Health insurance exchanges will likely see a big enrollment boost next month and it's not only because that's when federal officials hope to have the HealthCare.gov website operating smoothly. "There is an avalanche coming," Bryce Williams, managing director for exchange solutions at benefits consulting firm Towers Watson, told NPR Shots. Based on years of experience with Medicare's open enrollment season, Williams says the Monday after Thanksgiving is the single busiest day for business. "People will have been thinking about this over the holidays and talking to family members, and they are going to feel an impetus to do something on that Monday; and there is going to be a huge crush," he said. What's more, the arrival of December means the quickly approaching deadline of Dec. 23 to obtain insurance, NPR Shots noted. Article
