Manipulating P4P

Stanley Feld writes about P4P and how insurance companies are going to destroy the physician work force:

Just imagine the worst physician in a community figuring out what tests would give him a high rating and increase his income. He does the required tests routinely whether the patient needs them or not. He misinterprets those tests to the detriment of the patient. Yet he is rated the best doctor in the town. It is like a bizarre Fellini movie.
