Wash. Rev. Code § 48.44.220
No health care service contractor shall deny coverage to any person solely on account of race, religion, national origin, or the presence of any disability. Nothing in this section shall be construed as limiting a health care service contractor's authority to deny or otherwise limit coverage to a person when the person because of a medical condition does not meet the essential eligibility requirements established by the health care service contractor for purposes of determining coverage for any person.
No health care service contractor shall refuse to provide reimbursement or indemnity to any person for covered health care services for reasons that the health care services were provided by a holder of a license under chapter 18.22 RCW.
