That's put a smile on my face to see her looking well but ouch, that's quite a bill. I had a transnasal craniotomy (surgery through the nose) back in 2012 to remove a pituitary tumour. Not technically brain surgery, but they did need to cut a hole in my skull to get to it. I spent a week or so in ICU to recover.

Luckily being UK based I didn't have a bill of any kind to pay afterwards and was paid in full while I recovered.
