Which statement about NDC identifiers is true?

• A. NDC identifies only the manufacturer
• B. NDC is used in billing systems only
• C. NDC identifies a product, dosage form, and package size
• D. NDC identifies the manufacturer, product, dosage form, and package size

Answer: (D)

NDC identifiers are a packaging and product code system that tells you three essential things about a drug item: who made it, exactly which product it is (including its dosage form and strength), and how it is packaged. The first segment identifies the labeler, the entity that manufactures or distributes the drug. The second segment identifies the specific product, which covers the drug itself along with its dosage form and strength. The third segment specifies the package size and type, such as bottle size or blister pack. This structure ensures that a medication can be accurately identified for dispensing, inventory, and billing across systems. Because the product portion includes the dosage form as part of identifying the drug, the overall description that the NDC pinpoints the manufacturer, product (including dosage form), and package size is accurate. The other statements miss aspects of what the NDC conveys, such as not being limited to the manufacturer or to billing alone.
