Healthcare Common Procedure Coding System

Last updated: 5/22/2026

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 your first annual wellness visit with your healthcare provider. During this visit, your doctor will create a personalized prevention plan of service (PPS) tailored to your health needs. This is a preventive care visit focused on keeping you healthy rather than treating illness. The visit typically includes reviewing your medical history, current health status, and developing a customized plan for preventive screenings, vaccinations, and health maintenance based on your age, risk factors, and health goals.

Additional Information

This is specifically for the initial annual wellness visit where a personalized prevention plan is created. Subsequent annual wellness visits would use a different code.
