In UK you are using NHS, a public service, funded out of your tax dollars. NHS spent over £124.7B in 2017/2018 so your average cost is about £2000/person. Not sure how you can break out costs for heart bypass but I suspect they will be much more than $2K/surgery. Narayana Hospital is private and has been profitable continuously, with $8M profit in 2017. And still their patient mortality rate is lower than the US (1.4% patients die within 30 days after heart bypass, compared to 1.9% in the US).
