Medicaid Claim Denials for No Drug Rebate Agreement on File

Posted September 1, 2017

As a reminder, National Drug Codes (NDCs) and all other required data elements must be billed on medical claims for Illinois Medicaid members. Additionally, a signed Medicaid Drug Rebate Agreement from each drug’s manufacturer, or pharmaceutical labeler, must be on file with the Centers for Medicare & Medicaid Services (CMS). This means that, even if the NDC is valid for the date of service and all other required elements are included, claims will be denied if there is no rebate agreement on file with CMS for a particular manufacturer. 

For more information, refer to the Medical Providers section of the Illinois Healthcare and Family Services (HFS) website at, where you will find the following resources:
