Generally, an enrollee may only cancel an enrollment during an open season. Exceptions: You may cancel your dental and/or vision enrollment if:

(a) You are an enrollee and transfer to an eligible position with a Federal agency that provides dental or vision coverage with 50 percent or more employer-paid premiums and you enroll in that program.

(b) You are an enrollee and you or your spouse deploy to active military duty.

(c) You are an enrollee or sponsor who does not pay premiums on a pre-tax basis, identified at § 894.403(b), and during the course of your enrollment, you become eligible for Department of Veterans Affairs (VA) dental or vision benefits. If you cancel a self plus one or self and family enrollment, as sponsor, you must notify your family members of changes in your enrollment pursuant to § 894.815. You will still be the sponsor but no longer the enrollee, and pursuant to § 894.811, your family members will only be eligible for FEDVIP dental coverage since you are a TEI-D who is not enrolled in FEDVIP and receives VA dental services and meets one of the conditions in § 894.309(a)(3)(iii). Upon cancellation of the enrollment, pursuant to § 894.811, a TEI family member can accept the responsibility to self-certify and enroll in a FEDVIP dental plan as a TEI certifying family member and cover other TEI family members.

(d) Cancellations under this section will become effective at the end of the pay period that you submit your request.
