In general. For each sales year, the IRS will compile a list of branded prescription drugs by NDC using the data submitted on Forms 8947 and in error reports submitted as part of the dispute resolution process (described in § 51.7) and, after applying appropriate due diligence, will provide this list to the Agencies. The Agencies will provide data to the IRS on branded prescription drug sales that occurred during the sales year by Program and NDC. The Agencies will provide data for use in preparing the preliminary fee calculation (described in §§ 51.5 and 51.6) and may revise or supplement that data following review of error reports submitted as part of the dispute resolution process. The calculation methodology for calculating the sales amounts for each Program, including any reasonable estimation techniques and assumptions that the Agencies expect to use, is described in this section.

Medicare Part D—(1) In general. CMS will determine branded prescription drug sales under Medicare Part D by aggregating the ingredient cost reported in the “Ingredient Cost Paid” field on the Prescription Drug Event (PDE) records at the NDC level, reduced by discounts, rebates, and other price concessions provided by the covered entity, for each sales year. CMS will only include PDE data that Part D sponsors have submitted by the PDE submission deadline (within 6 months after the end of the sales year) and that CMS has approved for inclusion in the Part D payment reconciliation.

Discounts, rebates, and other price concessions—(i) In general. For purposes of paragraph (b)(1) of this section, the term discounts, rebates, and other price concessions means:

Any direct and indirect remuneration (DIR) (within the meaning of paragraph (b)(2)(ii) of this section), which includes any DIR reported on the PDE records at the point of sale and any DIR reported on a Detailed DIR Report (within the meaning of a paragraph (b)(2)(iii) of this section); and

Any coverage gap discount amount (within the meaning of paragraph (b)(2)(iv) of this section).

Direct and indirect remuneration. For purposes of paragraph (b)(2)(i)(A) of this section, the term direct and indirect remuneration (DIR) has the same meaning as found in the definition of actually paid in 42 CFR 423.308.

Detailed DIR Report. For purposes of paragraph (b)(2)(i)(A) of this section, the term Detailed DIR Report means the report containing any DIR (within the meaning of paragraph (b)(2)(ii) of this section) that is collected yearly from Part D sponsors at the NDC level.

Coverage gap discount amount. For purposes of paragraph (b)(2)(i)(B) of this section, the term coverage gap discount amount means a 50-percent manufactured-paid discount on certain drugs under the Coverage Gap Discount Program described in section 1860D-14A of the Social Security Act.

Medicare Part B—(1) In general. CMS will determine branded prescription drug sales under Medicare Part B using the following two data sources:

CMS will use data reported by manufacturers pursuant to section 1847A(c) of the Social Security Act to calculate the annual weighted average sales price (ASP) for each Healthcare Common Procedure Coding System (HCPCS) code for the sales year.

CMS will use the Medicare Part B National Summary Data File located at http://www.cms.gov/NonIdentifiableDataFiles/03_PartBNationalSummaryDataFile.asp to obtain the number of allowed billing units per HCPCS code for claims incurred during the sales year.

Calculation—(i) In general. Using the data described in paragraph (c)(1) of this section, CMS will determine branded prescription drugs sales under Medicare Part B as described in paragraphs (c)(3), (4), and (5) of this section. CMS reports sales amounts per HCPCS billing code, not per NDC. Therefore, a covered entity's total Part B sales amounts for all NDCs in a given HCPCS billing code appears under only one NDC in each HCPCS billing code and the covered entity's remaining NDCs in the HCPCS billing code are listed with a sales amount of zero.

Example of a Part B sales report:

HCPCS code; single entity. For each HCPCS code consisting solely and exclusively of branded prescription drugs (as identified by their respective NDCs) manufactured by a single entity, CMS will multiply the annual weighted ASP by the total number of allowed billing units paid during the sales year to determine the total sales for all NDCs associated with the HCPCS code attributed to Medicare Part B.

HCPCS code; multiple manufacturers and/or multiple drugs—(i) Step one. For each HCPCS code consisting of a mixture of branded prescription drugs made by different manufacturers and/or a mixture of branded prescription and generic drugs, CMS will determine—

The annual weighted ASP for the HCPCS code;

The total number of allowed billing units paid by Medicare Part B for each HCPCS code during the sales year;

The names of the entities engaged in manufacturing each NDC assigned to the HCPCS code; and

Those entities (if any) identified in paragraph (c)(4)(i)(C) of this section that are manufacturing branded prescription drugs assigned to the HCPCS code.

