Just have the nurse put it in your chart: "Patient is allergic to foolishness".
I've had a couple of surgeries, one of which was more specialized (in the sense, a very limited number of surgeons perform it, though the number is increasing). For one, I had my parents' insurance still, so that was all dealt with, and really I could've had it at just about any hospital with a competent GI surgeon. The second one I had medicaid, which paid for everything (thank god), it was just a question of the scheduling wheels turning slowly (meet the surgeon, pre-op appointments, actual surgery, etc, but I was got in early d/t a cancellation). Now, I have a partially subsidized plan, but it's the first time I've had a plan where my local (5 mins away) hospital is out of network for anything but emergency visits. The specialty hospital is among the best in the country, so I'm perfectly happy to have it there, it's just that, OR time is a limited resource, especially for a hospital doing such a high volume of orthopedic procedures daily. It was frustrating to get a date, frantically arrange things, then be told "um, actually..." And have to frantically re-arrange things and tell people "...ok soon, but I don't know when, I'll get back to you". It might be a week of delay, or two weeks, or a month. I do get the sense this surgeon will go to bat for me, because when we looked at my MRIs, he got very distressed when my reply to, "How are you walking around not in excruciating pain?" was "Well, I am in pain, but I have a life and no real choice, so I just have to accept it."
The funny thing is, I saw this exact scenario with a patient a few years ago. He needed some toes amputated, which pretty much any fool with an MD and a set of bolt cutters can do, so he went to Local Hospital, but because of his insurance had to be transferred to a large downtown trauma center, admitted and have the surgery there - and his wife didn't drive. Absolute nonsense.
