Cervie, I heard the same "non-payment" policy of Medicare. But I also heard that they will pay for hospital charges, right? That would leave the cost of the device and procedure; both of which may be negotiated (attempted, I should say).
That leaves you with more options -- and more work. But don't give up, keep asking questions, make phone calls, take notes...keep us posted too. Your progress (I believe in you!) will help other people as well!
