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

Browse all the diagnosis codes used for abnormal findings on diagnostic imaging and in function studies, without diagnosis (r90-r94). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

  • 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]

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
