It can be pretty stressful when the medical bills start adding up. For last year's expenses, I've taken the approach that it is what it is. I was not able to plan for the large medical expenses of last year so I'm SOL. However, for this year, I've set aside enough money in my pre-tax FSA to cover my out of pocket max which I know I'll hit with my remicade infusions.
Also, You might want to check if the hospital will allow a payment plan. I had some serious hospital bills from this summer that they allowed me to pay for over a year. Not sure if all hospitals do this but it's worth a try.
