1. There may be a provision as follows:

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:

(1) “Allowable expense” means 100 percent of any necessary, reasonable and customary item of expense which is covered, in whole or in part, as a hospital, surgical, medical or major medical expense under this policy or under any other valid coverage.

(2) “Claim determination period” with respect to any covered person means the initial period of ..... (insert period of not less than 30 days) and each successive period of a like number of days, during which allowable expense covered under this policy is incurred on account of such person. The first such period begins on the date when the first such expense is incurred, and successive periods shall begin when such expense is incurred after expiration of a prior period.

or, in lieu thereof:

(2) “Claim determination period” with respect to any covered person means each ..... (insert calendar or policy period of not less than a month) during which allowable expense covered under this policy is incurred on account of such person.

(3) “Coordination of benefits provision” means this provision and any other provision which may reduce an insurer’s liability because of the existence of benefits under other valid coverage.

2. The foregoing policy provisions may be inserted in all policies providing hospital, surgical, medical or major medical benefits for which the application includes a question as to other coverages subject to this provision. If the policy provision stated in subsection 1 is included in a policy which also contains the policy provision stated in NRS 689A.240, there shall be added to the caption of the provision stated in subsection 1 of the phrase “expense-incurred benefits.” The insurer may make this provision applicable to either or both:

(a) Other valid coverage with other insurers; and

(b) Other valid coverage with the same insurer.

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.

3. If by application of any of the foregoing provisions the insurer effects a material reduction of benefits otherwise payable under the policy, the insurer shall refund to the insured any premium unearned on the policy by reason of such reduction of coverage during the policy year current and that next preceding at the time the loss commenced, subject to the insurer’s right to provide in the policy that no such reduction of benefits or refund will be made unless the unearned premium to be so refunded amounts to $5 or such larger sum as the insurer may so specify.
