R93.42Abnormal radiologic findings on diagnostic imaging of kidney

R93.42 is the ICD-10-CM diagnosis code for abnormal radiologic findings on diagnostic imaging of kidney. 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 R93.4 (abnormal findings on diagnostic imaging of urinary organs), R93.42 is specifically for abnormal radiologic findings on diagnostic imaging of kidney. Related codes cover renal pelvis, ureter, or bladder (R93.41) and other urinary organs (R93.49).

To report this condition, pick the subcode that matches the documentation: R93.421 (kidney), R93.422 (kidney) and R93.429 (kidney).

It was added in FY2017, effective October 1, 2016.
