CMS Proposing Major Changes to Medicaid Drug Rebate Program

Merle M. DeLancey, Jr. 

While you were at a Memorial Day barbeque, the Centers for Medicare & Medicaid Services (“CMS”) proposed major changes to the Medicaid Drug Rebate Program (“MDRP”). 2023-10934.pdf (federalregister.gov). Comments on the proposed rules are due July 25 but we recommend that you start working now.

The proposed rules are 187 pages and address drug misclassification and drug pricing and product data misreporting by pharmaceutical manufacturers. Also important for manufacturers, the rules propose program integrity and program administration changes, including limiting the time within which a manufacturer can initiate an audit of a State Medicaid Program’s drug utilization for purposes of Medicaid rebate obligations; clarifying requirements to accumulate or “stack” price concessions when a manufacturer determines best price; and providing for drug price verification and transparency through data collection.

Increased Transparency of Prescription Drug Costs

CMS is proposing to verify certain drug prices reported by manufacturers through an annual Medicaid Drug Price Verification Survey. According to CMS, verifying drug prices and publishing non-proprietary information about drug prices will increase public transparency for high-cost drugs allowing state Medicaid agencies to negotiate covered outpatient drug (“COD”) prices more effectively with manufacturers. This sounds eerily similar to the purposes behind a multitude of State drug pricing transparency programs.

The Medicaid Drug Rebate Program and Value-Based Purchasing

Merle M. DeLancey Jr.

On March 23, 2022, the Centers for Medicare and Medicaid Services (“CMS”) issued long-awaited guidance regarding how drug manufacturers are to report multiple best prices (“BPs”) to the Medicaid Drug Rebate Program (“MDRP”) under value-based purchasing (“VBP”) arrangements. See Manufacturer Release 116 (medicaid.gov/prescription-drugs/downloads/mfr-rel-116.pdf). CMS delayed issuing the guidance to allow states, payers, and manufacturers to administratively prepare for multiple BP reporting in connection with VBP arrangements. The regulatory amendments are effective July 1, 2022.

VBP Arrangements and Medicaid’s Best Price Rule

VBP arrangements consist of additional rebates or price concessions that states may be able to earn based on a drug’s clinical outcomes in Medicaid beneficiaries. CMS’ challenge was reconciling Medicaid’s long-standing BP reporting rule used to calculate manufacturer rebate payments to states with anticipated low prices available under VBP arrangements. Since 1991, the MDRP agreed to cover every drug a manufacturer sells regardless of price. In exchange for this unprecedented access, manufacturers agreed to pay rebates ensuring that Medicaid programs paid no more than the “best prices” paid by manufacturers’ commercial customers. Many argued that Medicaid’s BP rule prevented states from accessing innovative manufacturer programs involving cutting-edge therapies.
