The Impact Of Medicare On Access To And Affordability Of Health Care.

Medicare pays for roughly one in four physician visits in the United States, yet a rigorous understanding of how Medicare currently affects access to and affordability of care for its enrollees is unavailable. Using data from the Medical Expenditure Panel Survey-Household Component and the National Health Interview Survey, I tested for changes in access to care and affordability around age sixty-five, when most people gain eligibility for Medicare. I found that Medicare eligibility is associated with a 1.5-percentage-point reduction in reports of being unable to get necessary care (a 50.9 percent reduction compared with the percentage at age sixty-four) and a 4.1-percentage-point (45.3 percent) reduction in not being able to get needed care because of the cost. Recently, policy makers have proposed various ways of extending Medicare coverage. These results suggest that incremental Medicare expansions could have positive access and affordability benefits for enrollees compared with the insurance options available to them before they turn sixty-five.
