Prescription Drug Prices: 10 Definitions All Payers $hould Know
Acquisition Cost is defined as the invoice price to the pharmacy for a prescription drug dispensed to a patient, minus the amount of all discounts and other cost reductions attributable to such dispensed drug. Average Manufacturer Price (AMP) is the average price paid to the manufacturer for the drug in the United States by wholesalers for drugs distributed to retail community pharmacies and by retail community pharmacies that purchase drugs directly from the manufacturer. The health reform law excludes payments and rebates or discounts provided to certain providers and payers from the calculation of AMP. In March of this year, the Affordable Care Act (ACA) again amended the legal definition of average manufacturer price (AMP). AMP uniquely serves to determine both a multiple source drug’s reimbursement amount and the rebate amounts for single source, innovator single source, and multiple source drugs within the Medicaid program. No other pricing metric serves this dual function. Average Sales Price (ASP) - In 2005, Medicare began to pay for most drugs using an entirely new methodology based on ASP rather than AWP. Unlike AWP and WAC, there is a specific method to calculate ASP set forth in the MMA and the Act. Section 1847A(c) of the Act, as amended by the MMA, defines ASP as a manufacturer’s unit sales of a drug to all purchasers in the United States in a calendar quarter divided by the total number of drug units sold by the manufacturer in that same quarter. The ASP is net of any price concessions such as volume, prompt pay, and cash discounts; free goods contingent on purchase requirements; chargebacks; and rebates other than those obtained through the Medicaid drug rebate program. Certain sales are exempt from the calculation of ASP, including sales at a nominal charge. Average Wholesale Price (AWP) is not based on actual transactional, marketplace price data. Despite its name and its sometime use as a price index, the published AWP is not an average of actual wholesale prices. It is not intended to represent, and cannot be assumed to reflect, actual transaction prices. A wholesaler or other direct purchaser from a pharmaceutical manufacturer may agree to sell its products to one or more of its customers at prices that on their face are effectively lower than the published AWP. AWP information does not reflect any such lower pricing that may be made available in actual purchase transactions through a variety of methods, including, but not limited to, purchase, prompt-pay or other discounts, volume or other rebates or credits, or a variety of other price reduction arrangements. Direct Price (DP) is the price directly reported to AWP publishers by a manufacturer as the list price at which non-wholesalers and healthcare providers may purchase drug products from that manufacturer. These publishers generally do not receive a reported DP for drugs that are sold by a manufacturer exclusively through wholesalers, although in some cases both a DP and a WAC may be provided at the manufacturer’s discretion. DP does not represent an actual sales price…
