Mammographic heterogeneous density, right breast

This code indicates a finding from a mammogram showing that the tissue in the right breast is composed of scattered areas of fibroglandular density, which could obscure small masses. This density pattern is considered an intermediate level of breast density, between fatty and extremely dense. It is a radiological observation, not a diagnosis of malignancy.

Apply this code when mammography reports specifically document "heterogeneous density" in the right breast. This finding is often noted as part of a screening or diagnostic mammogram interpretation. Documentation must clearly specify the laterality (right breast) and the type of density.

• Ensure the documentation specifies "right breast" to avoid laterality errors.
• Do not use this code for bilateral findings; a separate code exists for bilateral heterogeneous density.
• This code describes a mammographic finding, not a definitive diagnosis of breast disease; additional codes may be needed for any associated pathology or symptoms.
