New regulations issued by the U.S. Department of Health and Human Services (HHS) show that many of the state laws restricting certified consumer assistance personnel from helping people get insurance may be invalid. In their latest blog post, Justin Giovannelli and colleagues at Georgetown University’s Health Policy Institute examine the 19 states that have limited the role of the Affordable Care Act’s health insurance navigators and explain how the new HHS rules shed light on the scope of state authority to regulate these assisters. Also listen to the New Directions in Health Care podcast about navigators.
