The Centers for Medicare and Medicaid Services (CMS) changes to the benchmark methodology for accountable care organizations (ACOs) entering a renewal Medicare Shared Savings Program (MSSP) agreement period in 2017 and thereafter. The 2017 methodology introduced a regional adjustment, where an ACO’s historical expenditures are adjusted upward or downward based on how their costs compare to regional expenditures on a risk-adjusted basis. Because the risk adjustment depends on an ACO’s benchmark period risk scores, accurate and complete diagnosis coding during the benchmark period now has a significant influence on the calculation of the ACO’s benchmarks in future performance years.
CMS uses benchmark year (BY) 3 risk scores for the calculation of the regional adjustment, scores that are based on diagnoses from claims incurred in BY2. MSSP ACOs anticipating renewals in 2020 need to be working this year (2018) to ensure accurate and complete coding. Similarly, 2019 is the critical year for 2021 renewals.
In this paper, Milliman’s Jonah Broulette, Noah Champagne, and Kate Fitch explain how BY3 risk scores affect the benchmark calculation for MSSP renewals, present an overview of the prior and new risk adjustment calculations in MSSP, and illustrate how the change can affect an ACO’s benchmark under various scenarios.
The Medicare Access and CHIP Reauthorization Act (MACRA) makes significant changes to the Medicare payment system by introducing a quality-based payment model. While MACRA primarily affects Part B clinicians, there are numerous implications that Medicare Advantage (MA) plans should consider. A strategic approach can help MA plans understand and respond to the legislation.
In the article “MACRA and Medicare Advantage plans: Synergies and potential opportunities,” Milliman actuaries explore the answers to the following questions:
• How will MACRA affect MA plans’ provider payments?
• What synergies exist between MACRA’s quality scoring and the MA Stars quality program?
• How can MA plans help providers achieve Qualifying Participant (QP) status?
• What incentives exist under MACRA for providers to improve risk score coding?
• How are MA plans in the market responding to MACRA?

The Department of Health and Human Services (HHS) is striving to link 50% of Medicare payments to alternative payment models by 2018. One of the primary alternative payment models offered to Medicare providers is the Next Generation Accountable Care Organization (NGACO). Due to the potential large risk exposure for organizations considering this model, they should work with an actuary to understand the critical elements driving financial success (or failure). In this article, Milliman’s Charlie Mills, Cory Gusland, and Noah Champagne identify five key financial considerations that all ACOs should review before committing to the program. The considerations are ranked by the authors’ perceived importance, with one being the most important.
5. ACO’s CY2014 experience is the baseline for the first three performance years
4. Risk score changes are capped at 3% from the baseline year to each performance year
3. First dollar savings and losses
2. The 2016 benchmark trends are likely understated
1. In order to achieve savings, participants must outperform trended baseline less discount
