G0008 - Giving a flu shot (influenza vaccination)

Healthcare Common Procedure Coding System

Last updated: 10/3/2025

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 covers the service of administering an influenza (flu) vaccine to a patient. This includes the healthcare provider's time and expertise in giving you the vaccination, but does not include the cost of the vaccine itself (which is billed separately). The flu shot is typically given as an injection in your upper arm and helps protect you from getting the flu during the upcoming flu season.

Additional Information

The flu vaccine is recommended annually for most people 6 months and older. This code only covers the administration fee - the vaccine itself is billed with a separate code. Common side effects include mild soreness at the injection site. The CDC recommends getting vaccinated by the end of October each year.
