Greetings! How do I make sure of no pre-existing condition restriction on health insurance when changing jobs?

I'm starting a new job soon, from private sector to fed gov't and presently have CareFirst Blue Cross Blue Shield.
--------------------
You will have a pre-existing if you have a 63 day lapse of coverage. So buy Cobra coverage for one month from the job you are leaving and then you'll only have a 60 day lapse and you'll be set. Or just to cover youself you can buy all 3 months until the new policy sets in.
