How well do Americans understand their health coverage?

Data from two surveys are used in this DataWatch to explore Americans' understanding of their health insurance. First, data from a national survey of consumers are used to examine if people with private health insurance correctly report their coverage for six services. Second, information from an evaluation of a pilot project of subsidized insurance in New York is used to investigate how well newly insured persons understand their coverage. Based on these surveys, almost all privately insured people understand the basic elements of their insurance plans but underestimate their coverage for mental health, substance abuse, and prescription drug benefits and overestimate their coverage for long-term care. People who are newly insured in physician networks or health maintenance organizations seem uncertain about what services their plan covers and restrictions on their choice of hospitals.
