R920 - Small calcium deposits found on breast imaging

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 indicates that tiny calcium deposits called microcalcifications were detected during diagnostic breast imaging (such as mammography). Microcalcifications are small white spots that show up on mammograms and are made of calcium. While most microcalcifications are benign (not cancerous), their pattern, shape, and distribution help doctors determine if further evaluation is needed. This is a diagnostic finding code used to document what was seen on the imaging study.

Additional Information

This is a finding code that documents what was observed on imaging. The significance of microcalcifications depends on their characteristics and pattern. Most are benign, but some may require additional evaluation.
