The chilling effect is well stated here:

The practice of medicine is a calling and as such, my colleagues and I have endured more unfair revenue cuts than most businesses would have endured. Yet, a medical practice is also a small business, and there are limits to how much we can endure. We are now at the point where further cuts are not survivable. Just like any small business, our revenue has to exceed costs in order to survive. Despite everything that I have been able to do to cut costs, the margin of profit is now thin, and the proposed greater than 10 percent cut will put us out of business. The only option will be to downsize the practice and stop seeing all Medicare patients. I would hate this, but it will be the only option I have if Congress does not reverse the proposed cuts.
