I'd expect that most of the benefits of health care are not being measured here. For example, I don't see any mention of cosmetic effects (i.e. that leg you broke as a kid left you with a huge lump where the bone healed unevenly cause you set it yourself, etc) or of changes in ambulative ability.
Additionally, it is not measuring how improved health care is offsetting the much more unhealthy living practices of today's person vs. a century or two ago. People living today in civilized countries are for the most part in far worse condition in terms of physical fitness. People also are far more likely to die of traumatic accidents or drug use. The healthier people take more risks. The most dangerous time to die of a car accident is at age 16, which puts a nice damper on the stats long before one reaches old age. This blip is a recent phenomenon.
Moreover, I don't see how you can look at the differences in average life expectancy from country to country without seeing some definite benefit to modern health care. The effects on the infant mortality rates alone are phenomenal.

You are forgetting that the group "Medicare patients" already asserts a filter to a specific set of demographics which could very well gain little from improved health care, while the rest of the population may see significant benefits.
