When Can I Use My New Health Insurance? 
You can use a new health insurance plan on and after the effective date of the coverage . For example , if you have a July 1 , 2014 effective date , you can use your new coverage beginning on July 1 , 2014 and each day thereafter as long as the policy is in force . If you have purchased a policy with a future effective date and are still covered under an old plan , that policy would be providing your coverage until you reach the effective date of the new plan -LRB- and assuming you are terminating the other plan -RRB- . I hope the information is helpful - please feel free to contact me for help and if you have any other questions . Thanks very much .
