Texas doctors opting out of Medicare at alarming rate

Houston Chronicle  "Two years after a survey found nearly half of Texas doctors weren't taking some new Medicare patients, new data shows 100 to 200 a year are now ending all involvement with the program. Before 2007, the number of doctors opting out averaged less than a handful a year."  What is the "Doc fix" ? "In the 1990s, President Bill Clinton and a Republican Congress passed a law cutting Medicare payments to doctors. The cuts ended up being bigger than policy makers first understood, so President George W. Bush and a Republican Congress overrode them in 2003. In the years since, both Republican and Democratic Congresses continued to override them."
