(3) Except as otherwise required by law, the authority shall direct the lead organization and the data vendor to maintain the confidentiality of claims or other data it collects for the database that include proprietary financial information, direct patient identifiers, indirect patient identifiers, or any combination thereof. Any entity that receives claims or other data must also maintain confidentiality and may only release such claims data or any part of the claims data if: (a) The claims data does not contain proprietary financial information, direct patient identifiers, indirect patient identifiers, or any combination thereof; and (b) The release is described and approved as part of the request in subsection (1) of this section. (4) The lead organization shall, in conjunction with the authority and the data vendor, create and implement a process to govern levels of access to and use of data from the database consistent with the following: (a) Claims or other data that include proprietary financial information, direct patient identifiers, indirect patient identifiers, unique identifiers, or any combination thereof may be released only to the extent such information is necessary to achieve the goals of this chapter set forth in RCW 43.371.020 (1) to researchers with approval of an institutional review board upon receipt of a signed data use and confidentiality agreement with the lead organization. A researcher or research organization that obtains claims data pursuant to this subsection must agree in writing not to disclose such data or parts of the data set to any other party, including affiliated entities, and must consent to the penalties associated with the inappropriate disclosures or uses of direct patient identifiers, indirect patient identifiers, or proprietary financial information adopted under RCW 43.371.070 (1).

Federal, state, tribal, and local government agencies that obtain claims data pursuant to this subsection are prohibited from using such data in the purchase or procurement of health benefits for their employees; (ii) Any entity when functioning as the lead organization under the terms of this chapter; and (iii) The Washington health benefit exchange established under chapter 43.71 RCW, upon receipt of a signed data use agreement with the authority and the lead organization as directed by rules adopted under this chapter.

(5) Reports utilizing data obtained under this section may not contain proprietary financial information, direct patient identifiers, indirect patient identifiers, or any combination thereof.

(6) Reports issued by the lead organization at the request of providers, facilities, employers, health plans, and other entities as approved by the lead organization may utilize proprietary financial information to calculate aggregate cost data for display in such reports. The authority shall approve by rule a format for the calculation and display of aggregate cost data consistent with this chapter that will prevent the disclosure or determination of proprietary financial information. In developing the rule, the authority shall solicit feedback from the stakeholders, including those listed in RCW 43.371.020 (5)(h), and must consider, at a minimum, data presented as proportions, ranges, averages, and medians, as well as the differences in types of data gathered and submitted by data suppliers.
