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
