Unit
Unit means the product represented by the 11-digit National Drug Code, unless otherwise specified by CMS to account for situations where labeling indicates that the amount of drug product represented by a National Drug Code varies. The method of counting units excludes units of CAP drugs (as defined in 414.902 of this part) sold to an approved CAP vendor (as defined in 414.902 of this part) for use under the CAP (as defined in 414.902 of this part).
