Medicare Accountable Care Organizations Are Not Associated With Reductions in the Use of Low-Value Coronary Revascularization.

ABSTRACT:

Background

Because specialty care accounts for half of Medicare expenditures, improving its value is critical to the success of Medicare accountable care organizations (ACOs) in curbing spending growth. However, whether ACOs have reduced low-value specialty care without compromising use of high-value services remains unknown.

We then determined the provider groups who cared for the cohorts, distingu
