Healthcare Common Procedure Coding System

Last updated: 11/28/2025

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 low-dose computed tomography (CT) scan that is specifically performed to screen for lung cancer. This is a specialized imaging test that uses lower amounts of radiation than a standard CT scan while still providing detailed images of the lungs to detect potential early signs of lung cancer in people who meet certain screening criteria.

Additional Information

This is a preventive screening test designed to detect lung cancer early when it may be more treatable. The low-dose technique reduces radiation exposure while maintaining image quality sufficient for screening purposes.
