But ACOs could pave the way for more significant cost-cutting based on competition.
By KEN TERRY
The Medicare Shared Savings Program (MSSP), it was revealed recently, achieved a net savings of $314 million in 2017. Although laudable, this victory represents a rounding error on what Medicare spent in 2017 and is far less than the growth in Medicare spending for that year. It also follows two years of net losses for the MSSP, so it’s clearly way too soon for anyone to claim that the program is a success.
The same is true of accountable care organizations (ACOs). About a third of the 472 ACOs in the MSSP received a total of $780 million in shared savings from the Centers for Medicare and Medicaid Services (CMS) in 2017 out of the program’s gross savings of nearly $1.1 billion. The other MSSP ACOs received nothing, either because they didn’t save money or because their savings were insufficient to qualify them for bonuses. It is not known how many of the 838 ACOs that contracted with CMS and/or commercial insurers in 2016 cut health spending or by how much. What is known is that organizations that take financial risk have a greater incentive to cut costs than those that don’t. Less than one in five MSSP participants are doing so today, but half of all ACOs have at least one contract that includes downside risk.
As ACOS gain more experience and expand into financial risk, it is possible they will have a bigger impact. In fact, the ACOs that received MSSP bonuses in 2017 tended to be those that had participated in the program longer—an indication that experience does make a difference.
However, ACOs on their own will never be the silver bullet that finally kills out-of-control health spending. To begin with, 58 percent of ACOs are led by or include hospitals, which have no real incentive to cut payers’ costs. Even if some hospitals receive a share of savings from the MSSP and/or private insurers, that’s still a drop in the bucket compared to the amount of revenue they can generate by filling beds instead of emptying them. So it’s not surprising that physician-led ACOs are usually more profitable than those helmed by hospitals.
