Abstract

This is an empty dataset for the purposes of managing permissions and access to the Medi-Span data on the PHS servers.

RxNorm provides normalized names for clinical drugs and links its names to many of the drug vocabularies commonly used in pharmacy management and drug interaction software, including those of First Databank, Micromedex, MediSpan, Gold Standard, and Multum. By providing links between these vocabularies, RxNorm can mediate messages between systems not using the same software and vocabulary.

RxNorm now includes the National Drug File - Reference Terminology (NDF-RT) from the Veterans Health Administration. NDF-RT is a terminology used to code clinical drug properties, including mechanism of action, physiologic effect, and therapeutic category.

This page provides background needed to take advantage of the capabilities of the MSIS Drug Utilization Datamart. This mart allows the user to develop high-level statistical tables covering Medicaid drug utilization for groups of drugs. This mart does not present data for each National Drug Code (NDC) but summarizes drug payments and claim counts using the MEDISPAN drug groupings developed by Wolters Kluwer Health, Inc.
