Washington Revised Code Title 48. Insurance § 48.37.130. Coordination with other state insurance regulators through the NAIC

(2)(a) If a market conduct examination or action performed by another state insurance regulator results in a finding that an insurer should modify a specific practice or procedure, the commissioner shall, in lieu of conducting a market conduct action or examination, accept verification that the insurer made a similar modification in this state, unless the commissioner determines that the other state does not have laws substantially similar to those of this state, or does not have a market conduct oversight system that is comparable to the market conduct oversight system set forth in this chapter.

(b) The commissioner's determination under (a) of this subsection is discretionary with the commissioner and is not subject to appeal.
