March 31st marks the closing of the open enrollment period for private health insurance provided through the marketplaces. The Department of Health and Human Services has estimated that over 6 million people have signed up for health insurance coverage. Some people may qualify for a special extended enrollment period if they have had problems signing up for insurance coverage before the deadline. If you think you qualify but haven’t been notified, you can ask for a special enrollment period by calling the Marketplace Call Center at 1-800-318-2596 and letting them know your circumstances. The call center will ask a series of questions to see if you qualify. Make sure you have evidence that you’ve tried to enroll but were not successful.
