Section 21.51.200 - Insurance with other insurers providing benefits for loss on a provision of service or expense incurred basis(a) There may be a provision as follows: "Insurance With Other Insurers: If there is other valid coverage, not with this insurer, providing benefits for the same loss on a provision of service basis or on an expense incurred basis and of which this insurer has not been given written notice before the occurrence or commencement of loss, the only liability under an expense incurred coverage of this policy shall be for the proportion of the loss that the amount that would otherwise have been payable hereunder plus the total of the like amounts under all the other valid coverages for the same loss of which this insurer had notice bears to the total like amounts under all valid coverages for the loss and for the return of the portion of the premiums paid that exceed the pro rata portion for the amount so determined. For the purpose of applying this provision when other coverage is on a provision of service basis, the "like amount' of the other coverage shall be taken as the amount which the services rendered would have cost in the absence of the coverage."
(b) If the policy provision in (a) of this section is included in a policy that also contains the policy provision set out in AS 21.51.210 there shall be added to the caption of the foregoing provision the phrase " - Expense Incurred Benefits." The insurer may, at its option, include in this provision a definition of "other valid coverage," approved as to form by the director, which definition shall be limited in subject matter to coverage provided by organizations subject to regulation by insurance law or by insurance authorities of this or any other state of the United States or a province of Canada, and by hospital or medical service organizations, and to any other coverage the inclusion of which may be approved by the director. In the absence of this definition the term may not include group insurance, automobile medical payments insurance, or coverage provided by hospital or medical service organizations or by union welfare plans or employer or employee benefit organizations. For the purpose of applying the foregoing policy provision with respect to an insured, an amount of benefit provided for the insured under a compulsory benefit statute (including a workers' compensation or employer's liability statute), whether provided by a governmental agency or otherwise, shall in all cases be considered to be "other valid coverage" of which the insurer has had notice. In applying the foregoing policy provision no third-party liability coverage shall be included as "other valid coverage."
