According to the WSJ:
Medicare utilization is roughly 50% higher than private health-insurance utilization, even after adjusting for age and medical conditions.
In other words, given two patients with similar health-care needs—one a Medicare beneficiary over age 65, the other an individual under 65 who has private health insurance—the senior will use nearly 50% more care.
Why?
People who have comprehensive health coverage like Medicare tend to use more care, and more expensive care — with no noticeable improvement in health outcomes — than those who have basic coverage or high deductibles.
Prof Mark Perry extends the observation, to partially explain why healthcare costs are so high … in general, folks have a decreasing amount of skin in the game (think deductibles and co-pays) … and when consumers are insulated from costs, they consume more … and more … and more.
The graph below tells the story.
