SACRAMENTO, Calif. (AP) — California's health insurance exchange will institute a "grace period" for those who attempted to get coverage yesterday but were unable to sign up. California's health insurance exchange had been being inundated with consumers who were attempting to sign up for coverage and beat the deadline to have a policy in place by the first of the year. Covered California, which operates the state's marketplace, did not extend yesterday's deadline, as the Obama administration did for the 36 states using the federal health insurance exchange. But as high volume overwhelmed its website and call centers, the agency offered breathing room for people who were attempting to enroll. Executive Director Peter Lee told reporters that Covered California will institute a "grace period" for those who attempted to get coverage yesterday but were unable to sign up. He did not commit to a date when that grace period would end but said the agency's goal was to have a policy in place for everyone who tried to get one by the deadline. He also said the number of Californians signing up for an individual health insurance policy through the exchange had topped 400,000.
