Report: Insurers predict 'lots of chaos,' wealthy enrollees in Washington’s health exchange

In the second year of Washington's state-run exchange for health insurance, changes in premiums and the number of plans available for enrollees led to tweaks in how the Washington Health Benefit Exchange approached the process of enrollment this year.

That's just one of the findings in a report by the Urban Institute and the Robert Wood Johnson Foundation on health insurance exchange renewals in the second year of the Affordable Care Act's implementation. The report, which compares how the state exchanges are comparing to the federal marketplace, examines six states with exchanges to understand what the second year of the ACA looks like.
