Forecast Summary
Major Findings for National Health Expenditures: 2017-2026

(From Centers for Medicare and Medicaid Service actuaries. Website: https://www.cms.gov/Research-Statistics-Data-and-Systems/Statistics-Trends-and-Reports/NationalHealthExpendData/Downloads/ForecastSummary.pdf, accessed February 12, 2019.)

• Under current law, national health spending is projected to grow at an average rate of 5.5
  percent per year for 2017-26 and to reach $5.7 trillion by 2026. While this projected
  average annual growth rate is more modest than that of 7.3 percent observed over the
  longer-term history prior to the recession (1990-2007), it is more rapid than has been
  experienced from 2008-16 (4.2 percent).
• Health spending is projected to grow 1.0 percentage point faster than the Gross Domestic
  Product (GDP) per year over the 2017-26 period; as a result, the health share of GDP is
  expected to rise from 17.9 percent in 2016 to 19.7 percent by 2026.
• Projected national health spending and enrollment growth over the next decade is largely
  driven by fundamental economic and demographic factors: changes in projected income
  growth, increases in prices for medical goods and services, and enrollment shifts from
  private health insurance to Medicare related to the aging of the population.
• Among the major payers for healthcare, growth in spending for Medicare (7.4 percent
  per year) and Medicaid (5.8 percent per year) are both substantial contributors to the rate
  of national health expenditure growth for the projection period. Both trends reflect the
  impact of an aging population.
• The recent enactment of tax legislation that eliminated the individual mandate is expected
  to lead to a reduction in the insured rates. Economic factors, such as projected GDP
  growth and employment trends, are the primary factors contributing to a slight projected
  decline in the insured share of the population from 91.1 percent in 2016 to 89.3 percent in
  2026.
