Even employees covered by an employer-sponsored health plan remain confused about the benefits that are free of charge to them under health care reform law. But employers say that they often don’t have the resources or effective communications tools to fully explain these benefits to the workforce.

This finding emerged from a small sample study by the Midwest Business Group on Health, which surveyed 53 workplaces, more than half of which had 5,000 or more employees in their plans.

The survey indicated that progress is being made: 62 percent said they were aware of all the free services, which include vaccinations, maternity and pregnancy related services, pediatric services and others. But another 36 percent admitted they weren’t aware of the full spectrum of these free benefits. (Just 2 percent pleaded complete ignorance of the benefits.)
