Differences in hospitals

So the bills are processed and it looks like it cost $460 more to have the cast applied in B.oston vs C.incinnati. The savings is that I didn't need a plane ticket, rental car and hotel room but I still wasn't expecting such a difference in the cost. Both were put on with the deductible for the year being nice and fresh so it is a fair comparison (Daddy started his new job 3 weeks before the first cast was applied). I was a bit worried when I saw that B had submitted more than twice the amount C did in claims. The total bill for us comes to $1320. Yeouch! Looks like we will be hitting our out of pocket max for the year early this time. Sigh.
