R92.341

Mammographic extreme density, right breast

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R92.341 is a billable code used to indicate a diagnosis of mammographic extreme density, right breast.

Key Diagnostic Point:

Mammographic extreme density refers to a condition where the breast tissue appears denser than normal on a mammogram. This increased density can obscure the visibility of tumors or other abnormalities, making it challenging to detect breast cancer. Extreme density is typically classified as having more than 75% of the breast tissue appearing dense. This condition can be a normal variant in some women, particularly those with a higher proportion of glandular tissue compared to fatty tissue. However, it can also be associated with an increased risk of breast cancer, necessitating further evaluation. Patients may not exhibit any symptoms, but the finding is significant during routine screening mammograms. Follow-up imaging, such as ultrasound or MRI, may be recommended to further assess any areas of concern. It is crucial for healthcare providers to document the degree of density and any additional findings to ensure appropriate management and follow-up.
