Aaron,
To answer your actual question, yes she most likely will receive a statement in the mail showing that it was paid(it normally gives the detail of how much was paid by health insurance, how much the doctor or health care facility had to write off, and then how much is the participants portion to cover). So, if it's your moms health plan and you are on it, I donkt see a way around that. With that being said, if your doctor says that a hysto is medically necessary then it most likely is to ensure your continued good health and safety; hopefully your mom will be able to see that. Also, I agree with the previous posters...this is your life, you need to make yourself happy. Besides once you've had the surgery even if she receives the statement from insurance it will be too late anyway and at least you will have had the surgery. I say go for it. Good luck!
