Coordination of Benefits: If, with respect to a person covered under this policy, benefits for allowable expense incurred during a claim determination period under this policy, together with benefits for allowable expense during such period under all other valid coverage (without giving effect to this provision or to any "coordination of benefits provision" applying to such other valid coverage), exceed the total of such person's allowable expense during such period, this insurer shall be liable only for such proportionate amount of the benefits for allowable expense under this policy during such period as (a) the total allowable expense during such period bears to (b) the total amount of benefits payable during such period for such expense under this policy and all other valid coverage (without giving effect to this provision or to any "coordination of benefits provision" applying to such other valid coverage) less in both (a) and (b) any amount of benefits for allowable expense payable under other valid coverage which does not contain a "coordination of benefits provision." In no event shall this provision operate to increase the amount of benefits for allowable expense payable under this policy with respect to a person covered under this policy above the amount which would have been paid in the absence of this provision. This insurer may pay benefits to any insurer providing other valid coverage in the event of overpayment by such insurer. Any such payment shall discharge the liability of this insurer as fully as if the payment had been made directly to the insured or the assignee or beneficiary of the insured. If this insurer pays benefits to the insured or the assignee or beneficiary of the insured, in excess of the amount which would have been payable if the existence of other valid coverage had been disclosed, this insurer shall have a right of action against the insured or the assignee or beneficiary of the insured to recover the amount which would not have been paid had there been a disclosure of the existence of the other valid coverage. The amount of other valid coverage which is on a provision of service basis shall be computed as the amount the services rendered would have cost in the absence of such coverage.
For the purposes of this provision:
or, in lieu thereof:
The insurer shall include in this provision a definition of "other valid coverage" approved as to form by the Commissioner. Such term may include hospital, surgical, medical or major medical benefits provided by individual or family-type coverage, government programs or workers' compensation. Such term shall not include any automobile medical payments or third-party liability coverage. The insurer shall not include a subrogation clause in the policy. The insurer may require, as part of the proof of claim, the information necessary to administer this provision.
