On November 22, 2017, the Centers for Medicare and Medicaid Services (CMS) announced updates to the Medicare Advantage Value-Based Insurance Design (MA-VBID) model
The model launched on January 1, 2017, at which time select MA plans in 7 states were permitted to offer varied benefit designs for enrollees diagnosed with specified clinical conditions.  In 2018, the model will expand to three new states and will add two clinical categories. Beginning in 2019, the V-BID model will expand to an additional fifteen new states for a total of 25 states, allow Chronic Condition Special Needs Plans to participate, and allow participants to propose their own systems or methods for identifying eligible enrollees.  
The MA-VBID model test aims to assess the utility of structuring consumer cost-sharing and plan elements to encourage the use of high-value clinical services and providers for beneficiaries with specified chronic conditions.  V-BID approaches have increasingly been used in the commercial market, and the inclusion of clinically nuanced V-BID elements may be an effective tool to improve the quality of care and reduce the cost of care for Medicare Advantage enrollees with chronic diseases.
