"Since enactment of the Affordable Care Act (ACA) in 2010, much of the attention in the policy community has been on modernizing Medicare’s traditional fee-for-service (FFS) program. Through Accountable Care Organizations (ACOs), larger “bundles” of payments to fee-for-service providers for episodes of care, and tests of pay-for-performance models, the hope is that the traditional Medicare model can be remade through sheer force of bureaucratic will. The stated intent is to find a way to pay for value, not volume.
These efforts may or may not bear much fruit, but, over the longer term, it’s not likely to matter much.
