Final answer:
The first set of NDC numbers represents the labeler code, which is the company that manufactures, repacks, or distributes the drug. It is assigned by the FDA and is crucial for tracking and identification of medication.
Step-by-step explanation:
The first set of numbers in a National Drug Code (NDC) indicate the labeler code, which is assigned by the Food and Drug Administration (FDA). The labeler code refers to the entity that manufactures, repacks, or distributes the drug.
An NDC is a unique 10-digit, three-segment number that acts as a universal product identifier for human drugs in the United States. The first set, the labeler code, is typically four or five digits long and represents the company that produces or distributes the drug. The second set of numbers, the product code, identifies a specific strength, dosage form, and formulation for that particular drug from that labeler. And the last set, the package code, specifies the package sizes and types.
For example, if the NDC is 12345-6789-12, ‘12345’ is the labeler code, ‘6789’ is the product code, and ‘12’ represents the package code. It's important for healthcare providers to pay attention to these codes because they are crucial for tracking, identification, and management of medication.
