Milliman: 5 Key Drivers of Savings in MSSP ACOs

1. An ACO’s benchmark year 3 (BY3) regional efficiency factor (defined as the ACO’s BY3 expenditures divided by the risk-adjusted expenditures in its region)
2. Having a benchmark significantly above costs in benchmark year 3 (BY3), the most recent benchmark year
3. ACOs that selected tracks with downside risk
4. ACOs with few specialists and hospitals on their participant lists
5. Higher rates of primary care evaluation and management (E&M) visits and lower rates of unplanned inpatient hospital admissions
