Section 4.03 - Dual and Split Enrollment(a) No person may be enrolled simultaneously in any benefit plan offered or sponsored by the Fund as both an employee-beneficiary and a dependent-beneficiary, nor may children be enrolled by more than one employee-beneficiary. The Fund shall cancel such dual coverage enrollments.(b) Employee-beneficiaries who are married or in a domestic partnership and have an enrolled dependent-beneficiary are limited to employer contributions for a family plan. If the employee-beneficiaries elect to enroll in a self and two party or self and family coverage, the employee-beneficiaries shall be responsible for health benefit premium in excess of the maximum employer contribution for a family plan. The additional premium must be paid directly to the Fund within the month for which coverage was provided. Failure to make a timely payment in full shall be treated as a shortage as defined in Rule 4.10.
