What's wrong with how Medicare pays doctors

There are plenty of problems with Medicare, but patient input into pricing is not one of them. One of the comments on the article sums it up nicely:

"The information asymmetry between the doctor and patient is so great that a patient’s judgement about the value of a given treatment is meaningless. Not to mention that people are irrational actors. To go back to my pharmacy example: demand for cosmetic treatments is often less elastic than it is for treatments that will keep a person alive."
