Title 42 - Public Health
(a) Calculation of manufacturer's average sales price. (1) The manufacturer's average sales price for a quarter for a drug or biological represented by a particular 11-digit National Drug Code must be calculated as the manufacturer's sales to all purchasers in the United States for that particular 11-digit National Drug Code (after deducting the types of items and transactions listed in paragraph (a)(2) of this section and excluding sales referenced in paragraph (a)(4) of this section) divided by the total number of units sold by the manufacturer in that quarter (after excluding units associated with sales referenced in paragraph (a)(4) of this section). (2) In calculating the manufacturer's average sales price, a manufacturer must deduct the following types of transactions and items: (i) Volume discounts. (ii) Prompt pay discounts. (iii) Cash discounts. (iv) Free goods that are contingent on any purchase requirement. (v) Chargebacks and rebates (other than rebates under the Medicaid drug rebate program). (3) To the extent that data on price concessions, as described in paragraph (a)(2) of this section, are available on a lagged basis, the manufacturer must estimate this amount in accordance with the methodology described in paragraphs (a)(3)(i) through (a)(3)(iv) of this section. (i) For each such National Drug Code, the manufacturer calculates a percentage equal to the sum of the price concessions for the most recent 12-month period available associated with sales subject to the average sales price reporting requirement divided by the total in dollars for the sales subject to the average sales price reporting requirement for the same 12-month period. (ii) The manufacturer then multiplies the percentage described in paragraph (a)(3)(i) of this section by the total in dollars for the sales subject to the average sales price reporting requirement for the quarter being submitted. (The manufacturer must carry a sufficient number of decimal places in the calculation of the price concessions percentage in order to round accurately the net total sales amount for the quarter to the nearest whole dollar.) The result of this multiplication is then subtracted from the total in dollars for the sales subject to the average sales price reporting requirement for the quarter being submitted. (iii) The manufacturer then uses the result of the calculation described in paragraph (a)(3)(ii) of this section as the numerator and the number of units sold in the quarter as the denominator to calculate the manufacturer's average sales price for the National Drug Code in the quarter being submitted. (iv) Example. The total lagged price concessions (discounts, rebates, etc.) over the most recent 12-month period available associated with direct sales for National Drug Code 12345–6789–01 subject to the ASP reporting requirement equal $200,000. The total in dollars for the sales subject to the average sales price reporting requirement for the same period equals $600,000. The lagged price concessions percentage for this period equals 200,000/600,000 = .33333. The total in dollars for the direct sales subject to the average sales price reporting requirement for the quarter being reported equals $50,000 for 10,000 units sold. Assuming no non-lagged price concessions apply, the manufacturer's average sales price calculation for this National Drug Code for this quarter is: $50,000−(0.33333 × $50,000) = $33,334 (net total sales amount); $33,334/10,000 = $3.33 (average sales price). (4) In calculating the manufacturer's average sales price, a manufacturer must exclude sales that are exempt from the Medicaid best price calculation under sections 1927(c)(1)(C)(i) and 1927(c)(1)(C)(ii)(III) of the Act. (5) The manufacturer's average sales price must be calculated by the manufacturer every calendar quarter and submitted to CMS within 30 days of the close of the quarter. The first quarter submission must be submitted by April 30, 2004. Subsequent reports are due not later than 30 days after the last day of each calendar quarter. (6) Each report must be certified by one of the following: (i) The manufacturer's Chief Executive Officer (CEO). (ii) The manufacturer's Chief Financial Officer (CFO). (iii) An individual who has delegated authority to sign for, and who reports directly to, the manufacturer's CEO or CFO.
