What is the Maximum Allowable Cost (MAC)?
A Maximum Allowable Cost (MAC) is applied to those drugs that have multiple suppliers and have been deemed interchangeable -that is, brand name drugs and their generic equivalents. For each interchangeable category, a maximum allowable cost per unit (e.g., tablet, capsule, milliliter, etc.) is determined by examining costs available from each manufacturer. The MAC is based on the lowest price available to the pharmacy. Pharmacists can bill the patient extra costs above the MAC price if the patient requests a particular brand and is willing to pay the difference. This extra cost is not counted towards a Pharmacare Program’s deductible or maximum annual copayment. MAC prices are reviewed each January and each July. Then a new Reimbursement List (PDF)is published and sent to all pharmacies in Nova Scotia. Updates may also be provided in the interim.
