What is Medicaid Drug Rebate Dispute Resolution?
The Medicaid Drug Rebate Dispute Resolution Program (DRP) is for states and/or manufacturers that are unable to mutually resolve Medicaid Drug Rebate Program (MDRP) disputes, in which they may request assistance from CMS’s Medicaid DRP Team.
In order for a dispute to be considered an official dispute, the state/manufacturer needs to have documented the disputed units on the official Reconciliation of State Invoice ROSI CMS Form-304 (PDF, 63.48 KB) or Prior Quarter Adjustment Statement PQAS CMS Form-304a (PDF, 87.15 KB), OMB Exp. 06.30.2023, which must be filled out completely, including the assignment of the appropriate dispute code(s), and any required documentation for the dispute code(s). Please note that an excel spreadsheet without appropriate context is not considered official documentation.
All disputes must be resolved on a unit basis only, and not on any other factor (e.g., monetary amounts, percentages, etc.). Additionally, non-payment of rebates are not disputes. CMS considers any unpaid rebates billed to manufacturers and not paid timely, without the required dispute documentation, as non-payment. Non-payment issues are addressed in Manufacturer Release No.105 (PDF, 186.05 KB), and State Release No.181 (PDF, 233.38 KB), and inquiries pertaining to non-payment should be sent to MDROperations@cms.hhs.gov (please include “Non-Payment” in the subject line).
Most states and manufacturers prefer to engage in the dispute resolution process; however, per Section V of the National Drug Rebate Agreement (NDRA), in accordance with 42 CFR §447.253(e), a state hearing option is available to both states and manufacturers when they have reached an impasse through the normal dispute resolution process, or when one of the parties is not being responsive to another’s efforts to engage in dispute resolution. Please note that either party may opt to use the state hearing process at any time; however, both parties must agree to engage in order to use the DRP process. The state hearing option is addressed in Manufacturer Release No.105 and State Release No.181.
