That's quite absurd. Especially since it was a routine place you were going. You might try calling your insurance (if you havent) and talk them into reducing the bill: you just didn't know and your wife sticked with where she has been going to in the past. If you can, if your healthcare is through your employer, try writing to your benefits team as well.

PS: My prayers are goes for your wife. I hope she beats the cancer.
