The right to know hidden financial incentives insurance plans offer doctors and hospitals to deny or withhold treatments. The right to get emergency-room care in a medical situation that a prudent layperson would consider a medical emergency. The right of consumers to an independent appeal process when an insurer refuses to pay. The right to have medical information kept confidential. Interestingly, the better insurers and HMO's already provide these.
Doctors can report ever greater infringement on their clinical judgment.
In fairness, some of these measures are legitimate tools to manage health-care dollars that are necessarily limited. It is certainly possible to conduct too many tests as well as too few. And there is indeed such a thing as unnecessary surgery. The idea is that there is a right way and a wrong way to treat patients, just as in the manufacture of widgets. The right way both maximizes patient wellbeing and conserves scarce resources.
