CIGNA Corp. will be offering free coupons to consumers who take an online course that explains how the U.S. health care system works.

CIGNA, Philadelphia, has posted the Web course at http://www.cigna.com/learn4yourhealth

The course offers 5-minute sessions on health care and health finance topics. Participants can get incentives after completing each session. The coupons pay for purchases from restaurants and a variety of online stores, such as SportsAuthority.com and ShopPBS.org.

CIGNA clients may be able to offer employees a co-branded version of the course, the company says.
