Nearly 11.8 million people actively or automatically enrolled in a health plan through or a state-based exchange during open enrollment for 2018, according to a final report released yesterday by the Centers for Medicare & Medicaid Services. That’s about 400,000 fewer than in 2017, when the open enrollment period was more than a month longer. More than 8.7 million people enrolled through, and the rest through the 12 state-based marketplaces. Nearly three-quarters of enrollees selected a silver plan, and 85% who enrolled through qualified for an advance premium tax credit. The average monthly premium for consumers with an APTC was $89, versus $522 for those without an APTC. More than 3.2 million enrollees were new to the exchanges.
