An updated chart collection explores prescription drug spending for people who are covered by large employer health plans.

The analysis finds that about 4% of people with employer coverage have prescription drug costs totaling $5,000 or more, and about 3% have out-of-pocket prescription drug costs exceeding $1,000. Enrollees with total prescription drug spending exceeding $5,000 are more likely to be older and have serious health conditions.

The chart collection is part of the Peterson-KFF Health System Tracker, an online information hub dedicated to monitoring and assessing the performance of the U.S. health system.
