Mammographic microcalcification found on dx imaging of brst

This code signifies the incidental finding of microcalcifications within breast tissue as identified through diagnostic imaging, typically mammography. These are tiny calcium deposits that can sometimes be an early indicator of breast cancer, though often benign. It describes the finding itself, not a definitive diagnosis of malignancy.

Use this code when diagnostic imaging reports, such as a mammogram, ultrasound, or MRI, specifically identify "microcalcifications" in the breast. This code is appropriate when the clinical significance of these microcalcifications is still under investigation or when they are determined to be benign. Documentation should clearly state the presence of microcalcifications.

• Do not use this code if the imaging report specifies "calcification" or "calculus" without the "micro" prefix; refer to the Excludes2 note.
• This code is for the finding of microcalcifications; if a definitive diagnosis of a benign breast condition or malignancy is subsequently made, that specific diagnosis code should be used instead.
• Always review the full radiology report to differentiate between microcalcifications and other types of calcifications.
