Three recent negative critiques of the Medicare "Doc Fix":
"House 'Doc Fix' Bill Makes Things Worse, Medicare Analysis Finds" (Chris Jacobs, Wall Street Journal)
"Medicare Doc Fix Bill Is IPAB-Lite" (David Hogberg, Daily Caller)
"Medicare fix needs fixing" (Theodore Marmor, Philadelphia Inquirer)
In particular, the Hogberg piece notes the perverse incentives that will pressure doctors skimp on care to patients as part of cost containment. But all three are worth reading.
