Wash. Admin. Code § 284-30-630
If an insurer, including a health care service contractor or a health maintenance organization, intends to rely on an applicant's or enrollee's answers to health questions in an application to determine eligibility for coverage or the existence of a preexisting condition, such questions must be clear and precise. Simply asking whether the applicant has been under the care of a physician during the preceding year, for example, is not sufficient to require a "yes" answer where the applicant has been using medications that were prescribed prior to the start of the preceding year and the applicant has not seen a physician for more than a year.
