There was recently a NY Times blog post "Getting Old is Expensive" regarding a subject I have covered for many years in presentations regarding Medicare, Aging Wisely and planning ahead--the cost of healthcare in later years. Very few people think about this stuff ahead of time...why would you? We're all busy dealing with our current health insurance, employment, etc. So, people generally know Medicare exists (and often seem to have the impression it will take care of everything with little/no cost) but rarely understand all of it's working parts, costs, etc.
As this article quotes as recent study and has been shown in studies for a # of years, out of pocket/uncovered costs from 65 til death usually rank in the $250,000 range. Check out our Medicare Fact Sheet for some info. on the many premiums, copays and deductibles of the various parts of Medicare for the primary costs:
