G0103 - Blood test to screen for prostate cancer using PSA (prostate-specific antigen)

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 is a screening test that measures the level of prostate-specific antigen (PSA) in your blood. PSA is a protein produced by the prostate gland, and elevated levels may indicate the presence of prostate cancer. This test is used as a screening tool to help detect prostate cancer early, before symptoms appear. The test involves a simple blood draw and is typically recommended for men at certain ages or with risk factors for prostate cancer.

Additional Information

This is a screening test, not a diagnostic test. Elevated PSA levels don't necessarily mean cancer is present, as PSA can be elevated due to other conditions like enlarged prostate or infection. Coverage may vary by insurance plan and patient age/risk factors.
