Paul Freeman drove 600 miles last year to save himself — and his employer — thousands of dollars on his surgery. Freeman's insurer covered his travel costs and the entire bill because a medical center in Oklahoma City could remove the loose cartilage in his knee for about 70 percent less than a hospital closer to Freeman's Texhoma, Okla., home. At first, the community bank CEO hesitated because he thought the lower price would mean lower quality. But he knew if he didn't make the roughly 10-hour roundtrip trek, he'd pay about $5,000 out of pocket.
