Washington's $10 billion search for healthcare's next big ideas

The Affordable Care Act was supposed to mend what President Barack Obama called a broken health care system, but its best-known programs — online insurance and expanded Medicaid for the poor — affect a relatively small portion of Americans.

The law created the Center for Medicare and Medicaid Innovation to launch experiments in every state, changing the way doctors and hospitals are paid, building networks between caregivers and training them to intervene before chronic illness gets worse.
