"[HHS] now expects 11 million uninsured Americans to obtain coverage next year, down from about 22 million projected a year ago ... It said healthcare spending would rise 6.1 percent in 2014, partly due to the implementation of Obamacare, compared with a previous projection of an increase of 7.4 percent.... Over the longer term, the report said healthcare spending growth would accelerate to 6.5 percent by 2022, when the industry would hit the $5 trillion mark and represent 19.9 percent of gross domestic product. Obamacare's contribution to spending is expected to diminish after 2015 as retiring baby boomers shift the momentum toward the Medicare program for the elderly and disabled."
