Yesterday marked the beginning of open enrollment in the Health Care Marketplaces—the best chance for people who do not get coverage through their employer or programs like Medicare and Medicaid to get covered for the upcoming year. Last year, hospitals and health systems played a key role in getting the word out in their communities. As a result, nearly 12 million people enrolled in coverage for 2018, meaning they now have access to preventive care, critical treatments, and more affordable prescriptions.
