Even though young adults can stay on their parents' plans until they're 26 years old, students increasingly are signing up for college-sponsored insurance. "Most of the schools we're tracking say they have had increases in enrollment in their student health plan over the last two to three years, despite the age 26 provision," Stephen Beckley, who runs health management firm Hodgkins Beckley Consulting, told USA Today. The company's annual study shows the healthcare reform law has slightly increased students' premiums for school-sponsored plans. From the 2011 to the 2012 school year, the average cost increased 9 percent at public colleges and almost 8 percent at private schools. But college-sponsored health plans still offer the best coverage at a low price for many students, especially if they don't qualify for subsidies through the federal health insurance exchange. Article
