The Plan coverage defined in Section 6 shall provide for a choice of deductibles per individual as authorized by the Board. If 2 individual members of the same family household, who are both covered persons under the Plan, satisfy the same applicable deductibles, no other member of that family who is also a covered person under the Plan shall be required to meet any deductibles for the balance of that calendar year. The deductibles must be applied first to the authorized amount of covered expenses incurred by the covered person. A mandatory coinsurance requirement shall be imposed at the rate authorized by the Board in excess of the mandatory deductible, the coinsurance in the aggregate not to exceed such amounts as are authorized by the Board per annum. At its discretion the Board may, however, offer catastrophic coverages or other policies that provide for larger deductibles with or without coinsurance requirements. The deductibles and coinsurance factors may be adjusted annually according to the Medical Component of the Consumer Price Index.
During the pendency of any action or claim that is brought by or on behalf of a covered person against a third party or its insurer, any benefits that would otherwise be payable except for the provisions of this paragraph (3) shall be paid if payment by or for the third party has not yet been made and the covered person or, if incapable, that person's legal representative agrees in writing to pay back promptly the benefits paid as a result of the sickness or injury to the extent of any future payments made by or for the third party for the sickness or injury. This agreement is to apply whether or not liability for the payments is established or admitted by the third party or whether those payments are itemized.
Any amounts due the plan to repay benefits may be deducted from other benefits payable by the Plan after payments by or for the third party are made.
