No - the UK NHS is based on the idea of "free at the point of delivery".
Just to be quite clear here, since our American friend seems a bit confused:
1. Everyone who works pays national insurance contributions in addition to income tax; this runs between 7 and 10% of salary, but there is a lower limit below which no payments are required.
2. In return we get free healthcare, disability benefit, unemployment benefit, income support, maternity and paternity pay, statutory sick pay, the state pension, and the other aspects of the welfare state. In Scotland residential care of the elderly is also free, as are eyesight tests and some other additional areas.
3. For the avoidance of doubt, all medical treatment is entirely free (with the exception of some out patient prescriptions).
4. There are no excesses. There is no risk that people without insurance will not receive full treatment. There are no insurers arguing about whether treatment is or is not necessary, or whether it is covered under the policy. There are no exclusions for pre-existing conditions.
5. In all fairness, there are waiting lists for some - principally elective and non essential - treatments but normal medical treatment is pretty much immediate.
I speak from experience, having knackered my knee on 9th December, had an arthroscopy on the 16th, then been readmitted with a potential clot (it was
only double pneumonia). I've now been offered a further arthroscopic synovectomy as soon as I recover from the pneumonia, probably in mid March.
6. The French have an even better, broadly similar system although they pay a bit more by way of national insurance premiums (and consequently have a commensurately better system).
The major philosophical difference, I suppose, between Western Europe and the States (and I have spent time in the US) is that all-inclusive, comprehesive healthcare (something Medicare doesn't really provide) is considered a human right and hence the emphasis on "free" medical treatment.
But don't start me on money grabbing dentists, most of whom refuse to participate in the NHS programme (a big problem in England, less so in Scotland and Northern Ireland)
