PY4 of Next Generation ACO Model RIFs Now Available

CMS is pleased to announce the availability of Next Generation Accountable Care Organization (NGACO) Model Research Identifiable Files (RIFs) for Performance Year 4. Two files are available for this performance year. The first file, the NGACO Beneficiary RIF, contains enrollment data for beneficiaries in the NGACO Model. A second file, the NGACO Provider RIF, contains identifying information about the providers participating in the NGACO Model. The Model consists of three initial performance years (2016-2018) and two optional one-year extensions (2019-2020).

The Center for Medicare and Medicaid Innovation's (CMMI) NGACO Model is an initiative for ACOs that are experienced in coordinating care for populations of patients. It allows these provider groups to assume higher levels of financial risk and reward than are available under the Medicare Shared Savings Program (MSSP). The goal of the Model is to test whether strong financial incentives for ACOs, coupled with tools to support better patient engagement and care management, can improve health outcomes and reduce expenditures for original Medicare Fee-for-Service (FFS) beneficiaries.
