What This Code Means
R93.429 is the ICD-10-CM diagnosis code for abnormal radiologic findings on diagnostic imaging of unspecified kidney. An imaging test shows an abnormal finding in a kidney, but it is unclear which kidney is affected or both kidneys may be involved. R93.429 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering abnormal findings on diagnostic imaging and in function studies, without diagnosis (r90-r94).
R93.429 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code when laterality (left vs. right) cannot be determined from the imaging report.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R93.429 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
