In 2007, 8% of beneficiaries enrolled in a PDP chose one with some gap coverage. Among beneficiaries in MA-PD plans, enrollment in plans offering gap coverage was 33% (up from 27% in 2006). Premiums are significantly higher for plans with gap coverage. These plans are becoming less common as the gap closes. The fact that beneficiaries on Social Security Extra Help/LIS were never affected by the gap and the fact that many state pharmaceutical assistance programs protected middle income seniors in the gap are the reasons this gap benefit was never especially popular.
