Methodology
Description
  • We examined whether enrollment in MA was associated with narrower racial and ethnic disparities in cost-related medical care barriers and cost-related dental care barriers as well as receipt of eye exams among near-poor Medicare beneficiaries. We further examined the extent to which racial and ethnic disparities were narrower among MA enrollees than TM enrollees who did and did not have private supplemental insurance.
