In week one of Affordable Care Act (ACA) Open Enrollment for 2019, 371,676 people selected plans using the HealthCare.gov platform. As in past years, enrollment weeks are measured Sunday through Saturday.  Consequently, week one was only three days long this year – from Thursday to Saturday.

Every week during Open Enrollment, the Centers for Medicare & Medicaid Services (CMS) will release enrollment snapshots for the HealthCare.gov platform, which is used by the Federally-facilitated Exchanges, the State Partnership Exchanges, and some State-based Exchanges. These snapshots provide point-in-time estimates of weekly plan selections, call center activity, and visits to HealthCare.gov or CuidadoDeSalud.gov.

The final number of plan selections associated with enrollment activity during a reporting period may change due to plan modifications or cancellations. In addition, the weekly snapshot only reports new plan selections and active plan renewals and does not report the number of consumers who have paid premiums to effectuate their enrollment.
