Since the passage of the Affordable Care Act (ACA), insurers can no longer deny coverage to consumers based on a preexisting condition or adjust premiums based on health status. As a result, insurers run the risk of being undercompensated for the care of high-need, high-cost patients. To guard against this, insurers may use subtle means to avoid sick patients and attract healthier, less-expensive ones-- a practice known as risk selection. To protect patients and ensure that insurers' compensation is linked to enrollees' health risk, policymakers need to understand the complexities of risk selection and implement strategies to reduce it. European countries have been using health exchanges for 20 years and offer valuable insight for the United States.
