A nonpartisan Kaiser Family Foundation study found raising the eligibility age of Medicare to 67 would save billions of dollars.
However, this would up costs to people ages 65 and 66. It would also raise costs for employers because people would work longer to keep their medical coverage.
Medicare recipients would also pay some 3 percent more because the youngest seniors wouldn't even be in the pool.
The study also states that even people under 30 would be hit, because seniors aged 65 and 66 would be in the insurance pool, raising costs.
Medicare covers 47 million elderly and disabled people. It is widely seen as financially unsustainable in the long run.
Raising the eligibility age is among the leading fixes under discussion.
