The mom in law(yank) had kidney stones removed whilst on a visit here. 4 days in a ward plus scans x-rays etc =£500+ bill. It is procedure to treat foreign nationals as private patients and therefore bill them appropriately. I think someone overlooked the treatment you mentioned.
ps
Private med ins covered her travel meds too. They pay for it but it covers a damn site more than our rip off merchants!(read the small print....sorry you're not covered) bugger.
