NCI Thesaurus Code Lists The Federal Medication Terminologies (FMT) is a set of controlled terminologies and code sets from component vocabulary systems developed and maintained by the Food and Drug Administration, National Library of Medicine, Veterans Health Administration, National Cancer Institute and Agency for Healthcare Research and Quality. The National Cancer Institute component terminology within the FMT is the NCI Thesaurus (NCIt) and is pointed to within the External Code List publications for obtaining values for applicable data elements. NCI Thesaurus Subsets. NCI has provided a link to subset files specific to the NCPDP standards usage. The subsets were created by NCI terminologists to provide smaller sets of concepts for ease of use. The files can be downloaded from here or here. Subset files include (but are not limited to): Drug StrengthForm, StrengthUnitofMeasure, QuantityUnitOfMeasure, DEASchedule, MeasurementUnitCode, and DoseUnitOfMeasure Terminology. Important: Please see the SCRIPT Implementation Recommendations document (http://www.ncpdp.org/Resources/ePrescribing under NCPDP Resources), section "Quantity Qualifier Recommendations for Electronically Created Prescriptions" for important guidance on the use of the NCPDP QuantityUnitOfMeasure Terminology concepts, and the expected implementation. Note: The NCI database is reconciled the last Monday of every month; this is the database from which a version is generated to correspond to the files posted on the ftp site. The files will be posted during the following two weeks. It is important to note that the NCPDP subsets may change slightly on occasion as a definition might be tweaked or a new synonym created. However, the substance of the NCPDP subsets will not change unless a concept is brought forward to NCI that may impact NCPDP subsets. NCI will notify NCPDP if an addition or change is requested. When a new version of the subsets are created, the previous version of the subsets will go into the Archive and the new dated release will be listed on the ftp site (http://evs.nci.nih.gov/ftp1/NCPDP/). NCI will also include a file that will show the modifications.
