Maximum Allowable Cost (MAC)

The PDCRx Maximum Allowable Cost (MAC) program sets the maximum per unit price for drugs, based on current market sources. All products are regularly reviewed and adjusted as necessary according to market conditions. PDCRx updates MAC lists at least every seven (7) days or as required by law. If a drug becomes scarce, the MAC may be suspended or the drug may be permanently removed from MAC lists at PDCRx’s discretion. The drug may be reinstated when PDCRx market sources confirm sufficient supply and distribution. The current sources used to determine MAC pricing include regional and national wholesalers, the National Average Drug Acquisition Cost (NADAC) published by CMS, Predictive Acquisition Cost (PAC) pricing, and Medi-Span. PDCRx reserves the right to change pricing sources at any time. The MAC list is available upon request and can be obtained by emailing price@pdcrx.com

Required documents:

  • The pharmacy must provide the PBM with all invoices or other records demonstrating its actual cost for the drug, medical product, or device, including the manufacturer's / distributor rebate received.

  • The appeal must be submitted at least within seven business days of its submission of the initial claim for reimbursement for the drug medical product, or device.

  • PDCRx will make a final determination of the appeal at least within seven business days of its submission of the initial claim for reimbursement for the drug, or medical product or device.
