Impact of Medicare SELECT on cost and utilization in 11 states.

ABSTRACT

In this article, the authors evaluate the cost and utilization effects of the SELECT implementations in 11 States. In particular they compare the before-and-after enrollment experiences of Medicare beneficiaries newly enrolled in SELECT plans with the experiences of those newly enrolled in traditional medigap plans. Using Medicare claims data for 1991 through 1994, the authors find that Medicare SELECT increased costs in five States, decreased costs in three States, and had no effect in three States. Cost increases were generally related to Part B utilization.
