If you can be one of those... Mom (age 66) just had rotator cuff surgery. Turns out since she did not stay overnight in the hospital, Medicare will not pay for it and she was under the impression that they would. Her insurance picked up 38 thousand of the surgery, but now she is on the hook for 22 thousand. Is there an appeals process? What is her chance of getting the appeal? What is her option if the appeal is not approved? Thanks for the help.
