R92.332

Mammographic heterogeneous density, left breast

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R92.332 is a billable code used to indicate a diagnosis of mammographic heterogeneous density, left breast.

Key Diagnostic Point:

Mammographic heterogeneous density refers to the presence of varying densities in breast tissue as seen on a mammogram. This finding indicates that the breast tissue is composed of both fatty and dense glandular tissues, which can obscure the visualization of potential abnormalities such as tumors. Heterogeneous density is significant because it may increase the risk of breast cancer and complicate the interpretation of mammograms. Patients with this finding may not exhibit any symptoms, but it is crucial for radiologists and clinicians to monitor these patients closely. Follow-up imaging or additional diagnostic procedures may be warranted to rule out malignancy, especially if there are other risk factors present. The left breast designation specifies the side affected, which is important for accurate diagnosis and treatment planning.

Frequently Asked Questions

What does heterogeneous density mean in a mammogram?

Heterogeneous density indicates that the breast tissue has areas of varying density, which can make it more challenging to detect abnormalities. It is important for radiologists to assess these findings carefully.
