If your health insurer pays too much for a claim, you might think that would be a good kind of problem. But it could turn out to be more of a headache than a windfall.
Just ask Lisa Dowden, who had gastric bypass surgery three years ago. In September, the 51-year-old lawyer got a bill from her insurer claiming she owed more than $9,100 because it had overpaid for the services of the surgeon who assisted on her operation.
Arkansas Gov. Mike Beebe speaks about expanding Medicaid during a speech to the Arkansas State Chamber of Commerce in Little Rock, Ark., on Nov. 14. The federal government hasn't set a deadline for states to decide on their Medicaid expansion plans.

Pulling out a porcupine quill is painful and slow, as many a dog discovers to its dismay after tangling with the big rodent. But those tenacious quills are inspiring efforts to develop better medical devices, including less painful needles.

Just as the name implies, Clostridium difficile is a difficult pathogen to beat. It causes a nasty infection in your gut, and it's often resistant to many antibiotics.
But C. difficile got even more troublesome about 10 years ago when a particularly virulent form of the bug cropped up in hospitals across the U.S and was no longer vulnerable to one of the most common classes of antibiotics.
