The Effect of the Medicare Advantage Value-Based Insurance Design Model Test on Utilization in 2017

In 2015, the Centers for Medicare and Medicaid Services announced the Medicare Advantage (MA) Value-Based Insurance Design (VBID) model test, which allows MA insurers to use flexible benefit design strategies, such as reduced cost-sharing, to encourage beneficiaries with chronic disease to use high-value care. During the first year of implementation (2017), nine MA insurers offered VBID in 45 health plans to a total of 96 053 eligible beneficiaries. We used MA encounter data to estimate the impact of VBID on health services utilization in 2017 using a difference-in-differences research design. We found that VBID increased use of 10 out of 18 targeted services, and led to general increases in primary care visits, specialty care visits, and drug fills across eligible beneficiaries. The model was also associated with increases in ambulatory care sensitive inpatient and emergency department visits, an unanticipated effect that may be temporary. Overall, our findings suggest that VBID successfully increased the use of high-value services among eligible MA beneficiaries, an important first step along the pathway to better chronic disease management, lower spending, and improved beneficiary health.
