Incorrect NDC numbers can be problematic and have several implications. An incorrect code could be fraudulent, indicating that patients are receiving a counterfeit version of the product instead of the authentic version. Additionally, an inaccurate NDC may lead to insurance fraud if the product is billed against a code that doesn’t match the administered drug or biologic. Finally, incorrect use of NDCs could also create big issues with pharmaceutical data exchange centers, which are used to confirm eligibility for financial and other benefits programs.
