Actuaries at the Centers for Medicare & Medicaid Services, a government agency, have just updated their estimate of future health spending:
For 2018 and beyond, both Medicare and Medicaid expenditures are projected to grow faster than in the 2016–17 period, and more rapidly than private health insurance spending, for several reasons. First, growth in the use of Medicare services is expected to increase from its recent historical lows (though still remain below longer-term averages). Second, the Medicaid population mix is projected to trend more toward somewhat older, sicker, and therefore costlier beneficiaries. Third, baby boomers will continue to age into Medicare, with some of them dropping private health insurance as a result. And finally, growth in the demand for health care for those with private coverage is projected to slow as the relative price of health care—the difference between medical prices and economywide prices—is expected to begin gradually increasing in 2018 and as income growth slows in the later years of the projection period.
