Mammographic extreme density, right breast

This code indicates a finding of extremely dense tissue in the right breast as identified on a mammogram. This breast density classification signifies that the breasts are almost entirely composed of fibroglandular tissue, which can obscure the detection of masses and is associated with an increased risk of breast cancer.

Use this code when mammography reports specifically document "extreme density" or "BI-RADS D" for the right breast. This finding is typically reported by a radiologist after interpreting a screening or diagnostic mammogram. Documentation must clearly specify the laterality (right breast) and the degree of density.

• Ensure the documentation specifies "extreme density" (BI-RADS D) and not other density classifications like heterogeneous or scattered fibroglandular.
• Verify laterality; use the appropriate code for left (R92.342) or bilateral (R92.343) if applicable.
• This code represents a mammographic finding, not a definitive diagnosis of breast cancer, and may be coded in conjunction with other breast-related diagnoses or findings.
