​Average Manufacturer Pricing Submission Guidelines

Return to Drug Rebate Home Page​

Guidelines for quarterly submission of Average Manufacturer Pricing (AMP) to the State of California Department of Health Care Services (Department) for National Drug Codes (NDCs) subject to contracted supplemental rebates are outlined in the documents available upon request at DrugRebateBranch@dhcs.ca.gov . There is also a sample spreadsheet that contains the correct format the AMP data must be in for submission to the Department's fiscal intermediary, DXC​.

The Department's due date is the same as the CMS due date, which is 30 days after the end of each quarter. 

The Department must have the AMP data for the supplemental Medi-Cal contracts at the earliest possible date in order to prepare an accurate invoice. AMP data received at DXC after the due date will result in incomplete invoices. Please remember that incorrect or improperly formatted data will be returned for corrections. Continued incorrectly formatted and/or late AMP data submissions will adversely affect how the Department reviews future drug contract offers or renewals from your company. These delays in submission may also result in substantial financial penalties.

Please pay particular attention to the comments at the top of each column heading of the spreadsheet. The goal of DXC is to achieve a 100% accuracy rate upon loading of AMP data onto their system as it requires this level of detail.

AMP data should be sent via electronic format and/or paper with a cover letter identifying the labeler name, labeler number, address, telephone number and an email address for the company contact person. The Department also recommends using certified overnight mail with a return receipt.

However, it is recommended that AMP data be submitted electronically to the following e​mail address: Medi-CalDrugRebate@dxc.com​. 

Please direct AMP data to the contact shown below:​

Any questions regarding AMP submission can be directed to DXC at (916) 375-3443.

If manufacturers have any questions regarding State of California, Medi-Cal Supplemental Contract(s) with the Department of Health Care Services, please contact the Government Affairs representative with your company. The Government Affairs representative can contact the Department if there are further questions.
