Basic Alternative (BA) benefits are an alternative version of the standard benefits of a Part D Drug plan. Basic Alternative benefits may have a smaller annual deductible (or no deductible at all), and may have different cost-sharing such as tiered cost-sharing for drugs and changes to the initial coverage limit.

TIP: There are four benefits types for Part D drug plans: Defined Standard (DS), Actuarially Equivalent (AE), Basic Alternative (BA), and Enhanced Alternative (EA). Learn more about the Medicare Part D Plan Benefit Types.
