Healthcare is the largest, fastest growing, and most complex industry in the world. The U.S. healthcare system accounts for more than $2.5 trillion in annual expenditures, which is nearly 20% of our nation’s Gross Domestic Product (GDP). According to economists in the Office of the Actuary at the Centers for Medicare and Medicaid Services (CMS), spending is projected to grow at an annual average rate of 5.8% through 2020, which is 1.1% higher than our nation’s projected GDP growth. By 2020, healthcare spending is projected to exceed $4.5 trillion.
