Over 90% of prescription drugs and over-the-counter medications sold in the United States carry a unique National Drug Code (NDC), a standard identifier that is often converted into an **11-digit drug code** for administrative purposes like billing and claims processing. This numerical code serves as a universal product identifier for human drugs.

Over 800,000 active drug products are identified by a National Drug Code (NDC) in the US, but healthcare providers must use a specific NDC code qualifier, like 'N4', when submitting claims to ensure proper processing and reimbursement. This qualifier is not part of the drug's label but is a crucial administrative code.
