When the open enrollment period for the New Mexico Health Insurance Exchange kicks off Sunday, one carrier with thousands of patients won’t be ready to offer plans through the state’s online portal. New Mexico Health Connections has announced that its insurance offerings on the exchange will be delayed by one or two weeks as some technical glitches are resolved. Dr. Martin Hickey, chief executive of the nonprofit insurance cooperative, said the plans should be available by Nov. 15. Hickey said the problem occurred as the co-op was uploading templates to the federal healthcare.gov website, where New Mexicans seeking individual coverage must go to enroll in a policy.
