ObamaCare's secret success

So what aspects of Obamacare might be causing health costs to slow?

The program now penalizes hospitals if many of their patients end up being readmitted soon after being released — an indicator of poor care — and readmission rates have, in fact, fallen substantially. Medicare is also encouraging a shift from fee-for-service, in which doctors and hospitals get paid by the procedure, to “accountable care,” in which health organizations get rewarded for overall success in improving care while controlling costs.

Furthermore, there’s evidence that Medicare savings “spill over” to the rest of the health care system — that when Medicare manages to slow cost growth, private insurance gets cheaper, too.
