Scope/domain statement for the code system
(Official or from HTA)
"The Drug Listing Act of 1972 requires registered drug establishments to provide the Food and Drug Administration (FDA) with a current list of all drugs manufactured, prepared, propagated, compounded, or processed by it for commercial distribution. (See Section 510 of the Federal Food, Drug, and Cosmetic Act (Act) (21 U.S.C. § 360)). Drug products are identified and reported using a unique, three-segment number, called the National Drug Code (NDC), which serves as a universal product identifier for drugs. FDA publishes the listed NDC numbers and the information submitted as part of the listing information in the NDC Directory which is updated daily.
The information submitted as part of the listing process, the NDC number, and the NDC Directory are used in the implementation and enforcement of the Act."
Users should note:
"Starting June 1, 2011, only drugs for which electronic listings (SPL) have been submitted to FDA are included in the NDC Directory. Drugs for which listing information was last submitted to FDA on paper forms, prior to June 2009, are included on a separate file and will not be updated after June 2012."

Users should note a few important items
Arrangement or agreements with HL7 for use of content
|Version management - timing and identification of versions|
The FDA Drug Directory of NDCs is published daily. Use the format YYYYMMDD to refer to a particular distribution. Implementers should note that any any point there are additional NDC codes that organizations have assigned but not yet reported to FDA. Therefore, a full set of NDCs (that exists in the marketplace) is unknown and cannot be versioned completely.

|NDC codes have no copyright acknowledgment or license requirements.|

Process to request content change
"To add a new entry, or to correct erroneous or incomplete product data in the NDC Directory, a labeler should submit a new SPL to update the information. See the eDRLS website for instructions on submitting SPL."
Other useful Information
"Current regulations require a registered establishment to update its drug listing data in June and December of each year, or, at the discretion of the establishment, when a change occurs (see 21 C.F.R. § 207.57(c)); therefore, FDA may not yet have been notified of recent changes before updating the NDC Directory. FDA makes every effort to prevent errors and discrepancies in the NDC Directory data."
"Each listed drug product is assigned a unique 10-digit, 3-segment number. This number, known as the NDC, identifies the labeler, product, and trade package size."
For certain purposes, including the proper billing of drug products, an 11-digit NDC may be required. The Centers for Medicare & Medicaid Services (CMS) and other government entities require an NDC as part of their billing claim form. Some government agencies, including HIPAA, may require the NDC in an 11-digit format with leading zeros. Increasingly, private payers require the 11-digit code, but rules can vary greatly.
An example of how the 10-digit and 11-digit formatted NDC relate is shown here as a reference.
