Former Obama administration official Donald Berwick once called the Center for Medicare and Medicaid Innovation (CMMI) “the jewel in the crown of health-care reform.” The metaphor is apt: CMMI, more than any other aspect of Obamacare, is an imperial enterprise.

Congress established CMMI in the Obamacare statute with the goal of finding ways to reduce federal spending on medical care without diminishing its quality. That, of course, is the responsibility of Congress, which created the Medicare program and which alone bears responsibility for making legislative changes to it.
