R93.4Abnormal findings on diagnostic imaging of urinary organs

R93.4 is the ICD-10-CM diagnosis code for abnormal findings on diagnostic imaging of urinary organs. It belongs to category R93 (abnormal findings on diagnostic imaging of other body structures), 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 R93 (abnormal findings on diagnostic imaging of other body structures), R93.4 is specifically for abnormal findings on diagnostic imaging of urinary organs. Related codes cover abnormal findings on diagnostic imaging of skull and head, not elsewhere classified (R93.0), abnormal findings on diagnostic imaging of heart and coronary circulation (R93.1), abnormal findings on diagnostic imaging of liver and biliary tract (R93.2), abnormal findings on diagnostic imaging of other parts of digestive tract (R93.3), abnormal findings on diagnostic imaging of other abdominal regions, including retroperitoneum (R93.5), abnormal findings on diagnostic imaging of limbs (R93.6), abnormal findings on diagnostic imaging of other parts of musculoskeletal system (R93.7), abnormal findings on diagnostic imaging of other specified body structures (R93.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: R93.41 (bladder), R93.42 (kidney) and R93.49 (organs).

The conditions in its Excludes2 note aren't part of R93.4, but may be coded alongside it if the patient has both: hypertrophy of kidney (N28.81).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (expanded into subcodes).
