Waiting period
(b) Waiting period defined. For purposes of this part, a waiting period is the period that must pass before coverage for an individual who is otherwise eligible to enroll under the terms of a group health plan can become effective. If an individual enrolls as a late enrollee (as defined under 54.9801-2) or special enrollee (as described in 54.9801-6), any period before such late or special enrollment is not a waiting period.
