The likelihood is that other nations, in fact every advanced nation in the world, pays less per capita than the US for health care is due to:
Providers know what they will be paid for a given procedure. There is no game playing by billing triple what is necessary and then hoping to collect enough to cover costs.
There is no need to go to the emergency room for non emergencies.
It is more likely that people will get preventative care when that care doesn't cost them.
There is no need to maintain an army of clerical staff whose expertise is to bill the correct entity and put the right codes in the correct boxes, then keep after the private for profit insurers to be sure that they meet their obligations.
There is no incentive to perform unneeded procedures and tests just to collect the money from insurance.
But, that's just a guess, and could be wrong. It could be a combination of all of the above, or there might be another reason altogether why we have the most expensive health care in the world, and no better outcome for the extra money.
