About the R92 Code Range
Breast imaging can show abnormal findings or leave a finding inconclusive without identifying a diagnosis. These codes describe the imaging findings, not a named breast condition.
R92.0 identifies mammographic microcalcification, a small calcium finding. R92.1 identifies mammographic calcification, while R92.2 describes an inconclusive mammogram. R92.8 groups other abnormal or inconclusive breast imaging findings.
Under R92.3, density separates into unspecified dense breasts, fatty tissue, fibroglandular, heterogeneous, and extreme density. Each named density type further separates right, left, and bilateral breasts.
