After a five-year contraction in employer health care spending growth, medical inflation in the United States is projected to rise to 6.8 percent in 2015, according to a new report today from PricewaterhouseCoopers LLC. The report, Medical Cost Trend: Behind the Numbers, projects that the stronger economy is now reaching the health sector, releasing a pent-up demand for care and services. Despite some higher utilization and the cost of expensive new cures, the higher expected growth rate in 2015 is modest compared with the double-digit annual increases seen throughout the late 1990s and early 2000s. It is still too early to determine whether the drive toward greater transparency and higher value will be able to temper the spending growth expected as millions of newly insured access the health care system, PwC's health industries leader said.
