Invalid National Drug Code for the 2020-2021 Flu Season

National Government Services has noticed a large amount of claims being billed for the 2020-2021 flu season with the incorrect CPT codes for influenza flu vaccines.

The NDCs change each influenza season. The NDC must be included in Loop 2410 LIN segments of the electronic claim (Item 19 on the CMS-1500 paper claim). Each box of vaccine includes the NDC assigned by the manufacturer. The correct NDC and HCPCS code for the influenza vaccine must be billed in order for your claim to process, incorrectly billed claims will be denied.

As a reminder, please review and use the appropriate flu vaccine code to avoid processing delays and claim denials on the CMS Seasonal Influenza Vaccines Pricing web page.

Please note: Pricing information for the G0008 administration code is located on the Fee Schedule Lookup web page under the Admin for Flu/PPV/Hepatitis Fee Schedules section.
