It should be noted that many National Drug Codes (NDC’s) are being displayed on drug packaging in a 10-digit format. Proper billing of an (NDC) requires an 11-digit number in a 5-4-2 format. Converting (NDC) from a 10-digit to an 11-digit format requires a strategically placed zero (0), dependent upon the 10-digit format. The following table shows common 10-digit (NDC) formats indicated on the packaging and the associated conversion to an 11-digit format, using the proper placement of a zero. The correctly formatted, additional “0” is in bold font in the following examples.
Note: Hyphens shown below are used solely to illustrate the various formatting examples for (NDC’s). Do not use hyphens when entering NDC codes in Freedom | EHR.