Step two. Using the information from paragraph (c)(4)(i) of this section, CMS will then do the following:

Calculate the proportion of sales, expressed as a percentage, attributed to each NDC assigned to the HCPCS code by determining the percentage of total sales reported to CMS by each manufacturer of NDC(s) that are assigned to the HCPCS code. For example, if HCPCS code JXXXX contains three drugs with a total of $310,000 sales reported by manufacturers to CMS for the sales year, and $100,000 was reported for Drug A, $200,000 was reported for Drug B, and $10,000 was reported for Drug C, the proportion of sales attributed to each NDC will be 32.26 percent for Drug A, 64.52 percent for Drug B, and 3.22 percent for Drug C; and

For each NDC, multiply the product of the annual weighted ASP and the total allowed billing units paid by Medicare Part B for the HCPCS code by the proportion of sales calculated in paragraph (c)(4)(ii)(A) of this section to determine the sales reportable to the IRS (that is, percentage × (annual weighted ASP × allowed units) = total sales reported to IRS for the NDC). The sales for each manufacturer's NDCs assigned to a HCPCS code are summed and the total sales for each manufacturer's NDCs in a HCPCS code will be reported to the IRS.

HCPCS code; unable to establish a reliable proportion of sales. If CMS is unable to establish a reliable proportion of sales attributable to each NDC assigned to the HCPCS code using the method described in paragraph (c)(4)(ii)(A) of this section, CMS will use Medicare Part D utilization percentages in lieu of the proportion of sales determined under paragraph (c)(4)(ii)(A) of this section to perform the calculation described in paragraph (c)(4)(ii)(B) of this section.

Medicaid. (1) CMS will determine the branded prescription drug sales for Medicaid as the per-unit Average Manufacturer Price (AMP) less the Unit Rebate Amounts (URA) that CMS calculates based on manufacturer-reported pricing data multiplied by the number of units reported billed by states to manufacturers. This data will be based on the data reported to CMS for the sales year by covered entities and the states for drugs paid for by the states in the Medicaid Drug Rebate Program for the sales year. The data will include all branded prescription drug units for which the states bill rebates to covered entities under the Medicaid Drug Rebate Program. This program includes, but is not limited to, units paid for under various health care plans such as fee for service, managed care organizations, and drugs administered in a non-retail setting such as drugs administered in a physician's office, clinic, hospital or other setting. The Medicaid Drug Rebate Program's calculated branded prescription drug fee does not include state-only pharmaceutical program sales or rebates.

For any covered entity identified in the first five (or six) digits of an NDC during any of the four quarters of a sales year, CMS will use the following methodology to derive the sales figures that account for third-party payers, such as Medicare Part B:

Report total dollars per NDC for AMP minus URA multiplied by the units reported by a state or states.

Determine the percentage of the total amount reimbursed that is the Medicaid amount of that reimbursement. For example, if the total amount reimbursed is $100,000, and the Medicaid amount reimbursed is $20,000, then the percentage is 20 percent.

Multiply the percentage of the Medicaid amount of that reimbursement (in the example in paragraph (d)(2)(ii) of this section, 20 percent) by the dollar figure derived from paragraph (d)(2)(i) of this section (AMP minus URA multiplied by units) to get the new adjusted sales dollar totals.

Department of Veterans Affairs. VA will determine branded prescription drug sales to VA by providing, by NDC, the total amount paid (net of refunds and rebates, when they are associated with a specific NDC) for each branded prescription drug procured by VA for its beneficiaries during the sales year. For this purpose, a drug is procured on the invoice (billing) date. The basis of this information will be national procurement data reported during the sales year by VA's Pharmaceutical Prime Vendor to the VA Pharmacy Benefits Management Service and National Acquisition Center. VA sales data includes the Industrial Funding Fee and the Cost Recovery Fee because these amounts are part of the price VA pays to its Pharmaceutical Prime Vendor to procure a drug.

Department of Defense. DOD will determine branded prescription drug sales to DOD (for DOD programs other than the TRICARE retail pharmacy program) by providing, by Labeler Code, the manufacturer's name, the NDC, brand name, and the amount paid (net of rebates and or refunds) for each branded prescription drug procured by DOD (for DOD programs other than the TRICARE retail pharmacy program) during the sales year. For DOD programs other than the TRICARE retail pharmacy program, a drug is procured based upon the date it was ordered. DOD includes the Industrial Funding Fee and the Cost Recovery Fee in its drug sales data because these amounts are part of the price DOD pays to procure a drug.

TRICARE. DOD will determine branded prescription drug sales to DOD for the TRICARE retail pharmacy program by providing, by Labeler Code, the manufacturer's name, the NDC, brand name, and the amount paid (net of rebates or refunds) for each branded prescription drug procured by DOD through the TRICARE retail pharmacy program during the sales year. For the TRICARE retail pharmacy program, a drug is procured based upon the date it was dispensed. The amount paid is based on the submitted ingredient cost paid, aggregated by NDC, for eligible TRICARE retail pharmacy claims submitted during the program year, minus any refunds or rebates for the corresponding claims.
