Medical costs

I saw the full bill from the hospital (charged to my medical fund) for the right hip operation: just under $12,500. That includes the 4-night hospital stay, operating theatre fees, and the implant itself, but doesn't include the surgeon's and anaesthetists' fees (approx another $5,000, most of which is also covered by my medical fund). Presumably the other hip cost about the same except for one extra day in hospital. I suspect this is somewhat less than a comparable operation would cost in the USA.
