Why has Medicare spending per beneficiary stopped growing?
Core argument: Medicare spending per beneficiary has nearly leveled off over more than a decade, a slowdown obscured by the growing number of enrollees as baby boomers age.
Spending per Medicare beneficiary has nearly leveled off over more than a decade. The trend can be a little hard to see because, as baby boomers have aged, the number of people using Medicare has grown. The reason for the per-person slowdown is a bit of a mystery. Some of the reductions are easy to explain. The Affordable Care Act in 2010 reduced Medicare’s payments to hospitals and to health insurers that offered private Medicare Advantage plans. Congress also cut Medicare payments as part of a budget deal in 2011. But most of the savings can’t be attributed to any obvious policy shift. Economists at the Congressional Budget Office described the huge reductions in its Medicare forecasts between 2010 and 2020. Most of those reductions came from a category the budget office calls “technical adjustments,” which it uses to describe changes to public health and the practice of medicine itself.
