(1) The commissioner shall disapprove any such form of policy, application, rider, or endorsement, or withdraw any previous approval thereof, only:
(a) If it is in any respect in violation of or does not comply with this code or any applicable order or regulation of the commissioner issued pursuant to the code; or
(b) If it does not comply with any controlling filing theretofore made and approved; or
(c) If it contains or incorporates by reference any inconsistent, ambiguous or misleading clauses, or exceptions and conditions which unreasonably or deceptively affect the risk purported to be assumed in the general coverage of the contract; or
(d) If it has any title, heading, or other indication of its provisions which is misleading; or
(e) If purchase of insurance thereunder is being solicited by deceptive advertising.
(2) In addition to the grounds for disapproval of any such form as provided in subsection (1) of this section, the commissioner may disapprove any form of disability insurance policy if the benefits provided therein are unreasonable in relation to the premium charged. Rates, or any modification of rates effective on or after July 1, 2008, for individual health benefit plans may not be used until sixty days after they are filed with the commissioner. If the commissioner does not disapprove a rate filing within sixty days after the insurer has filed the documents required in RCW
48.20.025(2) and any rules adopted pursuant thereto, the filing shall be deemed approved.
