You may think the Affordable Care Act (aka Obamacare) is all about health insurance. But there's much more to it than that. For instance, the law requires that most health plans provide "free" coverage for a slew of preventive screenings and services. That means no deductible, no co-payment, and no co-insurance on your part. The rule applies to all private plans, including individual, small group, large group, and self-insured plans. A few plans are exempt if they're "grandfathered" in, meaning they have made no changes to their benefits since 2010. That affects about one in four employees who receive healthcare coverage through their employers, but the number shrinks every year. Determining What's Covered Most covered services are based on recommendations from the U.S. Preventive Services Task Force (USPST), an independent panel of clinicians and scientists that reviews current medical data and makes recommendations regarding screenings. It's important to note that some of its recommendations differ from those of other medical organizations. For instance, the USPSTF recommends that women ages 50 to 74 receive a breast cancer screening every two years and states that women 75 and older no longer need screenings. The task force also makes no specific recommendation for women younger than 50, noting it should be a personal decision between a woman and her healthcare provider. However, the American Cancer Society recommends yearly mammograms starting at age 40 and continuing as long as the woman is in good health. So if you want a mammogram more often than the USPSTF recommends, you'll have to pay any deductibles and copays. Immunizations are based on recommendations from the Advisory Committee on Immunization Practices, a federal committee of immunization experts. You must receive the screenings and other preventive services from an in-network provider in order to receive them at no cost, unless no in-network provider is available.

If you are seeing your healthcare provider for something other than a preventive service, but you receive a preventive service during the visit (such as a flu shot, you may have to pay your portion for the office visit. If you are treated during an office visit because of the results of a recommended preventive service, such as a blood pressure screening, but are not there for the preventive service, you will probably have to pay your portion for the treatment.
