pretoria, south africa. it was inside a short time ago that a judge granted bail to olympic runner oscar pistorius, who is charged with murdering his girlfriend on valentine's day, so we will let you know when we see oscar pistorius. in the meantime, i think everybody's got a story about an expensive doctor's visit or hospital bill, but "time" magazine's new cover story "bitter pill, why amedical bill are killing us" breaks down the numbers. what they found is truly shocking. let me just give you one example. a patient was charged $199.50 for a troponin test. she is a year away from medicare. if she was a year older the same bill would have been $13.94. the prices are set by a computer called a charge master, and most hospital officials couldn't even really explain what it is other than that's how they've always done it. i want to bring in "time's" senior editor jeffrey klugger. fantastic piece.
