They do in the sense that socialised medicine wont cover all treatments. In New Zealand some things are not "funded" but you can still get private cover to extend to cover state of the art treatments and be able to skip the queue. The difference is, that insurance costs a fraction of what it costs in the USA because the basics are all covered and the cost of providing state of the art care is drastically reduced since the hospital facilities/bed are still covered publicly.
