Researchers for The Commonwealth Fund found that a small and declining share (7%) of Medicare Supplement plans (also known as Medigap plans) cover only 12% of all Medigap enrollees and provided additional benefits (such as dental, vision, and hearing) not covered by traditional Medicare in 2020. Enrollment in Medigap plans is growing at more than 4% annually since 2016 and Congress is considering increasing access to these additional benefits. The researchers found the additional benefits were concentrated in only a few Medigap plans and that some 65%of Medigap enrollees who could get these benefits were enrolled in Medigap Plan G.
