(1) The commissioner shall preserve in permanent form records of his or her proceedings, hearings, investigations, and examinations, and shall file such records in his or her office.
(2) The records of the commissioner and insurance filings in his or her office shall be open to public inspection, except as otherwise provided by this code.
(3) Except as provided in subsection (4) of this section, actuarial formulas, statistics, and assumptions submitted in support of a rate or form filing by an insurer, health care service contractor, or health maintenance organization or submitted to the commissioner upon his or her request shall be withheld from public inspection in order to preserve trade secrets or prevent unfair competition.
(4) For individual and small group health benefit plan rate filings submitted on or after July 1, 2011, subsection (3) of this section applies only to the numeric values of each small group rating factor used by a health carrier as authorized by RCW 48.21.045(3)(a), 48.44.023(3)(a), and 48.46.066(3)(a). Subsection (3) of this section may continue to apply for a period of one year from the date a new individual or small group product filing is submitted or until the next rate filing for the product, whichever occurs earlier, if the commissioner determines that the proposed rate filing is for a new product that is distinct and unique from any of the carrier's currently or previously offered health benefit plans. Carriers must make a written request for a product classification as a new product under this subsection and must receive subsequent written approval by the commissioner for this subsection to apply.
(5) Unless the commissioner has determined that a filing is for a new product pursuant to subsection (4) of this section, for all individual or small group health benefit rate filings submitted on or after July 1, 2011, the health carrier must submit part I rate increase summary and part II written explanation of the rate increase as set forth by the department of health and human services at the time of filing, and the commissioner must:
(a) Make each filing and the part I rate increase summary and part II written explanation of the rate increase available for public inspection on the tenth calendar day after the commissioner determines that the rate filing is complete and accepts the filing for review through the electronic rate and form filing system; and
(b) Prepare a standardized rate summary form, to explain his or her findings after the rate review process is completed. The commissioner's summary form must be included as part of the rate filing documentation and available to the public electronically.
