The Health Insurance Portability and Accountability Act (HIPAA) lays out the rules governing pre-existing rules. As ART66 stated above, you eed to have continious coverage, with no laps greater than 63 days. A wait period imposed by a new plan is not considered in that 63 day gap however. When you leave your current job, your insurance carrier will give you a certificate of prior coverage (HIPAA certificate) that will serve as proof of prior coverage. If your new plan tries to impose a wait period, due to a pre-existing condition, you can present that HIPAA certificate. They must offset the pre-existing wait period by the number of months of prior creditable coverage you had, as per the HIPAA certificate.
