More people looking to buy health insurance say they would shop for coverage through a health insurance exchange if they had the opportunity, according to a J.D. Power and Associates health plan study released Tuesday.

A majority of health plan members who purchase insurance on their own say they would likely use one of the state health insurance exchanges (55 percent), while 39 percent of those covered under an employer-sponsored program indicate they would shop for insurance through an exchange if it were available.

And more, the study finds there's an increased level of interest in state-sponsored health insurance exchanges compared to last year. In 2012, 37 percent of health plan members say they wouldn't likely use an exchange, compared with 50 percent in 2011 who expected to continue obtaining coverage at work.
