K.D.
I've called and successfully negotiated a hospital bill, but more recently it seems they are more hard nose on negotiating, even saying they can't negotiate on balances determined by insurance to "be your responsibility." I have even had billing departments require payment in full of large balances with 3 months and no longer with the slightest default sending you into collection agencies and bad credit marks. So, I think it is going to depend on the hospital itself and your financial ability to pay. I would definitely give it a shot. If they don't and you don't qualify financially for hospital assistance (based on income) then I would guess the only 2 options you have are to pay it or let it default, go to collections unpaid for a period of time until they are either ready to make an offer.
I am curious to see how it turns out for you. Keep us posted.
