Easy Enrollment Act of 2018 This bill amends the Patient Protection and Affordable Care Act to shift the annual open enrollment period for health care exchanges. Beginning with calendar 2020, the annual open enrollment period must begin on a date set by the Department of Health and Human Services and must end on April 15 of that calendar year. Under current law, for benefit years beginning on or after January 1, 2018, the annual open enrollment period begins on November 1 and ends on December 15 of the calendar year preceding the benefit year.
