G0008 - Administration of flu vaccine

Healthcare Common Procedure Coding System

Last updated: 10/30/2025

What is a HCPCS Code?

HCPCS (Healthcare Common Procedure Coding System) codes are used to identify medical procedures, supplies, and services for billing purposes. These codes help standardize how healthcare services are reported and billed across different providers and insurance companies.

Detailed Description

This code represents the service of giving a flu (influenza) vaccine to a patient. It covers the healthcare provider's work in administering the vaccine injection, including preparation, injection technique, and immediate monitoring. This is separate from the cost of the vaccine itself and specifically covers the administration service.

Additional Information

This code covers only the administration service, not the vaccine product itself. Flu vaccines are typically recommended annually for most people 6 months and older. The actual vaccine product would be billed separately.
