Requirements—Use of tamper-resistant prescription pads.

(1) The medicaid agency requires providers to use tamper-resistant prescription pads or paper for written outpatient prescriptions, including over-the-counter drugs, for Washington apple health clients.
(2) This requirement applies to all outpatient prescription drugs, including:
(a) Prescriptions when medicaid is primary or secondary payer (including medicare Part D prescriptions).
(b) Signed hardcopy prescriptions given to a client, whether handwritten or computer-generated.
(3) This requirement does not apply to:
(a) Prescriptions paid for by Washington's healthy options (HO) program or other agency-contracted managed care organizations.
(b) Prescription drugs that are part of the per diem or bundled rate and not reimbursed separately in designated institutional or clinical settings, such as a nursing facility, ICF/MR, dental office, hospice, or radiology. For example, a morphine prescription used to control a hospice client's cancer pain is covered under the hospice per diem rate and therefore the tamper-resistant prescription requirement is not required.
(c) Telephone, fax, or electronic prescriptions.

How the medicaid agency determines when a drug requires authorization.

(1) The medicaid agency's pharmacists or medical consultants periodically evaluate covered drugs, covered indications, or new dosages approved by the Food and Drug Administration (FDA) to determine the drug authorization requirement.
(a) The clinical team evaluates and grades available information for each drug or drug class based on quality evidence contained in compendia of drug information and peer-reviewed medical literature. The information evaluated includes, but is not limited to:
(i) Evidence for efficacy and safety;
(ii) Cost comparisons of drugs with similar existing drugs;
(iii) Potential for clinical misuse;
(iv) Potential for client misuse or abuse;
(v) Drugs with a narrow therapeutic index;
(vi) Other safety concerns; or
(vii) Product cost and outcome data demonstrating the cost effectiveness of the drug, device, or drug-related supply.
(b) In performing this evaluation the clinical team may consult with other agency clinical staff, financial experts, and program managers. The agency clinical team may also consult with an evidence-based practice center (EPC), evidence-based drug reviews, other purchasers, the drug use review (DUR) board, and medical experts in this evaluation.
(c) Based on the clinical team's evaluation, the agency may determine that the drug, device, or drug-related supply:
(i) Requires authorization;
(ii) Requires authorization to exceed agency-established limitations; or
(iii) Does not require authorization.
(2) The agency periodically reviews existing drugs, devices, or drug-related supplies and reassigns authorization requirements as necessary according to the same provisions as outlined above for new drugs, devices, or pharmaceutical supplies.
(3) For any drug, device, or drug-related supply with limitations or requiring authorization, the agency may elect to apply automated authorization criteria according to WAC 182-530-3200.

Billing requirements—Point-of-sale (POS) system/prospective drug use review (Pro-DUR).

(1) Pharmacy claims for drugs and other products listed in the medicaid agency's drug file and billed to the agency by national drug code (NDC) are adjudicated by the agency's point-of-sale (POS) system. Claims must be submitted for payment using the billing unit standard identified in WAC 182-530-5000.
(2) All pharmacy drug claims processed through the POS system undergo a system-facilitated prospective drug use review (Pro-DUR) screening as a complement to the Pro-DUR screening required of pharmacists.
(3) If the POS system identifies a potential drug therapy problem during Pro-DUR screening, a message will alert the pharmacy provider indicating the type of potential problem. The alerts regarding possible drug therapy problems include, but are not limited to:
(a) Therapeutic duplication;
(b) Duration of therapy exceeds the recommended maximum period;
(c) Drug-to-drug interaction;
(d) Drug disease precaution;
(e) High dose;

