20-1361. Insurance with other insurers; provision of service or expense incurred basis
A. There may be a provision as follows:
" Insurance with other insurers: If there be 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 prior to the occurrence or commencement of loss, the only liability under any expense incurred coverage of this policy shall be for such proportion of the loss as the amount which would otherwise have been payable hereunder plus the total of the like amounts under all such other valid coverages for the same loss of which this insurer had notice bears to the total like amounts under all valid coverages for such loss, and for the return of such portion of the premiums paid as shall 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 such other coverage shall be taken as the amount which the services rendered would have cost in the absence of such coverage."
B. If the policy provision set forth in subsection A of this section is included in a policy which also contains the policy provision set out in section 20-1362 there shall be added to the caption of the 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 any 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 such definition the term shall 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 policy provision with respect to any insured, any amount of benefit provided for the insured pursuant to any compulsory benefit statute, including any workers' compensation or employer's liability statute, whether provided by a governmental agency or otherwise shall in all cases be deemed to be " other valid coverage" of which the insurer has had notice. In applying the policy provision no third party liability coverage shall be included as " other valid coverage."
