R92.32Mammographic fibroglandular density of breast

R92.32 is the ICD-10-CM diagnosis code for Mammographic fibroglandular density of breast. It belongs to category R92 (abnormal and inconclusive findings on diagnostic imaging of breast), block R90-R94 (abnormal findings on diagnostic imaging and in function studies, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within R92.3 (Mammographic density found on imaging of breast), R92.32 is specifically for Mammographic fibroglandular density of breast. Related codes cover dense breasts, unspecified (R92.30), Mammographic fatty tissue density of breast (R92.31), Mammographic heterogeneous density of breast (R92.33) and Mammographic extreme density of breast (R92.34).

To report this condition, pick the subcode that matches the documentation: R92.321 (breast), R92.322 (breast) and R92.323 (breasts).

It was added in FY2024, effective October 1, 2023.
