Wash. Admin. Code § 284-43-0252
Enrollees must have access to emergency services twenty-four hours per day, seven days per week. An issuer must make good faith attempts to contract with provider groups offering services within hospital emergency departments, if the hospital is included in its network. Such evidence of good faith efforts to contract will include documentation about the efforts to contract but not the substantive contract terms offered by either the issuer or the provider groups. If the issuer is unsuccessful in contracting with provider groups offering services within contracted hospital emergency departments, the issuer's provider directory must prominently note that while the hospital's emergency department is contracted, the providers within the department are not.
