R928 - Unusual or unclear findings on breast imaging (like mammogram, ultrasound, or MRI)

International Classification of Diseases

Last updated: 10/11/2025

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 is used when breast imaging tests (such as mammograms, ultrasounds, or MRIs) show findings that are abnormal but don't clearly point to a specific diagnosis. The results may be inconclusive, meaning doctors need more information or additional tests to determine what the findings mean. This doesn't necessarily indicate cancer or a serious condition - it simply means the imaging showed something that requires further evaluation or monitoring to understand better.

Additional Information

This is a diagnostic code used for billing purposes when imaging results are abnormal but inconclusive. The specific follow-up plan will depend on the nature of the findings and should be discussed with your healthcare provider. Many inconclusive findings turn out to be benign (non-cancerous) conditions.
