Filing, approval, and disapproval of forms.

(1) A basic insurance policy or application form for which written application is required and is to be a part of the policy or contract or printed rider or endorsement form may not be issued by a self-insurance fund unless the form has been filed with and approved by the office.

(2) Every such filing shall be made not less than 30 days in advance of any such use or delivery. At the expiration of such 30 days, the form so filed shall be deemed approved unless prior thereto it has been affirmatively approved or disapproved by order of the office. The office may extend by not more than an additional 15 days the period within which it may so affirmatively approve or disapprove any such form, by giving notice of such extension before expiration of the initial 30-day period. At the expiration of any such period as so extended, and in the absence of such prior affirmative approval or disapproval, any such form must be deemed approved.

(3) The office shall disapprove any form or withdraw any previous approval thereof only, if the form:

(a) Is in any respect in violation of, or does not comply with, this code.

(b) Contains or incorporates by reference, when such incorporation is otherwise permissible, any inconsistent, ambiguous, or misleading clauses, or any exceptions and conditions which deceptively affect the risk purported to be assumed in the general coverage of the contract.

(c) Has any title, heading, or other indication of its provisions which is misleading.

(d) Is printed or otherwise reproduced in such manner as to render any material provision of such form substantially illegible.
