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 a subsequent (follow-up) annual wellness visit that includes creating or updating a personalized prevention plan of service (PPS). This is typically the second or later annual wellness visit, building on your previous wellness visit. During this visit, your healthcare provider will review your health status, update your personalized prevention plan based on your current health risks and needs, and discuss preventive care services that may be appropriate for you.

Additional Information

This is specifically for subsequent annual wellness visits, not the initial visit. The personalized prevention plan is updated based on current health status and risk factors.
