The U.S. Senate went on break this week, leaving doctors in limbo, waiting to know whether planned payment cuts for Medicare services will go through. If these 20 percent reductions pass, doctors may ditch their private practices and join up with hospitals, says Alfred Bove, a cardiology professor at Temple’s School of Medicine and a recent president of the American College of Cardiology. "In the cardiology world we think 40-50 percent of cardiology practices have already done that within the last year, seeing this problem coming down the line."
