It is no secret that the growth of federal health care spending is key to the government’s long-term fiscal outlook. With evidence growing that at least some portion of the recent slowdown in health care cost growth represents structural changes in the health care system, the Congressional Budget Office (CBO) revised downward their estimates of health care spending over the coming years from their last Long-Term Budget Outlook in 2012. Despite improved projections in the near term, however, CBO’s projected long-term growth rates remain nearly unchanged and still far in excess of per capita economic growth. Moreover, the short-term gains actually erode over time due to increased projections of longevity.
In fact, while spending on Medicare is now estimated to be 4 percent lower over the next decade than it was last year, CBO actually increased its projections of program growth after 2023 (from an average annual rate of 6.4% from 2023-2050 to 6.5%). Even within a decade, though excess cost growth (the per beneficiary growth above economic growth per capita) for Medicare is expected to average only 0.3 percent (in part due to the effects of the 24 percent physician payment cut dictated by the Sustainable Growth Rate formula), it is expected to rise back to 1.4 percent by 2023, which has been a more typical level in the past.
Part of the explanation is that CBO now expects higher per beneficiary spending growth in the 2020s and only slightly lower growth thereafter. Looking at the causes of the recent slowdown, CBO explains that “even the portion of the recent slowdown that reflects structural changes in payment mechanisms or in how care is delivered may represent [a] one-time downward shift in costs rather than a persistent reduction in the growth rate.”
