If a payor that contracts with an ambulatory surgical facility licensed under chapter 70.230 RCW requires successful completion of a survey as part of the contract, the ambulatory surgical facility is deemed to have met survey requirements if it has successfully completed a survey performed pursuant to medicare certification or by an accrediting organization that has been determined by the secretary of the department of health to have substantially equivalent survey standards to those of the centers for medicare and medicaid services. The payor may not impose additional survey requirements on the ambulatory surgical facility.
