Industrial health insurance is that form of individual health insurance for which the premium is payable weekly. No policy of industrial health insurance may be delivered or issued for delivery in this state unless it has printed thereon the words “industrial policy” or “weekly premium policy” or words of similar import. Each policy shall be subject to the provisions of this chapter except that:
(1) Any policy may contain a provision requiring proof of continuance of disability. If such provision is used, it shall be in the following words: “Affirmative proof of continuance of disability must be furnished at the expiration of each period for which a claim is filed.”
(2) The insurer may refuse to endorse the name of any proposed beneficiary who does not appear to the insurer to have an insurable interest in the life of the insured.
