State Drug Utilization Data FAQs

No. In accordance with federal laws, State Drug Utilization Data (SDUD) that has been suppressed is not available for public consumption.  As CMS is obligated by the Federal Privacy Act, 5 U.S.C. Section 552a and the HIPAA Privacy Rule, 45 C.F.R Parts 160 and 164, to protect the privacy of individual beneficiaries and other persons, all direct identifiers have been removed and data that are less than eleven (11) counts are suppressed. A checkmark in the "Suppression Used" column notes suppressed data. CMS applies counter or secondary suppression in cases where only one prescription is suppressed for primary reasons, (e.g., one prescription in a state). Also, if one sub-group (e.g., number of prescriptions) is suppressed, then the other sub-group is suppressed.

In general, all states cover all drugs (that meet the statutory definition of a covered outpatient drug per section 1927 of the Social Security Act (the Act)) of every manufacturer that participates in the Medicaid Drug Rebate Program (MDRP). However, section 1927(d)(2) of the Act does list several categories of drugs that states may, at their option, exclude or restrict from coverage under the MDRP. These categories include things like non-prescription drugs, drugs used for cosmetic purposes, etc. Therefore, while most states cover the same subset of drugs, there is some flexibility afforded to the states which can result in coverage differences from one state to the next.

Each quarter, a drug product listing is available from the  approximately 45 days after the close of the quarter. This information contains the active drugs that have been reported for inclusion in the Medicaid Drug Rebate Program (MDRP) by participating drug manufacturers as of the most recent rebate reporting period.

The drug utilization data that states report to CMS is reported at the NDC level. Therefore, for purposes of the Medicaid Drug Rebate Program (MDRP), crosswalk from HCPCS code to NDC should have already occurred prior to the states reporting their drug utilization data to CMS. Medicare Part B does post a HCPCS to NDC crosswalk ; however, please note that the subset of drugs covered under Part B is much smaller than  the drugs covered under the MDRP. Therefore, you may not find this crosswalk to be all-inclusive of every product covered under the MDRP.

For current versions of MDRP File Formats/Data Definitions, please refer to: https://www.medicaid.gov/medicaid/prescription-drugs/medicaid-drug-rebate-program/medicaid-drug-rebate-program-mdrp-file-formats-data-definitions-and-medicaid-drug-programs-mdp-email-communications/index.html

Per the state drug utilization data table, the "Dataset Views" dropdown selections available are:

• State: State-specific data at the NDC-11 level, for a quarter/year.
• Full Dataset (States + National Totals): A compilation of all the individual state utilization data (50 states plus Washington D.C.) and the National Totals at the NDC-11 level, for a selected year.
• All States: Includes data for all states but does not include the National Totals
• National Totals: Data are aggregated for all 50 states and Washington, D.C. at the NDC-11 level, for a quarter/year.

Since all of the states are combined in the National Totals, the state abbreviation will show on the "Annual State Detail" with a state abbreviation of "XX".

Users can also generate his or her own views of the dataset on data.medicaid.gov.

A Non-Medicaid Reimbursed amount is any amount paid on a claim by parties other than Medicaid (e.g., other federal coverage, co-pay, private insurance). If a state receives Federal Financial Participation (FFP) for any part of a claim for a Covered Outpatient Drug (COD), that portion of the claim is included in the Medicaid Reimbursed amount. If a state does not receive FFP for any part of a rebate-eligible claim, then the amount of the claim is included in the Non-Medicaid Reimbursed amount.

States are required to submit their utilization data to CMS within 60 days of the end of the rebate period.

You are likely running into a limitation of the program you are trying to use to analyze the data. Microsoft Excel allows 1,048,576 rows of data and many of our datasets exceed this limit.

We recommend users not use Excel for large datasets but instead use another application that can work with datasets of large size (e.g. Microsoft Access).

As CMS is obligated by the Federal Privacy Act, 5 U.S.C. Section 552a and the HIPAA Privacy Rule, 45 C.F.R Parts 160 and 164, to protect the privacy of individual beneficiaries and other persons, all direct identifiers have been removed and data that are less than eleven (11) counts are suppressed. An asterisk (*) notes suppressed data. CMS applies counter or secondary suppression in cases where only one prescription is suppressed for primary reasons, e.g. one prescription in a state. Also, if one sub-group (e.g. number of prescription) is suppressed, then the other sub-group is suppressed.
