Except as provided in § 58-17-13, no policy of health insurance delivered or issued for delivery to any person in this state shall contain provisions respecting the matters set forth in §§ 58-17-32 to 58-17-40, inclusive, unless such provisions are in the words in which the same appear in the applicable section, except that the insurer may, at its option, use in lieu of any such provision a corresponding provision of different wording approved by the director which is not less favorable in any respect to the insured or the beneficiary. Any such provision contained in the policy shall be preceded individually by the applicable caption or, at the option of the insurer, by such appropriate individual or group captions or subcaptions as the director may approve.
