It's likely that you'd have issues in pretty much any country in the world with your conditions. For example many european single-payer systems have tons of exceptions. Covering only basic tests/procedures/drugs (premium available out-of-pocket only), queues (jumping queue is possible by paying out-of-pocket) and incompetent doctors (longer queues at the good ones). And you pay a huge insurance for this, so there's not that much money left to pay out-of-pocket for most people.
