"It costs $13,660 for an American to have a hip replacement in Belgium; in the U.S., it's closer to $100,000."

"Americans pay more for health care than people in many other developed countries, and Elisabeth Rosenthal is trying to find out why. The New York Times correspondent is spending a year investigating the high cost of health care. The first article in her series, "Paying Till It Hurts," examined what the high cost of colonoscopies reveals about our health care system; the second explained why the American way of birth is the costliest in the world; and the third, published this week in The Times, told the story of one man who found it cheaper to fly to Belgium and have his hip replaced there, than to have the surgery performed in the U.S."

"Rosenthal has also been investigating why costs for the same procedure can vary so much within the U.S. — by thousands of dollars, in some cases — depending on where it's being performed. Before becoming a journalist, Rosenthal trained as a doctor and worked in the emergency room of New York Hospital, now part of New York-Presbyterian Hospital."
