The Obama administration on Monday said people hoping to enroll in health coverage for March 1 may have trouble applying by Saturday's deadline because of a planned 62-hour maintenance shutdown of a Social Security Administration computer system.

The U.S. Centers for Medicare and Medicaid (CMS), the lead Obamacare agency, said the shutdown will prevent applicants from verifying their Social Security numbers and other data through the federal website, HealthCare.gov. Those unable to enroll because of the outage can request special enrollment for coverage beginning March 1, CMS said.
