The latest figures show that about 30 million Americans are uninsured for health care. That is Americans of all ages.
How then can lowering the Medicare eligibility age to 60 from age 65 provide health care coverage for an additional 23 million people?
About 8% of people age 60-64, or 1.6 million people, are uninsured and could newly gain Medicare coverage under this policy. Among uninsured adults age 60-64, most (66%) are eligible for financial assistance for coverage through the ACA marketplace or Medicaidhttps://www.kff.org/health-reform/issue-brief/coverage-implications-of-policies-to-lower-the-age-of-medicare-eligibility/
The great majority of individuals age 60-64 already have health insurance so for most it is changing one coverage for any other and for many it would mean a lower level of coverage and/or higher out-of-pocket costs and perhaps premiums.
