ICD-10-CM › R00-R99 › R90-R94 › R92.3 Mammographic density found on... › R92.32

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2024 onwards. It has never been valid for submission on its own.

Submit one of these 3 more specific codes instead:

• R92.321 Mammographic fibroglandular density, right breast
• R92.322 Mammographic fibroglandular density, left breast
• R92.323 Mammographic fibroglandular density, bilateral breasts

What has happened to this code

Official coding rules

Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.

Inherited from the R90-R94 section Abnormal findings on diagnostic imaging and in function studies, without diagnosis (R90-R94)

Excludes1 - never coded here

• abnormal findings on antenatal screening of mother (O28.-)
• diagnostic abnormal findings classified elsewhere - see Alphabetical Index

Includes

• nonspecific abnormal findings on diagnostic imaging by computerized axial tomography [CAT scan]
• nonspecific abnormal findings on diagnostic imaging by magnetic resonance imaging [MRI][NMR]
• nonspecific abnormal findings on diagnostic imaging by positron emission tomography [PET scan]
• nonspecific abnormal findings on diagnostic imaging by thermography
• nonspecific abnormal findings on diagnostic imaging by ultrasound [echogram]
• nonspecific abnormal findings on diagnostic imaging by X-ray examination

How CDC's index refers to this code

Wording from the official alphabetic index. Much of it appears nowhere in the code description, which is why a search for the everyday phrase so often finds nothing.

• BI-RADS
• Dense breasts
• Breast > Imaging Reporting and Data System: B
• Breast > Imaging Reporting and Data System: 2
• Density > breast > mammographic > fibroglandular
