What does NDC stand for in drug claims?

• A. National Drug Code
• B. New Drug Classification
• C. Network Drug Chart
• D. National Distribution Code

Answer: (A)

National Drug Code is the identifier used on drug claims to specify exactly which product is being billed. In the United States, the FDA assigns an NDC to every drug product and its packaging configuration, with the code typically shown in three parts (labeler, product, and package) and written in formats like 5-4-2 or 4-4-2 digits, totaling 10 or 11 digits. This precise identifier helps payers determine the exact product, assess formulary eligibility, calculate reimbursement, and track use. Using the correct NDC prevents billing the wrong product when similar-sounding names exist, since different products or package sizes can have different prices and coverage. The other terms listed aren’t standard identifiers used in drug claims.
