Under RCW 48.200.280, pharmacies have the right to appeal reimbursement for a drug subject to predetermined reimbursement costs for multisource generic drugs. Network pharmacies 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.
Washington State law—WAC 284-180-505—does not permit a pharmacy benefit manager to reject or refuse review of a MAC appeal on the basis of incomplete fields. The rule explicitly requires PBMs to accept any information a network pharmacy chooses to submit, including but not limited to:
- Documentation from the pharmacy’s wholesale ordering system
- Other proof of acquisition cost
- An attestation from the pharmacy, including a description of due diligence to procure the drug at the most favorable cost
The rule further mandates that the PBM must review and investigate all information submitted before issuing a decision. A blanket requirement that this information needs to be provided in order to initiate the appeal process is a direct violation of this statute.
Updated on January 1st, 2026, the RCW 48.200.280 (3) states:
(3) A pharmacy benefit manager must establish a process by which a network pharmacy, or its representative, may appeal its reimbursement for a drug. A network pharmacy may appeal a reimbursement amount paid by a pharmacy benefit manager for a drug if the reimbursement for the drug is less than the net amount that the network pharmacy paid to the supplier of the drug.
