around it. It's not like you're going to have to walk through doorways sideways or anything.
My doctor said I might have a small spot around it where the hair didn't grow back, but I don't. I actually have a hard time somedays moving the hair out of the way to attach the processor.
That being said, I think, but don't quote me on this, that they bill for the whole thing at once - surgery and the actual processor. I know my doctors office submitted it all at one time, so it was already paid for, just waiting to be attached to my "sticky outy thing". If they are able to to that, you wouldn't have to worry about the insurance being terminated before you could get the processor. You would have to ask the billing person at the doctors office how they work it, and explain your situation to them.
Is the insurance your only real concern, or are you concerned about the surgery too? I know mine wasn't bad at all.
