Here is an example of fraud as a reason healthcare cost are so high in the US:
Hill-Rom settles Medicare fraud lawsuit - BusinessWeekHill-Rom Holdings Inc., a medical-equipment company in Indiana, agreed Tuesday to pay nearly $42 million to settle a government lawsuit that alleged Medicare fraud.
The government had accused the company of knowingly submitting false claims to Medicare from 1999 to 2007 for bed support surfaces meant to treat pressure ulcers and bedsores. According to the charges, Hill-Rom asked "numerous and repeated" times for payment from Medicare for patients who no longer qualified for it, including patients who had died or were no longer using the equipment.
According to the charges, Hill-Rom would automatically bill Medicare for "long periods of time," "without making any reasonable effort to determine if the patients for whom it submitted the claims continued to meet Medicare conditions for payment."
