Whatever it is they do exactly it deals with insurance companies. Germany also has private doctors but they have much smaller staff and dealings with insurance are very straightforward. American insurance companies cause a lot of friction. I don’t know exactly why but they do.
The biggest problem IMO is how we structure payment for health services in the USA. The fee for service model is highly inefficient and disincentivizes preventative care. All of the current proposals for universal healthcare do not address this fundamental problem, and so long as this remains in place we will continue to have the highest costs in the world. (disclosure, I am working to try and solve this problem)
If you were to pick countries to emulate, I would pick Singapore, Japan, the Netherlands, and Switzerland instead of Canada and the U.K.

> According to the Kaiser Family Foundation, administrative costs in Medicare are only about 2 percent of operating expenditures. Defenders of the insurance industry estimate administrative costs as 17 percent of revenue.

It's being pissed away when the hospital, and the insurer spend 2 hours arguing over how to bill a $500 procedure. Net cost? $640. $500 for the procedure, $35/hr * 4 hours for the paper-pushers.
Net benefit to the patient? Minus $100, out of their premiums. Would you like to pay cash, or discuss with us a financing plan?
It's being pissed away when the hospital buys bus ads, and the insurer buys superbowl ads. I've not seen a single hospital ad in Canada... Because the hospitals weren't competing for my business.
It's being pissed away when a hospital tries to sneak in a $100 bill for two aspirins, and justifies it by citing how much they spend on charitable care. (Hint: That charitable care is the hospital writing off some other poor bastard's $100 bill for two aspirins.)
The problem with health insurers isn't their profits (though that's a popular political talking point), but rather it is the part they've played in creating/enabling all the inefficiency in the current bureaucracy.
