Since the federal HIPAA protections only allow a 63 day gap between old and new health coverage, retaining the six month health coverage credit through AB 1672 is important for individuals with pre-existing conditions. You will need to retain your previous coverage so that there is not a gap in coverage for more than 180 days to use AB 1672. If you fulfill these requirements, you can enroll in new coverage without a pre-existing condition exclusionary period.
An open enrollment period is the annual period of time that you are allowed to make changes to your benefits. During this time period you are allowed to change, add or delete coverage.
