More than 12.2 million people selected a plan through the Health Insurance Marketplaces during 2017 open enrollment, about 500,000 fewer than last year, according to a final report released today by the Centers for Medicare & Medicaid Services. More than 9.2 million people enrolled through HealthCare.gov, and the rest through the 12 state-based marketplaces. Three-quarters of enrollees selected a silver plan, 83% qualified for an advance premium tax credit and 58% for cost-sharing reductions. Consumers with an APTC reduced their monthly premium by an average $383 to $106. More than 3.8 million enrollees were new to the marketplaces. In the 38 states using HealthCare.gov in both 2016 and 2017, about half of returning consumers switched plans.
