Washington Revised Code Title 48. Insurance § 48.49.070. Requirement to provide certain information on website or upon consumer request--Requirement to provide carriers with nonemployed provider lists

(2) Posting or otherwise providing the information required in this section does not relieve a hospital, ambulatory surgical facility, behavioral health emergency services provider, or ground ambulance services organization of its obligation to comply with the provisions of this chapter.

(3) Not less than 30 days prior to executing a contract with a carrier, a hospital or ambulatory surgical facility must provide the carrier with a list of the nonemployed providers or provider groups contracted to provide emergency medicine, anesthesiology, pathology, radiology, neonatology, surgery, hospitalist, intensivist, and diagnostic services, including radiology and laboratory services at the hospital or ambulatory surgical facility. The hospital or ambulatory surgical facility must notify the carrier within thirty days of a removal from or addition to the nonemployed provider list. A hospital or ambulatory surgical facility also must provide an updated list of these providers within 14 calendar days of a request for an updated list by a carrier.
