ACO Results for Performance Year 2017: Top 4 Insights


CMS released performance year 2017 results in August for the Medicare Shared Savings Program (MSSP). It was definitely a big year for ACOs. The following is a list of key insights from this year’s data file.


The ACO Success Rate Increased

The percentage of ACOs that are successful is probably the most cited statistic related to the program. In PY 2017, 162 out of 472 ACOs in the MSSP beat their minimum savings rate (MSR) and achieved shared savings, representing a success rate of over 34 percent. This represents an acceleration of the improvements in previous years. There was an even larger jump in the ACO success rate when measured by total beneficiaries (i.e. the percentage of beneficiaries in a “successful” ACO), indicating that larger ACOs had more success in PY 2017.

CMS Turned a Big Profit

For the first time ever, CMS clearly turned a profit in PY 2017 to the tune of about $314 million. A lot of time is spent discussing the total “gain” from the program, which is usually cited as the gain generated by successful ACOs. This measure excludes ACOs with higher costs than their benchmark. What matters to CMS is the total aggregate expenditure relative to the total aggregate benchmark, less the amount shared with ACOs.

It's worth noting that the CMS Office of the Actuary estimates that this simple approach understates the true impact of the program by as much as 60% due to spillover effect on non-assigned beneficiaries.


ACOs Performed About the Same On Average

Despite the dramatic increase in success rate and improvement to the CMS bottom line, ACOs themselves actually performed about the same in terms of generating revenue. Total shared savings was $781m in PY 2017, or $86.82 per beneficiary, which was actually a slight decrease from PY 2016. The decline was due to a decrease in shared savings per beneficiary attributable to successful ACOs, meaning ACOs who exceeded their MSR did so by less (and a lower percentage of the total gain was shared by CMS as well, although this had less of an impact). These factors were off-set by the significant increase in the number of successful ACOs.

Older ACOs Continue to Perform Better

  • For the first time, the 2013 cohort almost matched their 2012 counterparts in terms of shared savings per beneficiary.

  • Like the 2013 cohort before them, the 2014 group’s performance declined in its fourth year in the program, as the benchmark reset at the beginning of a new contract.

  • The 2015 cohort’s performance actually declined in year 3, after both the 2013 and 2014 vintages showed significant improvement in their third year.

  • The 2016 cohort showed significant improvement in year 2, continuing a well-established trend.

  • The new 2017 ACOs performed in line with previous new groups, on average, and significantly better than the unusually slow starting 2016 cohort.
