The NDC - HCPCS crosswalks are intended to help understand which drug products -identified by NDCs- are assigned to which HCPCS billing codes. The information is based on published drug and biological pricing data and information submitted to CMS by manufacturers. The crosswalks are not intended to be a comprehensive list of all NDCs available in the United States. The NDC to HCPCS Crosswalks also include information on the NDC package size and the number of billable units.
