Dr. Michael Ciampi took a step this spring that many of his fellow physicians would describe as radical.

The family physician stopped accepting all forms of health insurance. In early 2013, Ciampi sent a letter to his patients informing them that he would no longer accept any kind of health coverage, both private and government-sponsored. Given that he was now asking patients to pay for his services out of pocket, he posted his prices on the practice’s website.
