Mammographic fibroglandular density, right breast

This code indicates a finding on a mammogram where the right breast tissue appears dense due to a higher proportion of glandular and fibrous tissue compared to fatty tissue. This is a common and normal variation in breast composition, not a disease, but it can impact the sensitivity of mammography for detecting abnormalities.

Use this code when mammography reports specifically document fibroglandular density in the right breast. This finding is often noted as part of a breast density assessment, particularly when categorized as heterogeneously dense or extremely dense. Documentation should clearly specify the laterality.

• Ensure the documentation specifies "right breast" for accurate laterality.
• Do not confuse this with a specific breast lesion or mass; it describes the overall tissue composition.
• This code is often reported in conjunction with screening or diagnostic mammography codes.
