Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code represents a routine screening mammogram visit specifically for detecting breast cancer in patients without symptoms. This is a preventive healthcare service used to identify potential breast cancer early, before any signs or symptoms appear. The screening is performed on patients who do not currently have breast problems or symptoms.

Additional Information

This is a Z-code indicating a reason for healthcare encounter rather than a diagnosis. Used for routine preventive screening in asymptomatic patients.