(c) Input from state-employed or contracted actuaries; and
(d) Dispensing fees paid by other third-party payers including, but not limited to, health care plans and other states' medicaid agencies.
(4) The agency uses a tiered dispensing fee system which pays higher volume pharmacies at a lower fee and lower volume pharmacies at a higher fee.
(5) The agency uses total annual prescription volume (both medicaid and nonmedicaid) reported to the agency to determine each pharmacy's dispensing fee tier. The following tier levels are effective for dates of service on and after July 1, 2023:
(a) A pharmacy which fills 70,000 or more prescriptions annually is a high-volume pharmacy. The agency considers hospital-based pharmacies that serve both inpatient and outpatient clients as high-volume pharmacies.
(b) A pharmacy which fills between 30,000 and 69,999 prescriptions annually is a mid-volume pharmacy.
(c) A pharmacy which fills less than 30,000 prescriptions annually is a low-volume pharmacy.
(6) The agency determines a pharmacy's annual total prescription volume as follows:
(a) The agency sends out a prescription volume survey form to pharmacy providers during the first quarter of the calendar year;
(b) Pharmacies return completed prescription volume surveys to the agency each year. Pharmacy providers not responding to the survey by the specified date are assigned to the high volume category;
(c) Pharmacies must include all prescriptions dispensed from the same physical location in the pharmacy's total prescription count;
(d) The agency considers prescriptions dispensed to nursing facility clients as outpatient prescriptions; and
(e) Assignment to a new dispensing fee tier is effective on the first of the month, following the date specified by the agency.
(7) A pharmacy may request a change in dispensing fee tier during the interval between the annual prescription volume surveys. The pharmacy must substantiate such a request with documentation showing that the pharmacy's most recent six-month dispensing data, annualized, would qualify the pharmacy for the new tier. If the agency receives the documentation by the twentieth of the month, assignment to a new dispensing fee tier is effective on the first of the following month.
(8) The agency grants general dispensing fee rate increases only when authorized by the legislature. Amounts authorized for dispensing fee increases may be distributed nonuniformly (e.g., tiered dispensing fee based upon volume).
(9) The agency may pay true unit dose pharmacies at a different rate for unit dose dispensing.

Reimbursement—Federal upper limit (FUL).

(1) The medicaid agency adopts the federal upper limit (FUL) set by the Centers for Medicare and Medicaid Services (CMS).
(2) The agency's maximum payment for multiple-source drugs for which CMS has set FULs will not exceed, in the aggregate, the prescribed upper limits plus the dispensing fees set by the agency.
(3) Except as provided in WAC 182-530-7300, the agency uses the FUL as the agency's reimbursement rate for the drug when the FUL price is the lowest of the rates calculated under the methods listed in WAC 182-530-7000.

ReimbursementMaximum allowable cost (MAC).

(1) The medicaid agency establishes a maximum allowable cost (MAC) for a multiple-source drug which is available from at least two manufacturers/labelers.
(2) The agency determines the MAC for a multiple-source drug:
(a) When specific regional and local drug acquisition cost data is available, the agency:
(i) Identifies what products are available from wholesalers for each drug being considered for MAC pricing;
(ii) Determines pharmacy providers' approximate acquisition costs for these products; and
(iii) Establishes the MAC at a level which gives pharmacists access to at least one product from a manufacturer with a qualified rebate agreement (see WAC 182-530-7500(4)).
(b) When specific regional and local drug acquisition cost data is not available, the agency may estimate acquisition cost based on national pricing sources.
(3) The MAC established for a multiple-source drug does not apply if the written prescription identifies that a specific brand is medically necessary for a particular client. In such cases, the actual acquisition cost (AAC) for the particular brand applies, provided authorization is obtained from the agency as specified under WAC 182-530-3000.
(4) Except as provided in subsection (3) of this section, the agency reimburses providers for a multiple-source drug at the lowest of the rates calculated under the methods listed in WAC 182-530-7000.
(5) The MAC established for a multiple-source drug may vary by package size, including those identified as unit dose national drug codes (NDCs) by the manufacturer or manufacturers of the drug.

ReimbursementAutomated maximum allowable cost (AMAC).

(1) The medicaid agency uses the automated maximum allowable cost (AMAC) pricing methodology for multiple-source drugs that are:
(a) Not on the published maximum allowable cost (MAC); and
(b) Produced by two or more manufacturers/labelers, at least one of which must have a current, signed federal drug rebate agreement.
(2) The agency establishes AMAC as a specified percentage of the published national average drug acquisition cost (NADAC) or other nationally accepted pricing source in order to estimate acquisition cost.
(3) The agency sets the percentage discount from NADAC for AMAC reimbursement using any of the information sources identified in WAC 182-530-8000.
(4) The agency may set AMAC reimbursement at different percentage discounts from NADAC for different multiple source drugs. The agency considers the same factors as those in WAC 182-530-8000.
(5) AMAC reimbursement for all products with the same ingredient, form and strength is at the AMAC determined for the second lowest priced product, or the AMAC of the lowest priced drug from a manufacturer with a current, signed federal rebate agreement.
(6) The agency recalculates the AMAC each time the drug file contractor provides a pricing update.
(7) Except as provided in WAC 182-530-7300, the agency reimburses at the lowest of the rates calculated under the methods listed in WAC 182-530-7000.
