The Centers for Medicare and Medicaid Services has announced 45 providers that are participating in the Next Generation accountable care organization model, up from an estimated 17 the year before.
For 2017, 28 new participants joined the Next Gen model, bringing the total number of participants to 45.
CMS Innovation Center's Next Generation ACO Model was designed to test whether strong financial incentives for ACOs can improve health outcomes and reduce expenditures for Medicare fee-for-service beneficiaries.
Provider groups in this model assume higher levels of financial risk and reward than are available under the shared savings program.
Next Generation is among the riskiest for providers, with some last year saying the metrics were too high a standard to reach the savings needed to earn payments.
The names of the 45 Next Gen ACOs were released Wednesday when CMS announced that over 359,000 clinicians would be participating in four alternative payment models.
APMs are one of two quality payment programs - the other being the merit-based incentive system, or MIPs - that satisfies implementation of the Medicare Access and CHIP Reauthorization Act, or MACRA.
CMS said that by the 2018 performance year it expects 25 percent of clinicians in the quality payment program will be participating in an advanced APM, and will be eligible to earn APM incentive payments.
The four APM qualifying models are the Medicare shared savings program, Next Generation ACO, comprehensive end-stage renal disease care model, and comprehensive primary care plus, or CPC+ model.
There are 572 ACOs across the shared savings program, Next Generation and the comprehensive end-stage renal disease model, CMS said. Of these, 131 ACOs are in a risk-bearing track.
Next Generation consists of three initial performance years and two optional one-year extensions.
An application portal for applications in the 2018 Next Gen ACO Model, along with a letter of intent due in May, will be open in March and also due in May.
