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 indicates that you either received a flu shot (influenza vaccination) during your visit, or your healthcare provider documented that you had already received your flu vaccination elsewhere. The flu vaccine helps protect you against seasonal influenza viruses and is typically recommended annually for most people 6 months and older. This code is used for billing and tracking purposes to show that your flu vaccination status was addressed during your care.

Additional Information

Flu vaccines are typically covered by most insurance plans as preventive care. The specific vaccine type and timing may vary based on age, health conditions, and current CDC recommendations.
