(3) Master Cross Reference List L-3. Listed CAGE code sequence, the
MCRL-3 contains the same data elements as the MCRL-l and MCRL-2. Data in the
MCRL-3 is first sequenced by CAGE and then by reference number and crossed to a
NSN and Item Name.
(4) National Drug Codes. National Drug Codes (NDC) will appear as
referenced numbers in the MCRL. The numbers will appear with the prefix "NDC"
followed by the NDC. Each drug product listed under Section 510 of the Federal Food
Drug and Cosmetic Act is assigned a unique 10-digit 3-segment number. This number,
known as the NDC identifies the labeler/vendor, product, and trade package size. The
first segment, the labeler code, is assigned by the FDA. A labeler is any firm that
manufactures or distributes a drug product. The second segment, the product code
identifies a specific strength, dosage form, and formulation for a particular labeler. The
third segment, the package code, identifies trade package sizes. Both the product and
package codes are designed by the labeler. The NDC is in one of the following
configurations: 4-4-2, 5-3-2, or 5-4-1. In some cases where products were submitted by
the manufacturer for an "Own label" distributor, the product/package code portions of
the NDC were not assigned. Every effort was made to obtain a full NDC number from
the manufacturer of the distributor, but their efforts were not always successful. In such
instances, product/package coded were assigned by FDA. Therefore, product/package
code conflicts may exist that cannot be resolved until the data is updated by the affected
establishments.
Section III. SAMPLE PAGES OF THE MEDICAL CATALOG
2-26. EXTRACTS OF FEDERAL SUPPLY CATALOG
The Appendix at the end of this subcourse contains 36 microfiche frames of the
Medical Catalog. These represent most of the information you will need to understand
how to read the catalog. This is but a very small sample considering Volume I is over
200 microfiche pages, Volume II is nine pages, and Volume III is nine pages. There are
270 possible frames per page, so the entire Medical Catalog is about 60,000 printed
pages.
2-27. DESCRIPTION OF EXTRACTED MICROFICHE FRAMES
a. Introduction Table of Contents (pages A-2 & 3). This is a table of contents
of the introduction found on the first microfiche page. From this index, you can go
directly to a certain frame number for the information that you may require. For
example, if you want to find a unit of issue, you would go to frame 8-08.
b. Introduction (pages A-4 & 5). This part provides guidance to the user in
locating information contained in the publication.
c. Therapeutic Index Table of Contents (pages A-6 & 7). This is an
