Now and again there’s a real world case that reminds you why the only solution for keeping private health plans is managed competition, with the emphasis on managed. Remember as you read this story that Alain Enthoven always said that there should be community rating, with standardized benefits between plans and risk adjustment between them to override the impact of chance-driven uneven risk selection.
So the story (hat-tip to Rick Byrne for this) begins with Part D, which allows significant disparity in benefits between plans—something that it’s claimed causes few problems for enrollees. What happens next is that one plan with particularly rich benefits finds that it is adversely selected against. But this doesn’t become clear until late in 2006. Meanwhile Sierra Health Services, a Nevada based for-profit HMO with a pretty good record at cost containment, thinks that it can launch a PDP (stand alone drug plan) that covers the donut hole and has rich benefits. It has to file the paper-work by mid-2006, it charges a hefty premium and it waits for the money to roll in. 42,000 seniors sign up.
