(3) A pharmacy benefit manager must establish a process by which a network pharmacy may appeal its reimbursement for a drug subject to predetermined reimbursement costs for multisource generic drugs. A network pharmacy may appeal a predetermined reimbursement cost for a multisource generic drug if the reimbursement for the drug is less than the net amount that the network pharmacy paid to the supplier of the drug. An appeal requested under this section must be completed within thirty calendar days of the pharmacy submitting the appeal. If after thirty days the network pharmacy has not received the decision on the appeal from the pharmacy benefit manager, then the appeal is considered denied.

The pharmacy benefit manager shall uphold the appeal of a pharmacy with fewer than fifteen retail outlets, within the state of Washington, under its corporate umbrella if the pharmacy or pharmacist can demonstrate that it is unable to purchase a therapeutically equivalent interchangeable product from a supplier doing business in Washington at the pharmacy benefit manager's list price.

(5)(a) If an appeal is upheld under this section, the pharmacy benefit manager shall make a reasonable adjustment on a date no later than one day after the date of determination.

(b) If the request for an adjustment has come from a critical access pharmacy, as defined by the state health care authority by rule for purposes related to the prescription drug purchasing consortium established under RCW 70.14.060, the adjustment approved under (a) of this subsection shall apply only to critical access pharmacies.

(6) Beginning July 1, 2017, if a network pharmacy appeal to the pharmacy benefit manager is denied, or if the network pharmacy is unsatisfied with the outcome of the appeal, the pharmacy or pharmacist may dispute the decision and request review by the commissioner within thirty calendar days of receiving the decision.

(a) All relevant information from the parties may be presented to the commissioner, and the commissioner may enter an order directing the pharmacy benefit manager to make an adjustment to the disputed claim, deny the pharmacy appeal, or take other actions deemed fair and equitable.
