In most states across the country, the open enrollment period for 2019 began on November 1 and will end on December 15, 2018. As we near the halfway point for enrollment—at least for the states with a federal marketplace—recent federal data suggests that enrollment in Affordable Care Act (ACA) marketplace plans is lagging relative to last year.

In its “week 2” enrollment snapshot, the Centers for Medicare and Medicaid Services (CMS) announced that nearly 1.2 million consumers selected a plan between November 1 and November 10 in the 39 states that use HealthCare.gov. Of these consumers, about 275,000 were new consumers while about 901,000 were renewing their coverage from last year. This reflects a significant increase from the first three days of open enrollment when about 371,000 consumers selected a plan.

“Week 2” plan selections are down by about 302,000 consumers relative to last year. This can be read as between an 8 to 13 percent decline in plan selections compared to last year, when a total of 11.8 million consumers in all 50 states and DC selected or were automatically reenrolled in a marketplace plan. Enrollment remained largely stable from 2017 to 2018 despite a shortened open enrollment period and significant cuts to advertising and navigator funding.

This year, however, brings additional changes that could be contributing to what is, at least so far, depressed enrollment through HealthCare.gov. These changes include repeal of the individual mandate penalty; 2019 is the first year that consumers will no longer pay a penalty for being uninsured under the ACA. In addition, new federal rules are enabling expanded access to non-ACA plans (such as short-term, limited-duration insurance and association health plans). These non-ACA plans typically have a much lower premium than ACA plans and could lure consumers away from the marketplace.

It is too early to tell if the reduced enrollment trend will hold and if this pattern will continue. Enrollment may increase significantly before the December 15 deadline, and millions of Americans will enroll in coverage before the end of the year.

The declines are, however, significant. The former chief marketing officer for HealthCare.gov recently noted that the data “should be a wake-up call to everyone who cares about people having health care … on the need to step up efforts to raise awareness.” CMS intends to release enrollment snapshots on a weekly basis. Each snapshot also includes point-in-time estimates of call center activity and visits to HealthCare.gov and CuidadoDeSalud.gov, among other data.

The new open enrollment data comes at a time when the uninsured rate continues to remain steady. Data from the National Center for Health Statistics—in reports both from late August and November—shows that the uninsured rate of about 8.8 percent for 2018 remains largely unchanged from 2017. Although there was not a significant shift from 2017 to 2018, there has been a sizable drop in the uninsured rate since the ACA was enacted in 2010. Between 2010 and the first six months of 2018, the uninsured rate dropped from 16 percent (48.6 million people) to 8.8 percent (28.5 million people).
