A new Kaiser Family Foundation analysis finds that average annual out-of-pocket prescription drug spending for workers and family members decreased from a recent high of $167 in 2009 to $144 in 2014. Most of the decline in out-of-pocket spending occurred between 2009 and 2012 and is likely due to generic substitution for popular drugs that lost patent protection. The decline in out-of-pocket-spending continued from 2012 to 2014 with nearly two-thirds of the decline during this…

A new Kaiser Family Foundation analysis finds about one in four people (24%) covered by large employer plans spent more than $1,000 out-of-pocket on health care in 2015, an increase of seven percentage points from 17 percent in 2005. About 1 in 10 people in such plans (12%) paid more than $2,000 out-of-pocket in 2015, a distribution that mirrors the distribution of overall health spending, according to the new analysis of claims data. Dollar…
