This brief examines continued changes in the uninsurance rate for nonelderly adults through September 2014, when the most recent round of the Health Reform Monitoring Survey (HRMS) was completed. Though the marketplace open enrollment period ended in April 2014, those who have since experienced a qualifying life event, such as marriage, divorce, birth of a child, or loss of coverage, have been eligible to apply for coverage through the marketplace during a special enrollment period. Also, coverage may change because enrollment in Medicaid is available to eligible adults any time during the year, and the nation’s ongoing economic recovery may cause gains in private coverage. Moreover, states’ continued processing of their Medicaid application backlogs may have led to increased Medicaid enrollment. Simultaneously, other factors may dampen coverage gains, such as a decline in coverage because some Marketplace plan enrollees failed to pay their premiums.
