(1)(a) Notwithstanding RCW 48.43.055 and 48.18.200, if good faith negotiation, as described in RCW 48.49.030 does not result in resolution of the dispute, and the carrier, out-of-network provider or out-of-network facility chooses to pursue further action to resolve the dispute, the carrier, out-of-network provider, or out-of-network facility shall initiate arbitration to determine a commercially reasonable payment amount. To initiate arbitration, the carrier, provider, or facility must provide written notification to the commissioner and the noninitiating party no later than ten calendar days following completion of the period of good faith negotiation under RCW 48.49.030. The notification to the noninitiating party must state the initiating party's final offer. No later than thirty calendar days following receipt of the notification, the noninitiating party must provide its final offer to the initiating party. The parties may reach an agreement on reimbursement during this time and before the arbitration proceeding.
(b) Multiple claims may be addressed in a single arbitration proceeding if the claims at issue:
(i) Involve identical carrier and provider or facility parties;
(ii) Involve claims with the same or related current procedural terminology codes relevant to a particular procedure; and
(iii) Occur within a period of two months of one another.
(2) Within seven calendar days of receipt of notification from the initiating party, the commissioner must provide the parties with a list of approved arbitrators or entities that provide arbitration. The arbitrators on the list must be trained by the American arbitration association or the American health lawyers association and should have experience in matters related to medical or health care services. The parties may agree on an arbitrator from the list provided by the commissioner. If the parties do not agree on an arbitrator, they must notify the commissioner who must provide them with the names of five arbitrators from the list. Each party may veto two of the five named arbitrators. If one arbitrator remains, that person is the chosen arbitrator. If more than one arbitrator remains, the commissioner must choose the arbitrator from the remaining arbitrators. The parties and the commissioner must complete this selection process within twenty calendar days of receipt of the original list from the commissioner.
(3)(a) Each party must make written submissions to the arbitrator in support of its position no later than thirty calendar days after the final selection of the arbitrator. The initiating party must include in its written submission the evidence and methodology for asserting that the amount proposed to be paid is or is not commercially reasonable. A party that fails to make timely written submissions under this section without good cause shown shall be considered to be in default and the arbitrator shall require the party in default to pay the final offer amount submitted by the party not in default and may require the party in default to pay expenses incurred to date in the course of arbitration, including the arbitrator's expenses and fees and the reasonable attorneys' fees of the party not in default. No later than thirty calendar days after the receipt of the parties' written submissions, the arbitrator must: Issue a written decision requiring payment of the final offer amount of either the initiating party or the noninitiating party; notify the parties of its decision; and provide the decision and the information described in RCW 48.49.050 regarding the decision to the commissioner.
(b) In reviewing the submissions of the parties and making a decision related to whether payment should be made at the final offer amount of the initiating party or the noninitiating party, the arbitrator must consider the following factors:
(i) The evidence and methodology submitted by the parties to assert that their final offer amount is reasonable; and
(ii) Patient characteristics and the circumstances and complexity of the case, including time and place of service and whether the service was delivered at a level I or level II trauma center or a rural facility, that are not already reflected in the provider's billing code for the service.
(c) The arbitrator may not require extrinsic evidence of authenticity for admitting data from the Washington state all-payer claims database data set developed under RCW 43.371.100 into evidence.
(d) The arbitrator may also consider other information that a party believes is relevant to the factors included in (b) of this subsection or other factors the arbitrator requests and information provided by the parties that is relevant to such request, including the Washington state all-payer claims database data set developed under RCW 43.371.100.
(4) Expenses incurred in the course of arbitration, including the arbitrator's expenses and fees, but not including attorneys' fees, must be divided equally among the parties to the arbitration. The enrollee is not liable for any of the costs of the arbitration and may not be required to participate in the arbitration proceeding as a witness or otherwise.
(5) Within ten business days of a party notifying the commissioner and the noninitiating party of intent to initiate arbitration, both parties shall agree to and execute a nondisclosure agreement. The nondisclosure agreement must not preclude the arbitrator from submitting the arbitrator's decision to the commissioner under subsection (3) of this section or impede the commissioner's duty to prepare the annual report under RCW 48.49.050.
(6) Chapter 7.04A RCW applies to arbitrations conducted under this section, but in the event of a conflict between this section and chapter 7.04A RCW, this section governs.
(7) This section applies to health care providers or facilities providing services to members of entities administering a self-funded group health plan and its plan members only if the entity has elected to participate in RCW 48.49.020 and 48.49.030 and this section as provided in RCW 48.49.130.
(8) An entity administering a self-funded group health plan that has elected to participate in this section pursuant to RCW 48.49.130 shall comply with the provisions of this section.
